Wellbore and Reservoir Geomechanics
Prerequisites
BSc courses in PE
Synopsis
Aims: To provide the geo-mechanical background and skills in the quantification of the mechanical properties of reservoir rocks and deformation processes of relevance to petroleum engineering. Objectives: Departing from the already familiar concepts of strain and stress Young’s modulus and Poisson’s ratio, and elastic versus visco-plastic irreversible deformation, this lecture will explain how reservoir rocks deform (rheology), and the stress- and fluid pressure states they are in before and during production. This analysis also necessitates a review of natural / induced faulting and fracturing and the corresponding patterns and structures that often confine or occur within hydrocarbon reservoirs. The concepts: compaction, strain hardening and softening, strain localization, tensile and shear failure, constitutive models, the relationship between fluid pressure and effective stress, the yield-envelope, and typical stress states of the earth’s crust will be explained in sufficient detail to understand reservoir geo-mechanical studies and field tests. Special emphasis will be placed on stress measurement and wellbore stability (breakouts, hydraulic fracture etc.) as well as the deformation of reservoir rocks under low effective stress / elevated fluid pressure. FEM analysis will be used to investigate stresses and failure in geo-engineering applications. The PDEs governing elastic-plastic behavior and taking into account fluid pressure and flow will be introduced, deriving displacement based FEM formulations. Field studies on the Lost Hill anticline and offshore reservoirs in the western US will be used to illustrate these concepts in practice.
Objective
Course participants will learn standard techniques to evaluate the state of stress, fluid pressure regime, constitutive behavior and failure envelope for most common sedimentary rocks. This will enable them to assess borehole stability, the poroelastic response of a reservoir, and the risks of reservoir compaction and disintegration / sand production.

Advanced Well Monitoring and Analysis
Advanced Well Monitoring and Analysis
Prerequisites
Comprehensive knowledge about well drilling, logging, testing completions, servicing, reservoir management and production engineering. Completion, well servicing, production, reservoir and field personnel involved in gathering and interpreting data.
Synopsis
Collecting the data, information and events over the whole well, reservoir and field life cycle, their validation and analysis and transformation open various possibilities to learn and make collected data as valuable tools and new knowledge for fast and effective learning. It is a well-known that data, used for analysis of oil and gas well and reservoir performance (geological, drilling, well servicing, production, processing, economic, etc.) are not the data registered in short period of time, but they are every day, weekly or monthly data. When the data and information are registered, the response has to be prompt, because even the smallest delay in analyst’s reaction inevitably leads to loss of control over the wells’ and reservoirs’ performance. New registered data is always a new time signal that has to be directed in timely manner to corresponding location for the purpose of analysis. Well operation and production history data are recorded and stored on daily basis, and include “hidden” information on potential problem causes that have led to oil production decrease. Selection of well candidates for performing certain operation (workover and/or stimulation) requires knowing general well operating characteristics and a number of specific requirements in well performance, as well as different parameters which allow identification and development of different key performance indicators to quantify operation efficiency of well, reservoir and field and to estimate saving potential if proper corrective actions would be applied. The student will be learned how to prioritize the best candidates for solving the operational problems and increase petroleum production. The frequency of a problem class occurrence, as well as the fact that oil and gas production is basically a time sequence in which certain signals (e.g. oil/water/gas production) or phenomena (paraffin scaling in tubing, inorganic scaling at injection, pump damage, etc.) oscillate in time with typical frequency and phases. Establishing an internal functional and logic dependence between data, information and events is used for generating a well operation learning curve. The various data mining tools will be used to recognize the symptoms and to diagnose the problems in well operations and to allow students better understanding the value of data and information collected during monitoring and surveillance of well operations, both, in real and episodic time. Based on what is known about the field/reservoir, it would be discussed additional tools needed to check and exam well files and data with an aim to evaluate the most likely opportunities. Prior making the final decision whether the well is or not candidate for workover/stimulation, student will be acquired with knowledge how to effectively apply economic analysis to justify the proposed technical solutions.
Objective
The students will lean how to organize big data volume (data, information, events and knowledge) to perform well analysis and to apply problem analysis methodology. Systematic approach to manage big data will be applied with the focus on the value of the data, symptoms recognition methodology and problem diagnosis. The course will allow a deeper understanding concerning the value of various type of data collected during long well and reservoir life cycle. Furthermore, the student should learn how to use the tools to manipulate such data and to convert them to useful information and knowledge with aim to achieve efficient data monetization and produce smarter from maturated brown fields and new discovered green fields.

