This is a hands-on course that will focus on why pore geometry must be the focal point for carbonate petrophysical analysis. Participants will work with petrographic information, mineralogy data, routine core analysis, capillary pressure, electrical rock properties, NMR, and open hole logs. The importance of Core-Log integration and cross calibration will be shown, as well as the reduction of uncertainty in computed reservoirs properties.
During this five day course, participants will learn about why the petrophysical property analysis is often the key to building a static reservoir description. However, in carbonates, a model that is not cross calibrated from core to logs to seismic, it may result in a large statistical uncertainty. They will also learn about carbonate pore geometry, carbonate systems, total and effective porosity, lithology, and mineralogy. A portion of this course will also focus on core-log calibration, quicklook log analysis, applied capillary pressure, and applied flow units.
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
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.
This course explains how risks and volumes can be assessed in a realistic manner, based on a sound understanding of the geological details of the prospect as well as of its regional geological setting and current play understanding
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.
