  • Patent number: 11760924
    Abstract: Polymer-coated proppants for hydraulic fracturing of oil and gas wells have an outer layer portion that comprises an organofunctional coupling agent, preferably an organofunctional silane coupling agent. The use of an organofunctional silane coupling agent in the outer layer portion of the proppant coating is preferably chosen to expose functionalities that will be reactive towards similar functionalities of adjacent and similarly coated proppants so that, when introduced downhole, these proppants form interparticle bonds at the temperatures and crack closure pressures found downhole in fractured strata. Such enhanced interparticle bonding helps keep the proppant in the fracture and maintains conductivity with reduced flowback. The invention also helps proppants designed for low temperature well to bond more firmly and allows proppants designed for high temperature wells to bond well even at lower downhole temperatures, thereby extending their useful range.

  • Patent number: 11572501
    Abstract: Well treatment operation comprises introducing nanosized particulates into a formation. The nanosized particulates are synthesized by combining PMIDA, a calcium source, a pH adjusting agent, and an aqueous medium. This combination results in a degradable (i.e., dissolvable) solid that can be used in heterogeneous formations like shale type rock reservoirs, as well as sedimentary rock formations like clastic, siliclastic, sandstone, limestone, calcite, dolomite, and chalk formations, and formations where there is large fluid leak-off due to stimulation treatments. The disclosed particulates may also be used for acidizing treatments in mature fields and deep water formations commonly characterized by high permeability matrices. The solubility of the particulates advantageously allows the material to act as a temporary agent having a lifespan that is a function of temperature, water flux, and pH, making it adaptable to various reservoir conditions with minimal to no risk of adverse effects on the reservoir.

  • Patent number: 10920130
    Abstract: Methods for producing a coating on a fracture surface within a subterranean formation are provided. A pad fluid is injected or introduced into a wellbore to form a primary fracture in the subterranean formation and a coating fluid is injected or introduced into the primary fracture to form secondary fractures in the subterranean formation. The coating fluid is flowed into the secondary fractures to expose nucleation surfaces on the secondary fractures to the coating fluid and to produce a resin coating on the nucleation surfaces. Conductive flow paths are formed on and/or within the resin coating. Hydrocarbons can be retrieved from the subterranean formation via the conductive flow paths within the secondary fractures. A viscosity of the pad fluid is greater than a viscosity of the coating fluid and the coating fluid contains or includes a resin, a curing agent, a surfactant, and an organic solvent.

  • Patent number: 10914139
    Abstract: The disclosure pertains to the increasing the amount of stimulated efficiency and production from a given well area by determining a number of diverter slugs and the timing for the injection of the slugs for the given well area. A number of data sets are determined using Monte Carlo analysis, each data set including a quantity of diversion slugs and the timing for the injection of the diversion slugs. A simulation is performed on a plurality of the data sets to determine the production outcome of employing the data set in a stimulation job. The results of the simulation are used to determine the optimized data set for the stimulation job.

  • Patent number: 10899959
    Abstract: A method for improving the performance of fracturing processes in oil production fields may rely on polymer coated particles carried in the fracturing fluid. The particles may include heavy substrates, such as sand, ceramic sand, or the like coated with polymers selected to absorb water, increasing the area and volume to travel more readily with the flow of fluid without settling out, or allowing the substrate to settle out. Ultimately, the substrate may become lodged in the fissures formed by the pressure or hydraulic fracturing, resulting in propping open of the fissures for improved productivity.