Synopsis
The world is full of data and the data volumes are exploding. But what is often lacking is a way to make the data usable. Data may or may not contain some essential things. The big question is how to get such information out of the data. In the past we humans were the brain for everything, but nowadays understanding and interpreting this data and information-rich world is a challenge that can’t be tackled without the support of computers and fancy algorithms. The course starts with data acquisition and carries on via data QC/QA until building models based on the data combined with some (petroleum) expert know-how for providing decisions or predictions or at least decision support. The whole course is, of course, accompanied by the required math. In the framework of data acquisition, the sampling theorem will lead to the understanding of aliasing and the impact of the sampling process itself on the data. The Fourier and Hilbert transform as well as some filtering principles based on the convolution integral will support the understanding of noise reduction in the context of data QC/QA. Outlier detection and missing values handling as well as the tackling of time-shift problems are a separate chapter in that block. In the context of the model building, deterministic models – for e.g. dynamometer card analysis, liquid loading detection – in combination with heuristic models – e.g. Bayesian inference, neural networks, static and dynamic committee machines – will be discussed and applied. This second part of the two-part course gives a short review about data QC and modelling with statistical methods.

Continuing with the principles of heat transfer, the heat equation is discussed, and the three modes of heat transfer – conduction, convection & radiation - are reviewed in detail. Incorporating and developing Fourier’s law, Newton’s law of cooling, and the Stefan-Boltzmann law of pollution, the fundamentals for a wellbore heat transfer model will be elaborated. Particular emphasis is given to the impact of natural and forced convection on the heat transfer, including correlation models based on Nusselt-, Grashof-, Reynolds- and Prandtl numbers. Based on the conservation of mass, momentum, and energy, the principal equations for wellbore heat transfer are derived.

Prerequisites
Space-Time Discretization of Flow and Transport Equations
Synopsis
Aims: Following the objectives set out in Space-Time Discretization of Flow and Transport Equations, and taking them further, the aim of this course is to familiarize participants with the non-linear governing partial differential equations arising from reservoir physics, and the numerical / discretization methods used to simulate with them. Linearizing assumptions are removed sequentially through conceptual examples, and complexity is uncovered through different approaches designed to deal with each case. Learning all of these techniques requires studying some of the most important physical processes in a reservoir and their mathematical interpretation to ultimately construct a simulator code. In this manner, the aim is to expand and consolidate the student’s understanding of what happens in the underground. Objectives: In sequence, the course covers the conceptualization of flow-related processes in a reservoir and its surroundings. These processes and their interactions are formalized in terms of governing partial differential equations (PDEs). Their discretization and numerical solution with either the Finite-Volume or Finite-Element Methods (FVM, FEM) is illustrated. The course also covers the design of numerical experiments and visualization, analysis, and interpretation of simulation results. Special emphasis is placed on the non-linear aspects of two phase fluid flow in porous media.
Objective
Successful participants will understand how FEM/FVM methods and associated space-time discretization methods can be employed to solve multiphase flow equations (through two phase examples). Students will obtain valuable knowledge through the implementation of features used by the newest black-box commercial simulators. This will aid them in their work with any simulator they use, for whatever purpose.

Advanced Production Data Analysis and Modelling
Advanced Production Data Analysis and Modelling
Prerequisites
Oil and Gas Production Principles, Artificial Lift Systems
Synopsis
The world is full of data and the data volumes are exploding. But what is often lacking is a way to make the data usable. Data may or may not contain some essential things. The big question is how to get such information out of the data. In the past we humans were the brain for everything, but nowadays understanding and interpreting this data and information-rich world is a challenge that can’t be tackled without the support of computers and fancy algorithms. The course starts with data acquisition and carries on via data QC/QA until building models based on the data combined with some (petroleum) expert know-how for providing decisions or predictions or at least decision support. The whole course is, of course, accompanied by the required math. In the framework of data acquisition, the sampling theorem will lead to the understanding of aliasing and the impact of the sampling process itself on the data. The Fourier and Hilbert transform as well as some filtering principles based on the convolution integral will support the understanding of noise reduction in the context of data QC/QA. Outlier detection and missing values handling as well as the tackling of time-shift problems are a separate chapter in that block. In the context of the model building, deterministic models – for e.g. dynamometer card analysis, liquid loading detection – in combination with heuristic models – e.g. Bayesian inference, neural networks, static and dynamic committee machines – will be discussed and applied. This second part of the two-part course gives a short review about data QC and modelling with statistical methods. However, the main content focuses on model building with heuristic methods such as neural networks.
Objective
The course gives insight into the (increasing) role of data in the oil & gas production business. Participants are trained in learning by doing throughout the whole course. Necessary tools are provided or recommended as well as created by the participants’ themselves by programming it in VBA.

