摘要： A method is performed for defining optimal landing location(s) of horizontal wells for hydraulic fracturing stimulation, for improved well performance of unconventional reservoirs. The method includes evaluating one or more planes of weakness, pinch-out points, or thin rock layering in the reservoir that may impede hydraulic fracture growth or may close fractured sections during production. The method can include conducting detailed analysis on core and open hole logs, and defining the presence, density, orientation, spacing, and mechanical properties of various thin interfaces and barriers in the rock mass. The method can include classifying the barriers or thin interfaces based on their effect on hydraulic fracture growth or fracture connectivity, and on uncertainty of their effect.

摘要： A variable-frequency light source is configured to emit a light beam and modulate a frequency of the light beam. A fiber optic cable is attached to the variable frequency light source. The fiber optic cable is configured to receive the light beam at an inlet and pass the light beam to an exit. Multiple optical detectors are attached to the fiber optic cable. Each of the optical detectors is configured to detect a specified frequency of light that is backscattered through the fiber optic cable. An actuation mechanism is attached to the fiber optic cable. The actuation mechanism is configured to deform the fiber optic cable in response to a stimulus.

摘要： A method for includes obtaining a well log comprising a sequence of measurements of a wellbore in a field, and generating change points in the well log based on the sequence of measurements. Each of the change points corresponds to a depth along the wellbore where a probability distribution of the well log changes. The method further includes generating a statistic for each of multiple intervals in the well log, where the intervals are defined by the plurality of change points, categorizing the intervals based on the statistic for each of the intervals to generate categorized intervals, and performing the operation based on the categorized intervals.

摘要： A method for equitable allocation of hydrocarbon component yields which uses the output of process modeling of the hydrocarbon processing system with the individual source streams commingled into a single inlet stream to create a differential value table which can be used to provide the allocation of output product to the individual source streams that are accountable for the individual component yield.
