Patent number: 11124690Abstract: Reducing leak-off during acid stimulation with dissolvable material sized to preferentially block crevices and wormholes, thus allowing the acid to travel further down the fractures, etching deeper into the reservoir than a similar process not using such dissolvable materials. After stimulation, the materials dissolve and production can proceed and will be improved over what is possible without such dissolvable materials.Type: GrantFiled: September 4, 2019Date of Patent: September 21, 2021Assignee: CONOCOPHILLIPS COMPANYInventor: Vibhas Pandey

Patent number: 11124700Abstract: A treatment additive for hydraulic fracturing made of heated silica to create amorphous silicate with a Mohs hardness between 4.5 and 6 and a particles distribution with maximum diameter between 5 and 2600 microns that has been heated and shaped into amorphous shapes with large surface area to weight ratio and ultra-low settling velocity used to prop microfractures distal from well bore, especially in low viscosity and high temperature wells. The microparticle size and shape allow the treatment to effectively hold microfractures open, stimulate backpressure, and prevent leakoff; which has the added benefit of improving primary fracture development; refrac and frac protect productivity; and reduces the likelihood of interference between offset wells. An additional benefit is that the treatment doesn't contain crystalline silica.Type: GrantFiled: September 18, 2020Date of Patent: September 21, 2021Inventors: Michael John Caple, John Stabenau

Patent number: 11119248Abstract: The present invention is related to a method for estimating the fractured volume in a reservoir domain, said fractured volume generated by injecting a high pressure fluid into the reservoir domain. The high pressure fluid generates new fractures allowing a more effective drainage of porous rocks, generally identified as geological material, containing oil or gas. As a result, the effective reservoir volume increases. According to embodiments of the invention, the method provides a dynamic estimation of the fractured volume taking into account the evolution of the rock and the fractures. In other embodiment, the evolution of the fractured volume is estimated by generating an envelope surrounding the induced fractures allowing a better estimation of the fractured volume.Type: GrantFiled: August 20, 2018Date of Patent: September 14, 2021Assignees: REPSOL, S.A., UNIVERSIDAD POLITÉCNICA DE CATALUÑAInventors: Lakshmikantha Mookanahallipatna Ramasesha, José Alvarellos Iglesias, José María Segura Serra, Ignacio Carol Vilarasau, Daniel Garolera Vinent, Pere Prat Catalan