Advanced Well Construction
Advanced Well Construction
Prerequisites
List of compulsory prior lectures
Synopsis
The course consists of 3 parts: Geo-Mechanics, Advanced Drilling and Well Planning. The Geo-Mechanics part covers the following topics and necessary fundamentals of geo-mechanics for wellbore applications: the origin of stresses in the subsurface and how in situ stresses can be understood from wellbore data; mechanical properties such as rock strength, and the origins of pore pressure and how it is measured and estimated. The course then proceeds to show how these data are applied through the Mechanical Earth Model to critical problems in exploration and field development. This multi-disciplinary course provides a concise overview of basic rock mechanics and its application to wellbore stability and lost circulation. In the Advanced Drilling part specific problems associated with vertical and directional/horizontal drilling are discussed such as drill string fatigue design, advanced casing design (tri-axial, design for H2S applications), torque & drag (includes: drilling and pipe running operation), advanced hydraulics, surge & swab, hole cleaning & cutting transport and bottom hole assemblies design. Participants will receive instruction on planning and evaluating horizontal wells based on the objectives of the horizontal well. Additionally, they will become familiar with the tools and techniques used in directional drilling such as survey instruments, bottom hole assemblies, motors, steerable motors, and steerable rotary systems. Extended reach drilling, HPHT drilling and underbalanced drilling is also discussed in this part of the lecture. In the Well Planning part of the lecture students will learn to plan well using different modules of ‘Landmark’. Anti-collision planning, casing stress calculations, T&D soft-string modeling or applied hydraulics design are among the topics solved with ‘Landmark’ with the help of real well data.

Advanced Well Monitoring and Analysis
Advanced Well Monitoring and Analysis
Prerequisites
Comprehensive knowledge about well drilling, logging, testing completions, servicing, reservoir management and production engineering. Completion, well servicing, production, reservoir and field personnel involved in gathering and interpreting data.
Synopsis
Collecting the data, information and events over the whole well, reservoir and field life cycle, their validation and analysis and transformation open various possibilities to learn and make collected data as valuable tools and new knowledge for fast and effective learning. It is a well-known that data, used for analysis of oil and gas well and reservoir performance (geological, drilling, well servicing, production, processing, economic, etc.) are not the data registered in short period of time, but they are every day, weekly or monthly data. When the data and information are registered, the response has to be prompt, because even the smallest delay in analyst’s reaction inevitably leads to loss of control over the wells’ and reservoirs’ performance. New registered data is always a new time signal that has to be directed in timely manner to corresponding location for the purpose of analysis. Well operation and production history data are recorded and stored on daily basis, and include “hidden” information on potential problem causes that have led to oil production decrease. Selection of well candidates for performing certain operation (workover and/or stimulation) requires knowing general well operating characteristics and a number of specific requirements in well performance, as well as different parameters which allow identification and development of different key performance indicators to quantify operation efficiency of well, reservoir and field and to estimate saving potential if proper corrective actions would be applied. The student will be learned how to prioritize the best candidates for solving the operational problems and increase petroleum production. The frequency of a problem class occurrence, as well as the fact that oil and gas production is basically a time sequence in which certain signals (e.g. oil/water/gas production) or phenomena (paraffin scaling in tubing, inorganic scaling at injection, pump damage, etc.) oscillate in time with typical frequency and phases. Establishing an internal functional and logic dependence between data, information and events is used for generating a well operation learning curve. The various data mining tools will be used to recognize the symptoms and to diagnose the problems in well operations and to allow students better understanding the value of data and information collected during monitoring and surveillance of well operations, both, in real and episodic time. Based on what is known about the field/reservoir, it would be discussed additional tools needed to check and exam well files and data with an aim to evaluate the most likely opportunities. Prior making the final decision whether the well is or not candidate for workover/stimulation, student will be acquired with knowledge how to effectively apply economic analysis to justify the proposed technical solutions.
Objective
The students will lean how to organize big data volume (data, information, events and knowledge) to perform well analysis and to apply problem analysis methodology. Systematic approach to manage big data will be applied with the focus on the value of the data, symptoms recognition methodology and problem diagnosis. The course will allow a deeper understanding concerning the value of various type of data collected during long well and reservoir life cycle. Furthermore, the student should learn how to use the tools to manipulate such data and to convert them to useful information and knowledge with aim to achieve efficient data monetization and produce smarter from maturated brown fields and new discovered green fields.

