摘要： A method for obtaining geological heterogeneity trends of a geological formation, including the steps: drilling wells (w1, w2, w3, w4, w5) that penetrate the formation, acquiring well logs (log 1, log 2) for each well (w1, w2, w3, w4, w5) as function of depth inter Vals (Dk) of the respective well, determining a third degree tensor (Tk, m, n), where a z-dimension denotes the depths, a x-dimension denotes the well logs, and a y-dimension denotes the wells, extracting matrices (L1k,m, L2k,m, . . . , LMk,n) from the tensor (Tk, m, n), clustering the matrices (L1k,n, L2k,n, . . . , LMk,n) based on the characteristics of the corresponding well logs (log 1, log 2) to a clustering result matrix, aggregating the clustering result matrix to a cluster ensemble (π1, π2, . . . , πM), and spatial partitioning the cluster ensemble (π1, π2, . . . , πM) to a map that shows the geological heterogeneity trends associated with cluster types of the wells (w1, w2, w3, w4, w5).

摘要： A precise deep oil and gas navigation system based on structural evaluation of a sand/shale formation, and a device are provided. The precise deep oil and gas navigation system is implemented by: acquiring basic data of a target well location as well as basic data and an acoustic LWD curve of an adjacent well; dividing a basic data group; retaining extremely strongly correlated data and strongly correlated data of the basic data group, and performing dimensionality reduction; constructing a three-dimensional fusion feature data volume based on a dimensionality-reduced fusion feature parameter and a time-frequency spectrum; predicting a missing curve according to the three-dimensional fusion feature data volume; and correcting a stratigraphic structure model based on the missing curve to guide the design of a drilling trajectory.

摘要： A system and method that include receiving an oilfield operational plan and converting the oilfield operational plan into pixel-grids that are interpreted as images. The system and method also include inputting the pixel-grids to an image analysis convolution neural network to execute an image interpretation process. The system and method additionally include determining a current state of the oilfield operational plan based on the image interpretation process. The system and method further include determining a next state of the oilfield operational plan.

摘要： A system for drilling a well may be adapted to process signals received from a fiber optic cable located in the casing of a previously drilled well or wells. The fiber optic cable may act as a distributed sensor receiving acoustic signals generated during the drilling of the well, and the system may be programmed to process the signals from the fiber optic cable to locate the borehole of the well being drilled, including its location relative to the previously drilled well or well. The system may be used to automatically update a well plan for the well being drilled responsive to information about the location of the borehole and also may be used to automatically adjust one or more drilling parameters or drilling operations responsive to the location of the second well borehole.

摘要： An apparatus for estimating a first property in a borehole penetrating the earth is described. The apparatus includes a carrier configured to be conveyed through the borehole. The apparatus also includes a first sensor disposed at the carrier and configured to perform a first measurement of the first property, the first sensor having a first direction of sensitivity; a second sensor disposed at the carrier and configured to perform a second measurement of a second property, the second sensor having a second direction of sensitivity; and a processor configured to receive the first and second measurements and to correct the first measurement using the second measurement in order to estimate the first property.

摘要： Methods, systems, and non-transitory computer readable media for identifying type curve regions as a function of position in a region of interest are disclosed. Exemplary implementations may include: obtaining a spatial clustering model from the non-transitory storage medium; obtaining well data from the non-transitory storage medium; obtaining production parameter data from the non-transitory storage medium; and delineating each of the type curve regions in the region of interest by applying the spatial clustering model to the well data and the production parameter data.

摘要： A mobile plant for orienting a tool with respect to a hole is provided. The plant includes an arm assembly for supporting a tool wherein the tool is adapted to be lowered into the hole. The plant also includes a primary sensor for sensing the geographical location of the tool, and a secondary sensor for sensing the location and/or orientation of the hole. In use, the plant adjusts the position of the tool supported by the arm assembly based on the geographical location sensed by the primary sensor and the location and/or orientation sensed by the secondary sensor, in order to align the tool supported by the arm assembly with the hole.

摘要： A geological exploration method starts by obtaining measurements and calculating properties along boreholes in an area of interest to generate log data including plural curves. Anomalies are detected along at least one curve of one of the boreholes. A machine learning regressor is trained using one or more curves without anomaly values of the one of the boreholes and/or of another similar borehole among the boreholes, to predict a synthetic curve corresponding to the at least one curve. The synthetic curve is then blended into the at least one curve.
