摘要： 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, wherein irradiating the rocks elevates pore-water pressure in the rocks causing fracturing of the rocks.

摘要： 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.
摘要翻译：获得页岩气地层或储层的烃含量的测量值。核磁共振（NMR）测井曲线是从油藏中测量包括水和碳氢化合物在内的总流体储层中的一口井获得的。在钻井岩屑或来自同一井的岩心样品形式获得的页岩地下样品表面的NMR测量提供了页岩总含水量的测量。在地表上，地下样品上的压力变成大气压力，并且包含在页岩屑中的烃气体渗出。然后页岩岩屑中的剩余流体仅为水，可以使用NMR技术测量。钻井液（钻井泥浆）对液体岩屑的NMR测量的影响的补偿也被执行。形成页岩的烃气体含量可以根据地层NMR井测井读数与地下样品的NMR测量之间的差异来确定。

摘要： 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.
