摘要： Drill collars may be constructed using solid-state welding processes. Solid-state welding produces robust drill collars with high fatigue lifespans and permits individual segments of the drill collar to be optimized based on their intended use. A drill collar may be formed of a first segment with a different material, density, modulus of elasticity and/or geometry than an adjacent second segment fused thereto. If a segment of a drill collar is damaged in use, the damaged segment may be removed and replaced, possibly without de-rating the drill collar. Methods of forming the solid-state welds may include friction welding adjacent segments to one another such that features in each segment are circumferentially aligned when the weld is formed. Supplemental energy sources may provide additional heat at the welded surfaces to ensure the segments are effectively fused.

摘要： A method of determining the depth of a sidewall core sample taken from a borehole relative to a reference log of the borehole. The method includes obtaining a reference log recorded on a reference log depth scale and a borehole image log recorded on a borehole image log depth scale of a portion of the borehole from which the sidewall core sample has been taken. The method further includes generating a calibrated borehole image log from the borehole image log and the reference log and identifying a candidate sidewall core image artifact in the calibrated borehole image log. The method also includes assigning a confidence value for the candidate sidewall core image artifact based on a characteristic of the candidate sidewall core image artifact, and determining, using the confidence value, a probability that the sidewall core sample was collected at a certain depth on the reference log depth scale.

摘要： Methods for machine learning-based differencing for hydrocarbon well logs are disclosed. A computer system generates an input layer of a machine learning module. The input layer includes a graphical representation of datasets obtained from one or more hydrocarbon wells. The computer system generates an encoding layer of the machine learning module from the graphical representation. The encoding layer includes a two-dimensional array based on the multiple datasets and a merged dataset of the one or more hydrocarbon wells. The computer system determines that a difference between a first hydrocarbon well log of the multiple datasets and a second hydrocarbon well log of the merged dataset warrants an action. The determining is performed using a convolutional layer. Responsive to determining that the difference warrants an action, the computer system performs the action on the first hydrocarbon well log and the second hydrocarbon well log to modify the merged dataset.

摘要： An apparatus for in-line mud logging is adapted to be in material communication with a conveyor used for conveying drilling fluid and/or drill cuttings from a well. An analysis body, disposed in the path of material falling from the conveyor has a sample accumulation tray for collecting a sample of material falling from the conveyor, and a gamma-ray detector for acquiring gamma-ray spectra from the sample of material. A weight sensor detects weight of the sample of material. A sample removal device is used to remove the sample of material from the sample accumulation tray after a desired sample interval. Signals from the gamma-ray detector and the weight sensor are communicated to a control unit.

摘要： Methods of using capture gamma-ray spectroscopy for analyzing gravel-packs, frac-packs, and cement are disclosed herein. The methods can include distinguishing particles placed in a borehole region from particles placed in a subterranean formation outside of the borehole region, by utilizing a slurry comprising a liquid, particles, and a thermal neutron absorbing material to place the particles into the borehole region. The methods can also include obtaining first and second data sets by lowering into a borehole traversing the borehole region a pulsed neutron logging tool comprising a pulsed neutron source and a detector, emitting pulses of neutrons from the pulsed neutron source into the borehole region at intervals of one pulse per about 1,000 µsec for the first data set and about one pulse per about 100 µsec for the second data set, and detecting capture gamma rays resulting from nuclear reactions in the borehole and the subterranean formation.
