ABSTRACT: Pressure transient
analysis has been used to evaluate performance of a well located between one
sealing fault and one constant pressure boundary. Type curves were generated by determining 1) dimensionless pressure
and 2) rate of change of dimensionless pressure drop with respect to
dimensionless time. When
the well is located closer to the no flow boundary, both sets of type curves have three distinct slopes. These slopes characterize: 1) flow in an infinite reservoir, 2) presence of the no
flow, and 3) the constant-pressure boundaries. When the well is closer to the
constant pressure boundary, the type curves show two distinct slopes. These
correspond to: 1) flow in an infinite reservoir, and 2) the presence of a
constant pressure boundary. The type curves can be used to match actual
pressure drawdown data and determine the drainage area and relative well
location with respect to physical boundaries.
