Evaluating Fault and Cap Rock Seals

This volume constitutes the proceedings of the AAPG Hedberg conference on seals held in Barossa Valley, South Australia, in 2002. The key driver for both the Hedberg conference and this publication was the recognition that knowledge of risk in the estimation of sealing capacity and fault-seal potential is important in making judgments at the exploration, appraisal, and development stages of the petroleum business. In addition, incorporating seal risk in the overall assessment of hydrocarbons in place can affect decisions to drill prospects and the location of appraisal and development wells, as well as reserve estimation. Improved methods to estimate seal capacity and fault integrity can lead to savings in well costs, improved recoveries through optimum placement of wells, and improved estimates of hydrocarbon in place. This volume contains 18 chapters that reflect the spectrum of presentations at the conference. The knowledge imparted by these chapters will be a window on the state of seal knowledge at this juncture of time and includes topics such as seal failure related to basin-scale processes, the role of geomechanics in seals, and the economic evaluation of prospects with a top seal risk.
Seals: The Role of Geomechanics

Abstract
Geomechanical analysis is a mechanism for understanding the complex interactions that occur in a deforming system, leading to the ability to predict how that deformation impacts the key physical properties of the rocks, such as those related to fluid flow. Specifically, geomechanics enables us to determine how assemblages of rocks will respond to a loading arrangement, provided that we can also stipulate the complete suite of mechanical behaviors for all of the components of the system. The roles of geomechanical processes, in terms of how they influence the fluid system, are crucial elements in many applied subject areas and...
