Title: Constantin Vili Gerea: Innovator in Seismic Data Acquisition

Introduction

Constantin Vili Gerea is a notable inventor based in Pau, France. He has made significant contributions to the field of seismic data acquisition, holding 2 patents that showcase his innovative approaches to characterizing subsurface volumes.

Latest Patents

Gerea's latest patents include a method for obtaining estimates of a model parameter to characterize the evolution of a subsurface volume over time using time-lapse seismic data. This method involves obtaining first seismic data corresponding to an initial time and processing it to create a seismic image of the subsurface. The processing is then reversed for relevant portions of the seismic image to retrieve corresponding first seismic data. Changes within the subsurface volume are characterized by estimating the differences between second seismic data from a later time and the relevant portions of the first seismic data.

Another significant patent by Gerea is a method for acquiring seismic data. This method involves arranging receiver lines equipped with geophones in specific positions to measure seismic waves from the subsoil. The receiver lines consist of first parallel lines and second lines located in intermediate positions. Seismic waves are emitted from source positions along the first receiver lines, and the resulting seismic data is processed using seismic interferometry to estimate additional seismic data from a virtual source.