Production Data Analysis and Modelling
Production Data Analysis and Modelling
Prerequisites
Oil and Gas Production Principles, Artificial Lift Systems
Synopsis
The world is full of data, and the data volumes are exploding. But what is often lacking is a way to make the data usable. Data may or may not contain some essential things. The big question is how to get such information out of the data. In the past, we humans were the brain for everything. Still, nowadays, understanding and interpreting this data and the information-rich world is a challenge that can’t be tackled without the support of computers and fancy algorithms. The course starts with data acquisition and carries on via data QC/QA until building models based on the data combined with some (petroleum) expert know-how for providing decisions or predictions or at least decision support. The whole course is, of course, accompanied by the required math. In the framework of data acquisition, the sampling theorem will lead to the understanding of aliasing and the impact of the sampling process itself on the data. The Fourier and Hilbert transform, as well as some filtering principles based on the convolution integral, will support the understanding of noise reduction in the context of data QC/QA. Outlier detection and missing values handling as well as the tackling of time-shift problems, are a separate chapter in that block. In the context of the model building, deterministic models –e.g., dynamometer card analysis, liquid loading detection – in combination with heuristic models – e.g., Bayesian inference, neural networks, static and dynamic committee machines – will be discussed and applied. This first part of the two-part course focuses on data acquisition and QC/QA as well as on modeling using statistical methods such as linear and logistic regression as well as Bayesian methods.
Objective
The course gives insight into the (increasing) role of data in the oil & gas production business. Participants are trained in learning by doing throughout the whole class. Necessary tools are provided or recommended, as well as created by the participants themselves by programming it in VBA.

Prerequisites
BSc courses in PE
Synopsis
Aims: To provide the geo-mechanical background and skills in the quantification of the mechanical properties of reservoir rocks and deformation processes of relevance to petroleum engineering. Objectives: Departing from the already familiar concepts of strain and stress Young’s modulus and Poisson’s ratio, and elastic versus visco-plastic irreversible deformation, this lecture will explain how reservoir rocks deform (rheology), and the stress- and fluid pressure states they are in before and during production. This analysis also necessitates a review of natural / induced faulting and fracturing and the corresponding patterns and structures that often confine or occur within hydrocarbon reservoirs. The concepts: compaction, strain hardening and softening, strain localization, tensile and shear failure, constitutive models, the relationship between fluid pressure and effective stress, the yield-envelope, and typical stress states of the earth’s crust will be explained in sufficient detail to understand reservoir geo-mechanical studies and field tests. Special emphasis will be placed on stress measurement and wellbore stability (breakouts, hydraulic fracture etc.) as well as the deformation of reservoir rocks under low effective stress / elevated fluid pressure. FEM analysis will be used to investigate stresses and failure in geo-engineering applications. The PDEs governing elastic-plastic behavior and taking into account fluid pressure and flow will be introduced, deriving displacement based FEM formulations. Field studies on the Lost Hill anticline and offshore reservoirs in the western US will be used to illustrate these concepts in practice.
Objective
Course participants will learn standard techniques to evaluate the state of stress, fluid pressure regime, constitutive behavior and failure envelope for most common sedimentary rocks. This will enable them to assess borehole stability, the poroelastic response of a reservoir, and the risks of reservoir compaction and disintegration / sand production.
Grading
One piece of course work (30%), an interim exam (30%) and a final exam on all of the covered material (40%).
