Title: The Innovative Contributions of Jean Sulem

Introduction

Jean Sulem is a notable inventor based in Paris, France. He has made significant contributions to the field of cement technology, holding a total of 3 patents. His work focuses on methods that enhance the understanding and application of hydrating cement pastes.

Latest Patents

One of Sulem's latest patents is a method for determining a plasticity parameter of a hydrating cement paste. This method involves mixing components to create a cement slurry, which is then poured into a scaled oedometric cell. An oedometric measurement operation is performed within a predefined early-age time interval by applying a specific axial stress path to the cement slurry. The axial strain is measured, and a plasticity parameter is determined through a calibration processing operation that compares simulated axial strain values with actual measurements.

Another significant patent by Sulem is a method for determining a time window in which a casing pressure test can be performed without damaging a cement sheath. This method assesses the hydration degree of the cement at specific pressure and temperature values in a well. By comparing the hydration degree to a predetermined value, it is determined whether the casing pressure test can be conducted safely.
