This course covers the necessary fundamentals of geomechanics 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. There are detailed case studies on wellbore stability sand production and hydraulic fracturing. The course also includes an introduction to reservoir geomechanics, showing the geomechanical influence of pressure changes in the reservoir.

This course is also available as a 3 day class without classroom exercises
This course teaches the fundamentals of Petroleum System Analysis (PSA) with an emphasis on deepwater applications. PSA is a relatively new specialization in the field of Petroleum Geology: it investigates the generation of hydrocarbons in the subsurface and tries to reconstruct the filling history of existing oil and gas accumulations with the aim to quantify the charge risk of undrilled prospects. Deepwater environments present the petroleum system analyst with a number of specific challenges, as source rocks are typically beyond the reach of the drill bit and oil-to-source rock correlations are complicated by oil transformation processes such as remigration and biodegradation. After a 3 day introduction of the fundamentals of PSA, case histories from the Gulf of Mexico, offshore West Africa and the Mediterranean are discussed. Special attention is given to geochemical well evaluations, which form an essential part of PSA, not only in the Deepwater environments but also for the evaluation of unconventional hydrocarbons such as Shale Gas and Basin Center Gas.
Fractured reservoirs such as tight carbonates and basements set complex challenges to appraisal and development teams due to their high degree of heterogeneity and hard-to-predict reservoir quality. A multi-disciplinary approach that draws on sedimentology, diagenesis, structural geology, rock mechanics and reservoir engineering techniques has to be applied.
This course provides geologists and reservoir engineers with the essential knowledge needed in the real-world business context where management of risk and reduction of uncertainties is important. The objective is to present the key technical issues in geology, geomechanics and engineering and illuminate the range of tools and techniques available to tackle them (along with their limitations). A constant theme is to illustrate these issues with case histories from the industry.
The course is intended to be interactive in that delegates are encouraged to participate in discussions so that key points are openly scrutinised.
A constant theme of the course is to apply ‘first principles’ from geological science to the results generated by reservoir characterisation tools, techniques and modelling softwares. With due attention to these principles the technical and commercial risks associated with fractured reservoir hydrocarbon developments can be mitigated.
This course teaches you the use and limitations of a variety of production logging tools including spinner, temperature, noise, fluid injections and others tools. You will learn what results these tools yield, the interpretation assumptions that are integral to their designs, and how quality is affected by the acquisition process. You will also learn the fundamentals of production log interpretation with hands-on examples and an in-class workshop on interpreting single and two phase flow using production logs. You will learn how production logs can be used for the measurement of 3 phase fluid flow.
Participants will learn how to take hydrocarbon volumes and risks and apply a structured decision analysis process to them. The portfolio optimization process will also be discussed in order to help participants understand how to select the “best” exploration projects.
The comparison of exploration projects under different fiscal regimes will be presented by incorporating discounted cash flow and net present value. The basics of decision analysis for exploration will be reviewed using sensitivities, decision trees, expected monetary value, and the value of information.
This course addresses the problem of accurate seismic interpretation in deep-water and the delicate construction of seismic maps in the deep-water realm. It is intended to all petroleum professionals involved in exploration and production, geophysicists, geologists, rock physicists, reservoir engineers and drilling engineers.
Seismic interpretation is covered with a series of practical examples that focuses on the deepwater realm, with emphasis on proximal, intermediate and distal marine reservoirs. Acquisition and processing of 2D and 3D data is also discussed in what concerns the practical use of the rather extensive growing database libraries in deepwater.
The distinct data challenges in deepwater are examined in detail so that it would lead to practical problem of drilling locations and the finding and development of deepwater deposits.. Issues in the drilling of deep-water wells such as thickness of the overburden, pore-pressure prediction and geo-steering, are discussed. Practical workshops involve understanding of the main techniques in the seismic section interpretation and in precise structural contouring mapping in deep-water, with focus on the continental slope bathymetry correction and its effect upon time and depth maps. Handling of seismic velocities, depth conversion, comparisons of 2D vs. 3D data, and the principles of 4D and of 4C seismology are also briefly discussed. Time-slice of 3D datasets, seismic interpretation of attributes of amplitude and phase are applied to the mapping exercises for the purpose of better reservoir characterization and possible occurrence of fluid effects.
COURSE OBJECTIVES are the practical understanding of aspects concerning the precise deep-water seismic interpretation fundamental for successfully drilling oil and gas wells in the deep-water realm. Correct estimates of seismic velocities and map contouring techniques in deep-water are essential for achieving ideal vertical and deviated well locations and to the geo-steering of horizontal wells upon reservoir development.
The course covers the essentials of offshore seismic data from acquisition to processing and interpretation. To this effect it examines seismic tape formats, data libraries, design of seismic proprietary and spec surveys, data processing workflows in deepwater and the utilization of interpretation software in workstations Methodologies for correct interpretation of seismic sections and the techniques applied in the architecture details of map contouring are discussed in connection with suites of exercises that apply these techniques in offshore data of passive and compressive continental margins, covering the outer shelf, slope, rise and basin.
Focus is given to the interpretation of deep-water reservoirs, mainly proximal, intermediate and distal turbidites. The main differences between hand-drawn interpretation and computer workstation mapping are discussed so that the principles of interpretation may be utilized to quality control computer section interpretation and computer mapping. This is particularly important in deep-water due to the effect of bathymetry over contouring and depth conversion.
Comparisons between hand contouring and computer contouring are carried out for the purpose of understanding the subtleties of subjective hand contouring versus grid algorithm contouring. Special emphasis is therefore given to hand contouring map interpretation comparisons with modern workstation software grid interpretation mapping for 2D and 3D data sets. Comparative interpretation of the main prospective deep-water regions of the world such as Gulf of Mexico, Offshore Brazil, West Africa, North Sea and Southeast Asia are effected with suite of comprehensive exercises covering structural and stratigraphic interpretation and the use of seismic attributes. Rift and compressional mapping exercises cover normal and reverse faults handling, the understanding of paleo-lows and paleo-highs and flattening of bathymetry for re-construction of basin tectonism. Handling of seismic velocities in deep-water are made with specific exercises of depth conversion. Attendees are daily given hands-on mapping problems and exercises that cover geophysical exploration and development mapping in deep-water. Salt tectonics models over distinct basins are examined and comparisons made for basin architectures and hydrocarbon plays of autochthonous salt vs allochtonous salt.
