Patent number: 11473425Abstract: Systems and methods of surface logging a well use a plurality of polymeric taggants distinguishable from each other. The systems and methods can include adding each of the plurality of polymeric taggants in a repeating sequence to a circulating drilling fluid while drilling the well and taking a sample drill cuttings carried by the circulating drilling fluid. The systems and methods can also include measuring concentrations of individual polymeric taggants attached to the drill cuttings in the sample and identifying a depth associated with the sample based on the measured concentrations of individual polymeric taggants and on the sequence.Type: GrantFiled: September 15, 2020Date of Patent: October 18, 2022Assignee: Saudi Arabian Oil CompanyInventors: Hooisweng Ow, Jason R.

Patent number: 11112525Abstract: Nuclear magnetic resonance (NMR) well logs are obtained from a well in the reservoir measures of the total fluid, including both water and hydrocarbon, in the shale of the reservoir. NMR measurement at the surface of shale subsurface samples obtained in the form of drill cuttings or core samples from the same well provide measures of total water content of the shale. At the surface, pressure on the subsurface sample becomes that of atmospheric pressure, and hydrocarbon gas contained in the shale cuttings bleeds off. The remaining fluid within the shale cuttings is then only water, which can be measured using NMR techniques. Compensation for the effect of drilling fluids (drilling mud) on the NMR measures from the fluid cuttings is also performed. The hydrocarbon gas content of the formation shale can be determined from the difference between formation NMR well log readings and NMR measurements from subsurface sample.Type: GrantFiled: December 17, 2019Date of Patent: September 7, 2021Assignee: Saudi Arabian Oil CompanyInventors: Jinhong Chen, Stacey M Althaus, Daniel T Georgi, Hui-Hai Liu

Patent number: 10920556Abstract: The present disclosure describes methods and systems for fracturing geological formations in a hydrocarbon reservoir. One method includes forming a borehole in a hydrocarbon reservoir from a surface of the hydrocarbon reservoir extending downward into the hydrocarbon reservoir; transmitting an electromagnetic (EM) wave through the borehole; directing at least a portion of the EM wave to rocks at a location below the surface in the hydrocarbon reservoir; and fracturing the rocks at the location below the surface in the hydrocarbon reservoir by irradiating the rocks around the borehole using at least the portion of the EM wave, where the irradiating is performed by irradiating a first portion of the rocks by using the EM wave for a first duration and after irradiating the first portion of the rocks for the first duration, refraining from irradiating the first portion of the rocks for a second duration.Type: GrantFiled: May 26, 2020Date of Patent: February 16, 2021Assignee: Saudi Arabian Oil ComoanvInventors: Jinhong Chen, Daniel T.

Patent number: 10845292Abstract: A method for correcting low permeability laboratory measurements for leaks. A pulse-decay permeability (PDP) experiment is performed on a core sample retrieved from a formation. The PDP experiment includes flowing fluid through the core sample in a sealed enclosure. In response to flowing the fluid through the core sample, a change in fluid pressure is measured over time. Based on the change in fluid pressure over time, a leakage of fluid from the sealed enclosure is determined. In response to determining the leakage of fluid from the sealed enclosure, an analytical model of the leakage is determined based on the change in fluid pressure over time.Type: GrantFiled: June 5, 2018Date of Patent: November 24, 2020Assignee: Saudi Arabian Oil CompanyInventors: Daniel T.

Patent number: 10808529Abstract: A method for surface logging a well uses a plurality of polymeric taggants distinguishable from each other. The method includes selecting the polymeric taggants that have ceiling temperatures that do not interfere with pyrograms from source rock decomposition and adding each of the plurality of polymeric taggants to a circulating drilling fluid in a sequence while drilling the well. A sample of drill cuttings carried by the circulating drilling fluid is then taken. The method also includes measuring, using pyrolysis-gas chromatographymass spectrometry, concentrations of individual polymeric taggants attached to the drill cuttings in the sample and analyzing, using pyrolysis-gas chromatographymass spectrometry, properties of the drill cuttings. A depth associated with the sample is identified based, at least in part, on the measured concentrations of individual polymeric taggants and on the sequence.Type: GrantFiled: October 15, 2018Date of Patent: October 20, 2020Assignee: Saudi Arabian Oil CompanyInventors: Hooisweng Ow, Jason R.
