This course will focus on the different types of tests and techniques, both analytical and graphical, for data representation and analysis of well tests. Types of techniques covered will include diagnostic plots-derivative for draw down, and buildup tests. Participants will learn about the interpretation of complex data, such as those from well test in naturally fractured reservoirs, hydraulically fractured wells, horizontal wells, along with gas and gas condensate reservoirs. Each day participants will see examples of the types and techniques discussed along with practice problems.
A profitable development of an oil or gas field start with a good understanding of the subsurface as a basis for efficient and successful field management. The use of AVO and inversion techniques helps to create the best possible petrophysics subsurface model. Improved discrimination of reservoir units are made and models are generated using logs and seismic data. These techniques lead to highly accurate or highly probable (static) subsurface models compatible (if correctly up-scaled) to dynamic reservoir models obtained from reservoir engineering measurements and computations.
The correct use of seismic attributes, well data analysis, AVO and seismic inversion is essential to establish subsurface models that can be used for improved field development planning and design.
At the end of the course participants will understand basic concepts in quantitative seismic analysis and interpretation based on AVO, well-to-seismic calibration and inversion techniques. Participants will consolidate their understanding of modern technology with recent field study examples and practical workshop exercises.
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.
The course will cover all the aspects of the fundamentals of cased hole formation and production evaluation. The emphasis during the workshop will be on the fundamental “science” and on the efficient use of logs. The course will also introduce the latest cased hole logging techniques and technology development. A strong element of log quality control is also included, and there are multiple exercises.
The objective of this training is to acquaint attendees briefly with the extensive topic of IOR/EOR processes that exist and in growth for the development of conventional and unconventional resources. The training will cover the following aspects:
- Definition of IOR and EOR
- Reservoir life cycle and fundamentals of fluid displacement in reservoir
- Miscible EOR
- Thermal EOR
- Chemical EOR
- Microbial EOR (MEOR)
- Mobility control as a complement to other EOR processes
- Global EOR projects
This course teaches you advanced techniques for production logging and reservoir monitoring. You will learn to design a data acquisition program to evaluate wellbore or reservoir behavior based on field development objectives. You will learn in-depth log interpretation techniques such as interpreting three phase fluid flow in deviated and horizontal wells. You will also learn quick look techniques for log quality control as well as how to plan and integrate multi-source data to complete your evaluation. Using hands-on examples, you will learn to interpret behind casing resistivity, three phase flow in horizontal wells, and evaluating fluid saturations using logging tools
This course builds on the NExT Fundamentals of Petroleum Geomechanics course and starts to investigate geomechanics beyond simple elastic, isotropic behaviour. After a brief review of fundamental concepts, earth stresses and the Mechanical Earth Model, the course looks at the impact of reversible and non-reversible geomechanical behaviour on drilling, stimulation, sand production and injection looking specifically at thermal, depletion and compaction effects. The course then investigates anisotropy, its nature and effect on geomechanics, and its significance and influence on well construction and field development. The course also covers salt, introducing the mechanics of salt, short term and long term behaviour, as well as the impact on drilling both sub-salt and pre-salt.
At the end of this course participants will recognize the differences and significance of reversible and non-reversible in petroleum applications of geomechanics both in the wellbore and reservoir. They will under-stand the importance of anisotropic behaviour in rocks, know the methods used to measure anisotropy and the effect on well construction and field development. They will also be know about the short and long term mechanical behaviour of salt, the effect of salt on the local stress state and what needs to be considered when developing fields either created by or accessed through salt.
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.
At the end of the course attendees will be able to:
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.
During this course, participants will learn how to apply a structured approach to effective negotiating. Combining this with the practice sessions incorporated into the program this course is designed to improve participants’ confidence in negotiating and improve the outcomes of their negotiations. Attendees will be exposed to the Breakthrough Negotiation Strategy to help them achieve results in difficult and complex negotiations.
The bulk of this interactive course comprises of realistic, oil industry-based, role-play negotiating scenarios based on a variety of commercial and non-commercial situations. This is underpinned with instruction in negotiating principles and methodology, as well as essential checklists for planning and reviewing.
