geological assessment of reservoir seals and pay

Course Description

This course demonstrates the use of basic petrographic, wireline and capillary pressure data to evaluate reservoir rock quality, pay vs. non-pay, expected fluid saturations, seal capacity (thickness of hydrocarbon column a seal can hold before it leaks), depth of the reservoir fluid contacts, and thickness of the transition zone. It also explains the use of 2-way capillary pressure analyses to approximate recovery efficiency during primary or secondary recovery. This popular course has received extremely favorable reviews when presented previously to the AAPG, IPA and PESA and as an internal training course for several major oil and gas companies. The course will be a workshop format. Participants will delve into the details of working with data specifically in four exercises.

Audience

• Exploration and development geologists and reservoir engineers will benefit from the straightforward and intuitive presentation of principles governing hydrocarbon accumulations and their practical applications.

Prerequisites

• Basic knowledge of geological and reservoir fundamentals.

Course Schedule

1	Introduction to evaluation of reservoirs, seals and pay Discussion of uses of capillary principles in reservoir evaluation: fundamentals of capillarity, buoyancy vs. capillary pressure, wettability, contact angles, derivation of capillary pressure equations Definition of Free Water Level, description of the porous plate, centrifuge and mercury injection techniques Exercises
2	Demonstrate application of integrated petrophysical and geochemical techniques in evaluation of seal potential Basic principles of fault seal analysis (juxtaposition, fault zone processes, reactivation) Description of seal evaluation in dynamic petroleum systems: example from East Java and Northwest Shelf, Australia Discuss the effects of pore geometry (size, shape, distribution of pores and pore throats) on relative permeability and capillary pressure Exercises
3	Methods of determination of net pay in a reservoir incorporating data from core, sidewall core, cuttings, conventional plug measurements in conjunction with capillary pressure data Predict recovery efficiency, calculate recoverable reserves and evaluate reservoir management options Exercises
