Title: Marwan Charara: Innovator in Hydraulic Fracturing Technology
Introduction
Marwan Charara is a notable inventor based in Rueil Malmaison, France. He has made significant contributions to the field of hydraulic fracturing, holding a total of 7 patents. His work focuses on improving the methods used to determine the geometric characteristics of hydraulic fractures, which is crucial for the oil and gas industry.
Latest Patents
One of Marwan Charara's latest patents is a method for determining geometric characteristics of a hydraulic fracture. This method involves performing a baseline seismic survey for a geological formation. A velocity model is created by combining results of the baseline seismic survey and additional geoscientific information, allowing for the evaluation of seismic properties of the geological formation. The process includes identifying at least one strong flat lithological reflector disposed below a planned fracture. A numerical model of elastic wave propagation in the geological formation with a fracture is then created. Hydraulic fracturing is performed, and after fracturing, when the fracture is maintained open and pressurized, seismic surveys are conducted. The dimensions and shape of the fracture are determined by comparing the first and second reflected and refracted seismic signals and solving an inverse problem using the numerical model.
Another significant patent involves neutrally-buoyant borehole investigation tools and methods. These tools are designed for seismic data collection and can range from several hundred meters to several kilometers in length. They feature integrated sensors that move along with the borehole fluid in response to passing seismic waves. The methods of deploying these tools include using a tractor or adding weight to overcome the challenges of lowering a neutrally buoyant tool into a borehole. This innovation also provides methods for acquiring seismic data, which involves positioning the tool in a borehole to collect data generated by seismic waves.
