Formation Pressure Testing In the Dynamic Drilling Environment

by Mark A. Proett, Halliburton Energy Services

Abstract:

Formation Testers While Drilling (FTWD) tools have recently been introduced and offer an alternative to wireline testing. Several questions remain regarding the accuracy and repeatability of these measurements. First, the drilling environment is dynamic with hydrostatic pressure constantly changing. Invasion and the resultant supercharge effects can also be factors affecting FTWD measurements. Some FTWD tools offer the capability to perform pressure tests with the mud pumps on or off. Additionally, some FTWD use either inflatable packers or probes which perform very differently depending on the formation properties. The emphasis of this talk is to consider these factors and to use forward modeling sensitivity studies to demonstrate these effects over a wide range of operating conditions. Field data from the new GeoTAP tool is presented to demonstrate the applications of FTWD and provide verification for many of the simulated factors affecting the measurements.
