Abstract
Pressure transient analysis for horizontal wells has gained a lot of attention recently due to the increasing number of horizontal wells. Interpretation of horizontal well test data is much more difficult than for a vertical well. Due to heterogeneity, application of single-layer models fails to interpret the reservoir properties. Numerical methods are essential for a horizontal well in multilayer reservoir with complicated wellbore configuration and boundary conditions.
This paper presents a boundary element method for solving pressure transient behavior of multilayer reservoirs. Two types of boundary conditions, Dirichiet and Neumann, can be handled by the proposed technique. The boundary element method yields several advantages over the conventional finite- different and finite-element methods.
The developed algorithm is successfully applied to some simple cases with known analytical solutions including a finite linear aquifer, a horizontal well in closed reservoir, and a horizontal well in a multilayer reservoir.
