Challenge: Obtain accurate pressure
measurements for determining the pressure gradient in high-temperature wells
with low-permeability formations.
Solution: Perform pretests at multiple depths
with PressureXpress-HT high-temperature reservoir pressure service, which is
specifically engineered for high- temperature environments and provides precise
control of pretest volume and rate for efficiently and accurately measuring
reservoir pressure and mobility, even in low-permeability formations.
Results: Used PressureXpress-HT services
accurate pressure measurements to construct a valid pressure gradient and
definitively identify the fluid contact for targeting perforation
intervals.
