Patent number: 10837244Abstract: A method for determining a concentration of solid particles in a drilling fluid. The method comprises determining, based on a received dimension of a section of a fracture, a plurality of wirelines each having a diameter. For each wireline, the method determines if a solid particle or a part of a fluid is in the current wireline. If it is determined that a solid particle is in the wireline, then determining whether the current wireline is sealed. These steps are reiterated. The method further comprises determining a volume of injected fluid into the fracture and comparing the determined volume with a reference to determine if a fracturing criterion is met. If the fracturing criterion is met, it is possible to modify the current concentration of solid particles.Type: GrantFiled: April 27, 2015Date of Patent: November 17, 2020Assignee: TOTAL SAInventors: Kun Su, Jean-Yves Lansot, Atef Onaisi
