Publication number: 20180364142Abstract: 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: ApplicationFiled: June 5, 2018Publication date: December 20, 2018Applicant: Saudi Arabian Oil CompanyInventors: Daniel T.

Publication number: 20180081077Abstract: Measures of the hydrocarbon content of a shale gas formation or reservoir are obtained. 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: ApplicationFiled: September 16, 2016Publication date: March 22, 2018Inventors: Jinhong Chen, Stacey M.
