The sensor assemblies may be coupled to a casing string (e.g., the exterior of the casing), and detect RFID tags or other properties of material (e.g., fluids) in an annulus surrounding the casing string. During cementing or other operations, RFID tags may be used to track fluids. RFID detection circuits may be used to scan at different frequencies, and corresponding results may be compared by various means and processes to determine the presence of RFID tags.

  • Patent number: 10301929
    Abstract: A method and logging tool for evaluating leakage within a wellbore. In an embodiment, a percussive hammer assembly is selectively actuated to strike the interior wall of a casing, thereby propagating a sound wave along the casing. An array of acoustic detectors are selectively recorded during short time windows based on sound propagation times from the percussive hammer assembly to each acoustic detector, thereby avoiding the need to continuously sample acoustic detectors and collecting voluminous data. A self-tuning mode may be provided to determine sound propagation times.

  • Patent number: 10274625
    Abstract: A method is described for porosity mapping of low porosity subsurface reservoirs using seismic data and well logs. The method may compute dry-frame rock properties using fluid substitution modeling based on the well log data; perform porosity expansion of the dry-frame rock properties based on rock physics to generate expanded rock properties; generate synthetic seismic data based on the expanded rock properties; calibrate the seismic dataset with the synthetic seismic data; generate an estimated porosity map based on the calibrated seismic dataset and the synthetic seismic data; and identify geologic features based on the estimated porosity map. The method may be executed by a computer system.

  • Patent number: 10197702
    Abstract: Methods of forming a geologic map usable for identifying prospective resource accumulations beneath the earth-surface are disclosed herein. The methods include obtaining a seismic stratigraphic structure of a subsurface region of the earth, determining a plurality of potential resistivity boundaries from the seismic stratigraphic structure, obtaining an electromagnetic data set resulting from an electromagnetic data acquisition of the subsurface region, recovering a resistivity map of the subsurface region by performing an inversion process guided by the seismic information, and resolving a geologic map from the resistivity map.

  • Patent number: 10168447
    Abstract: A method, apparatus, and computer-readable medium provide automatic geosteering by automatically updating a geosteering structure model based upon observed data gathered during a drilling operation. In some embodiments, automatic updates may be used to introduce vertical shifts into a geosteering structure model to match synthetic log data with observed log data. In addition, in some embodiments an evolutionary algorithm may be used to introduce such vertical shifts and thereby provide an optimal match between the synthetic and observed log data.

  • Patent number: 10167703
    Abstract: Information associated with a plurality of constraints for well placement is received. For each of the plurality of constraints, information associated with the constraint is converted into a binary matrix. An overall constraint matrix is determined by convolving the binary matrices associated with the plurality of constraints. Feasible regions are determined based on the overall constraint matrix. Optimal well locations are determined within the feasible regions. The optimal well locations and a number of the optimal wells are output.

  • Patent number: 10162081
    Abstract: Systems, devices and methods for evaluating a volume of interest of an earth formation. The method may include modeling the volume as being in one of two states using a plurality of measurements corresponding to a plurality of measurement types, and may include assigning a relative credence indicator value to each measurement in dependence upon the corresponding measurement value and using the relative credence indicator value for each of the plurality of measurements to estimate the state of the volume by estimating the state of the volume using a state indicator value derived from the relative credence indicator values. The first state of the two states may correspond with presence of a condition associated with the formation, and the second state of the two states may correspond with absence of the condition. The condition may comprise presence of a fluid in the formation having a selected fluid type.

  • Patent number: 10156138
    Abstract: A method for collecting a formation fluid for testing includes introducing a formation sample tool having a first port and a second port into a wellbore. A first fluid is injected through the first port into the formation to clear a sample passage and allow access to uncontaminated formation fluid. A second fluid is injected through the second port into the formation to provide a barrier adjacent to or around the sample passage. A sample of the uncontaminated formation fluid is removed from the formation through the first port.

  • Patent number: 10132128
    Abstract: Methods, computing systems, and computer-readable media for removing fluid from a structure. The system may include sensors disposed within the structure (such as a multi-lateral well) that measure properties of the fluid at the location of the sensors and generate data representing the properties. A computing system receives the data and, using the data, monitors the composition of the fluid at the locations of the sensors. The computing system also displays information about the composition of the fluid at the locations of the sensors. The computing system may, in response to a change in the composition, indicate that the removal process is complete for a particular section and stop the flow for that section.

  • Patent number: 10114142
    Abstract: Systems and methods are provided for investigating a downhole formation using a nuclear magnetic resonance (NMR) tool having two or more radio frequency receiving coils. While the tool is moving through the borehole, the formation is magnetized and resulting signals are obtained. In accordance with the present approach, the acquired signals can be resolved azimuthally and can be reconstructed to obtain an indication of a parameter of the formation at multiple locations along the length of the borehole.

  • Patent number: 10113411
    Abstract: The present disclosure introduces methods and apparatus for acquiring a borehole image corresponding to a sidewall surface of a borehole that penetrates a subterranean formation, wherein the subterranean formation comprises structural elements and a varying geophysical characteristic. The borehole image comprises structure corresponding to the structural elements, texture corresponding to the varying geophysical characteristic, and coverage gaps (605) in which the structure and texture are missing. Trends corresponding to the structure are extracted from the borehole image. Missing structure within the gaps (605) is reconstructed based on the extracted trends. Missing texture within the gaps is simulated based on the borehole image and the reconstructed structure. A fullbore image is constructed based on the borehole image, the reconstructed structure within the gaps, and the simulated texture within the gaps.
