Publication number: 20240035373Abstract: 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: July 27, 2022Publication date: February 1, 2024Applicant: ARAMCO SERVICES COMPANYInventors: Ayrat Gizzatov, Shitong Sherry Zhu, Amy J. Cairns, Rajesh Kumar Saini, Mohammed Sayed, Wei Wang

Publication number: 20240035374Abstract: 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: July 27, 2022Publication date: February 1, 2024Applicant: ARAMCO SERVICES COMPANYInventors: Rajesh Kumar Saini, Amy J.

Patent number: 11697755Abstract: Degradable polymer additives are provided. The degradable polymer additives include a tracer functional group that is bonded to a base polymeric component by a hydrolysable covalent bond. The base polymeric component is a polysaccharide. The tracer functional group is selected from the group comprising a halogen-containing functional group, a substituted heterocyclic aromatic group, and combination thereof. A method utilizing the degradable polymeric additives in an altered drilling fluid is provided. Such a method includes introducing the altered drilling fluid into a wellbore and recovering an associated wellbore cutting from a depleted drilling fluid.Type: GrantFiled: July 14, 2021Date of Patent: July 11, 2023Assignees: ARAMCO SERVICES COMPANY, SAUDI ARABIAN OIL COMPANYInventors: Chengzhe Gao, Shitong Sherry Zhu, Marta Antoniv, Nouf AlJabri

Patent number: 11427742Abstract: A method of surface logging a well includes adding each of multiple polymeric taggants to a circulating drilling fluid in an addition sequence while drilling the well. Each polymeric taggant includes a polymer and a respective fluorescent dye having an emission wavelength or excitation wavelength different from that of each other fluorescent dye. The method includes taking a sample of drill cuttings carried by a drilling fluid while drilling a well, wherein the sample of drill cuttings includes polymeric taggants attached to the drill cuttings. The method includes extracting the dyes from the sample of drill cuttings into an extract solution; determining an indication of the type of and the concentration of each of the dyes in the extract solution; and determining a depth associated with the sample of drill cuttings based on the indication of the concentration of each of the dyes and on the addition sequence.Type: GrantFiled: August 24, 2020Date of Patent: August 30, 2022Assignee: Saudi Arabian Oil CompanyInventors: Nouf AlJabri, Alberto F. Marsala, Shitong Sherry Zhu, Marta Antoniv

Patent number: 11237295Abstract: A method for depth determination of drilled rock cuttings is disclosed. The taggant is injected and transported downhole along the mud stream and attaches to the rock cuttings. Taggant impregnated cuttings are detected at the surface based on molecular weight, emission wavelengths or radio frequency characteristics for encoding the taggant. The identification code identifies the depth of the drill bit when the particular batch of the taggant is released into the mud. The detection data, in addition to mud properties, flow rates, drill volume and penetration rates, formation characteristics, and well specifications are transferred to and analyzed by a taggant analysis and control engine. The taggant analysis and control engine controls an IoT controller that adapts the parameters of the taggant injection pump to achieve an intelligent controlled release to optimize the depth characterization process.Type: GrantFiled: October 13, 2020Date of Patent: February 1, 2022Assignee: SAUDI ARABIAN OIL COMPANYInventors: Klemens Katterbauer, Alberto Marsala, Nouf Jabri, Shitong Sherry Zhu, Martin E.
