Determining the End of Infinite-Acting Behavior for Producing Wells in Closed Rectangles. Report SUPRI TR-19

摘要

During a pressure drawdown test, all wells behave as if they are in an infinite reservoir for a brief period (termed the infinite-acting time). In an attempt to better determine this time for well locations in closed rectangular shapes, we have produced computer and hand calculator programs as well as contour graphs that yield the dimensionless time (in terms of area), t/sub DA/, which defines the end of the infinite-acting period.
