Who Should Attend
his course is extremely valuable for exploration and development geologists, geophysicists, petrophysicsts, and Petroleum engineers working in and around salt basins worldwide. It is tremendously beneficial for Pore Pressure Analysts that want to enhance and modify their prediction tools to fit the salt environment. Oil and gas economic feasibility analysts and managers will find this course provides a functional gauge for their assets portfolio.
Participants completing this course will learn to:
- distinguish between the high and low risk salt related prospect;
- understand salt - sediment evolution due to sediment load (overburden), gravity (Isoctacy) and sea level changes (Eustasy);
- comprehend the hydrocarbon trapping mechanism in supra and subsalt plays;
- recognize the uniqueness of salt’s physical properties that leads to the presence of multiple traps ranging from the good, the bad, to the ugly;
- appraise the impact of salt emplacement and displacement on the stresses vectors that lead to entrapments and or breaching of hydrocarbons;
- assess the pore-fracture pressure profile behavior and characteristics above and below the salt;
- evaluate the change in the sediments geopressure profile due hosting the intrusive salt;
- understand the prevalence of oil traps in deep water relative to gas;
- employ the changes in subsurface pressure to appraise prospective object’s sealing, hydrocarbon retention and productivity capacities;
- recognize the large disparity of costs between drilling dirty vs. clean salt;
- foresee the drilling challenges above, within and below the salt mass.
The industry exponentially expanded exploration to new subsalt and pre-salt plays in deepwater since the Mahogany discovery. The high rewards of finding hydrocarbons in deepwater mini-salt basins and frontier salt toe belts make them a very attractive target for exploration endeavors. However, complex subsurface geopressure can cause hydrocarbon breaches and recurrent drilling challenges that drastically increase the operation costs and sometimes leads to the abandonment of a prospect.
The course will proceed from the impact of depositional system on salt mobilization, flow and creeping near the sea floor. We will study the salt’s light density, impermeability and ductile nature that make it a unique catalyst for prospects maturation worldwide.
A good dose of applied pore pressure basics, measurement, and prediction will be taught as an essential segment of the risk assessment. We will focus on the salt dynamic motion, stresses perturbation, isostacy and their impact on subsurface geopressure profile. The course also examines the geopressure system behavior and its accountability for hydrocarbon maturation, migration, entrapment and the challenges to drill supra and subsalt prospects. The sealing and hydrocarbon retention capacities will be discussed in relation to the hydraulic head and the hydrocarbon potential flow and productivity.
The course deals with integrating seismic sequence stratigraphy, geologic setting and the pressure profile created by salt-sediments interaction. Seven risking models will be elaborated on with multiple examples of case histories. The models cover passive domes, diapirs, canopies, sheets, withdrawal basins, ramps, tongues, toes and welds. Examples of success and failure justifications will be demonstrated during the course of the two day class.
Several seismic lines with correlated well logs will be used as exercise materials during the course. In summary, the course is designed to provide participants with incorporated segments of geology, geophysics, geopressure, rock-mechanics and drilling practice under one risk assessment discipline.
