Publication number: 20250027404Abstract: Described is a polymer-based well tracer. The polymer-based well tracer is a fluoropolymer having a fluorinated group. The fluoropolymer may be formed into a particle, a coating for proppant particulates, or encapsulated in a polymeric resin. Upon degradation or hydrolysis of the fluoropolymer, the fluorinated group having a fluorinated compound is released within the well.Type: ApplicationFiled: October 1, 2024Publication date: January 23, 2025Applicant: ARAMCO SERVICES COMPANYInventors: Rajesh Kumar Saini, Amy J. Cairns, Shitong Sherry Zhu, Ayrat Gizzatov, Wei Wang, Mohammed Sayed, Hooisweng Ow

Patent number: 12116528Abstract: Unconventional hydrocarbon source rock reservoirs can contain the organic material kerogen, intertwined with the rock matrix. The kerogen can alter the tensile strength of the rock and contribute to higher fracture energy needs. To degrade kerogen and other organic materials, oxidizing gasses are dissolved in carbon dioxide (CO2) which is then used as part of a fracturing fluid. The oxidizing gasses can be dissolved directly in the CO2 or generated in situ using precursors.Type: GrantFiled: June 9, 2023Date of Patent: October 15, 2024Assignee: Saudi Arabian Oil CompanyInventors: Desmond Schipper, Katherine Leigh Hull, Rajesh Kumar Saini, Younane N.

Publication number: 20240318545Abstract: A method includes introducing a fluoro-based small molecule tracer into a stimulation fluid, injecting the stimulation fluid into a target zone of a subterranean formation, and maintaining the fluoro-based small molecule tracer inside the target zone of the subterranean formation for an amount of time. While being maintained inside the target zone, the fluoro-based small molecule tracer comes into contact with water at a downhole temperature resulting in hydrolysis of the fluoro-based small molecule tracer to produce a fluorinated tracer and a nonfluorinated group. Then, produced fluid that includes the fluorinated tracer is recovered, a concentration of the fluorinated tracer in the hydrocarbons is determined, and the concentration of the fluorinated tracer is correlated to a productivity of the target zone of the subterranean formation.Type: ApplicationFiled: May 31, 2024Publication date: September 26, 2024Applicant: SAUDI ARABIAN OIL COMPANYInventors: Rajesh Kumar Saini, Amy J.

Publication number: 20240209729Abstract: A method for monitoring gas production in a subterranean formation includes introducing a polymer composite particle having a degradable portion and a non-degradable portion including a tracer into a stimulation fluid and injecting the stimulation fluid into the subterranean formation to a treatment stage of a treatment zone. The treatment stage has at least one opening that the polymer composite particle may flow into and remain inside. The polymer composite particle may be exposed to moisture at a downhole temperature while inside the at least one opening. The moisture may degrade the degradable portion of the polymer composite particle, thereby releasing the non-degradable portion including the tracer. Produced gas that includes the non-degradable portion including the tracer may be recovered from the subterranean formation and the tracer may be correlated to the treatment stage of the treatment zone of the subterranean formation.Type: ApplicationFiled: March 6, 2024Publication date: June 27, 2024Applicant: SAUDI ARABIAN OIL COMPANYInventors: Ayrat Gizzatov, Shitong Sherry Zhu, Amy J.
