Abstract

ABSTRACT This paper presents a new, patented1,2 approach to the testing and evaluation of a pumping oil well.3 For an actively pumping well, the test provides the flowing bottom-hole pressure, the flow rate at which gas is liberated up the annulus, and the pumping rate of the bottom-hole pump. When the well is shut in, the technique can be used to determine the bottom-hole pressure as a function of time. This information can be used in conventional pressure-buildup analysis for damage, transmissibility, and static pressures.
