Synthesis

Program :J1 morning = Module 1 & 2 .World panorama
.Play quality

J1 afternoon = Modules 2 & 3
.Exercise play quality
.Stimulated Rock Volume (SRV) Quality
.Exercise SRV quality

J2 morning Module 4 & 5
.Pilot and development phase
.Development exercise
.Risks and threaths

J2 afternoon Module 6 & 7
.Acceptabiliy
.Debriefing

Méthode :
The first half day presents the fundamentals using presentations and films. Each session ends with a quizz. Sessions 2, 3 and 4 are built around a fictive exercise consisting in choosing the best play and then develop it economically. The exercise allows the students to put in practice the theory presented. The last half day (sessions 6 & 7) is devoted to highlight the acceptability issues related to the development of unconventional resources.

Objectives

.Understand the origins, causes and consequences of the American shale oil & gas revolution .Understand how Oil & Gas are manufactured. Differentiate a source rock from a reservoir (rock nature, trapping mechanism, extension). Identify the main attributes of a source rock (Total Organic Content, shale maturity, pore pressure, thickness, range of permeability) and all methods to assess these attributes. .Understand how to produce an unconventional play using hydraulic fracturing. Identify the main attributes of a SRV (Stimulated Rock Volume) and all methods to assess these attributes. Understand why production quickly decline and why ultimate reserves are low .Understand how the geosciences drivers (extremely low permeability, very large extension, quick decline) impact the development drivers (thousands of wells all horizontal and multi-fractured). The “trial & error” North American method (statistical evaluation of a play without a detailed analysis of geo-attributes) cannot be fully exported outside US. The proposed approach (play & SRV quality approach) relies on a 4G (geology/geophysics/reservoir/Geomechanics) appreciation of the play .Impact of development scheme on the required business model .Impact of the development scheme on the acceptability of the stakeholders. Classification of acceptability issues in nuisances/risks/myths. Each issue is detailed to clearly understand how to mitigate & debunk it.
