Title: Roland Lenormand: Innovator in Hydrocarbon Reservoir Engineering

Introduction

Roland Lenormand is a distinguished inventor based in Rueil Malmaison, France. He has made significant contributions to the field of hydrocarbon reservoir engineering, holding a total of 13 patents. His innovative methods focus on improving the understanding and modeling of underground mediums, particularly in relation to permeability and hydrocarbon production.

Latest Patents

Lenormand's latest patents include a method for determining the permeability of an underground medium from NMR measurements of rock fragments. This method involves measuring permeability from rock fragments and analyzing the NMR signal produced by a device on rock fragments saturated with a protonated liquid. The process aims to obtain optimum values for parameters that relate permeability to the NMR signal, which can then be applied to well zones lacking direct permeability measurements. Another notable patent is a method for modeling the production of hydrocarbons from a subsurface deposit subject to depletion. This method utilizes laboratory measurements to create a model simulating the production of hydrocarbons, allowing for predictions of relative permeabilities and production rates in reservoirs.
