摘要： Method and device for determining permeability as a function of pore pressure and porosity of a subsurface formation. The method includes positioning a sample (30) in a sample assembly inside a pressure vessel (50) comprising gas or liquid and a pressure gauge (34) measuring a first gas pressure of the sample in the pressure vessel (50), applying a second gas pressure to the pressure vessel (50), the second gas pressure being greater than the first gas pressure, measuring a third gas pressure at time at location from the inlet (16) of sample inside the pressure vessel (50), determining a total gas mass per unit volume of the subsurface formation and determining the permeability of the subsurface formation as a function of pore pressure based at least in part on the first gas pressure, the second pressure, the third gas pressure, and the gas density, with a single test run.

摘要： A compressive load is exerted with a test apparatus across a rock sample that has a specified length-to-diameter ratio. A strain on the rock sample is measured during the compressive loading with a strain gauge. A mechanical property of the rock sample is determined based at least in part on the compressive load. An elastic property of the rock sample is determined based at least in part on the measured strain and the compressive load.

摘要： The present invention relates to methods for analyzing and modeling natural gas flow in subterranean shale reservoirs. In preferred embodiments, methodologies and techniques for determining and modeling natural gas flow in shale formations using methodologies and techniques capable of determining natural gas properties related to dual-continuum flow, permeability and pressure within a subterranean shale reservoir. In some embodiments, the natural gas properties are determined by subjecting a subterranean shale reservoir sample to pulse-decay analysis. In certain embodiments, the methodologies and techniques described herein may be used in various reservoirs exhibiting macroporosity and/or microporosity, such as fractured reservoirs and carbonate reservoirs composed of reservoir fluids.

摘要： Techniques for hydraulically fracturing a geologic formation include circulating a proppant-free hydraulic fracturing liquid into a wellbore that is formed from a terranean surface into a geologic formation within a subterranean zone that is adjacent the wellbore; fluidly contacting the geologic formation with the proppant-free hydraulic fracturing liquid for a specified duration of time; and subsequent to the specified duration of time, circulating a hydraulic fracturing liquid that includes proppant into the wellbore to fracture the geologic formation.
