Title: Innovations by Stephane Pierre in Formation Fluid Pressure Measurement

Introduction

Stephane Pierre is an accomplished inventor based in Chatenay-Malabry, France. He has made significant contributions to the field of formation fluid pressure measurement, particularly through his innovative patent. His work is instrumental in enhancing the efficiency and accuracy of pressure determination in earth formations surrounding boreholes.

Latest Patents

Stephane Pierre holds a patent for a method of determining the pressure of formation fluid in earth formations surrounding a borehole. This method utilizes a downhole probe coupled to a variable-volume cavity. The probe is driven into contact with the formation at the borehole wall. The process involves expanding the volume of the cavity during a first period to establish fluid communication between tool fluid and formation fluid, while withdrawing a minimal amount of fluid from the formation. During a second period, the tool pressure equilibrates to formation pressure. Once equilibrium is established, formation fluid pressure is set equal to tool pressure. A preferred embodiment of this invention includes terminating the expansion of the cavity upon detecting a break in the mud cake seal. The associated formation pressure tester tool comprises an elongated body, a probe with a formation fluid inflow aperture, an electromechanical assembly defining a variable-volume cavity, a pretest flow line coupling the aperture to the cavity, a pressure sensor, and downhole electronic means for controlling the expansion of the cavity.
