Abstract:
Embodiments of the present disclosure are directed to embodiments of synthetic functionalized additives. The synthetic functionalized additive may include a layered magnesium silicate. The layered magnesium silicate may include a first functionalized silicate layer including a first tetrahedral silicate layer covalently bonded to at least two different functional groups, an octahedral brucite layer, including magnesium, and a second functionalized silicate layer including a second tetrahedral silicate layer covalently bonded to at least two different functional groups. The octahedral brucite layer may be positioned between the first functionalized silicate layer and the second functionalized silicate layer. The at least two different functional groups covalently bonded to the first tetrahedral silicate layer may be the same or different than the at least two different functional groups covalently bonded to the second tetrahedral silicate layer.
Abstract:
In some embodiments, input seismic data is decomposed into Gaussian beams using plane wave destructor (PWD) filters. The beams are used in a fast beam migration method to generate a seismic image of a subsurface volume of interest. PWD filters are applied to groups of neighboring traces to generate a field of dips/curvatures that fit the input trace data. Beam wavelets are then formed according to the dip/curvature field. Multiple dips (PWD slopes) may be determined at each location in time/space in order to handle intersecting reflection events. Exemplary methods allow an improvement in processing speed by more than an order of magnitude as compared to standard industry techniques such as Kirchhoff migration.
Abstract:
An automated testing apparatus for remotely performing a testing sequence to ensure that a sensor is functioning. The apparatus can include a detector, a storage container, a burst valve in fluid communication with the storage container, a testing control module in communication with the storage container and the burst valve, and a remote user interface remotely located from the detector. Preferably, the automated testing apparatus can simplify the testing procedure, increase the frequency of sensor testings, thereby notifying operations of sensor failures in a more timely fashion without the need for an operator to check the sensor locally.
Abstract:
A method of identifying a bed boundary in a subterranean formation by processing data measured by an induction logging tool. An interferometric method compares recorded voltages and/or phases recorded at axially spaced apart receivers on the logging tool. A transmitter is on the logging tool and set between the receivers, where the receivers are equally spaced apart from the transmitter. The transmitter emits a signal having frequencies up to around 50 kHz.
Abstract:
A hybrid wired and wireless architecture for a process control system is disclosed that includes hierarchical adaptability and optimization capabilities. The system is arranged in three tiers, the first including a number of wireless end devices exchanging packets of data and/or instructions with the distributed control system, where each wireless end device is associated with one or more meters, remote terminal units, diagnostic devices, pumps, valves, sensors, or tank level measuring devices. The second tier includes a plurality of wireless routers, each including a memory that stores a routing table and a processor that routes packets. The third tier includes a master wireless gateway device operably connected to receive packets from and transmit packets to the distributed control system. The processor of each of the wireless routers routes packets across the tiers between the end devices and the wireless gateway devices based on the stored routing table.

Abstract:
A system may include a wellbore extending a first depth into a formation. Additionally, a cured-in-place pipe liner may be coupled to walls of the wellbore. One or more fiber optic cables are embedded in the cured-in-place pipe liner to monitor a curing of the cured-in-place pipe liner and record well data. The one or more fiber optic cables may be used to continuously monitor the wellbore during a method for lining the wellbore is performed. The method for lining the wellbore may include inserting the cured-in-place pipe liner into the wellbore; forcing the cured-in-place pipe liner against walls of the wellbore; curing the cured-in-place pipe liner; monitoring the curing of the cured-in-place pipe liner with the one or more fiber optic cables embedded in the cured-in-place pipe liner; and coupling the cured-in-place pipe liner to the walls of the wellbore.
Abstract:
A method may include obtaining a petrographic image. The method may further include determining various region proposals based on the petrographic image and a selective searching function. A respective region proposal among the region proposals may correspond to various pixels in the petrographic image according to a predetermined dimension. The method may further include determining color histogram data for the petrographic image. The method may further include determining input image data based on the petrographic image, the region proposals, and the color histogram data. The method may further include determining a rock object using the input image data and a machine-learning model.
Abstract:
Methods and systems are disclosed. The methods may include obtaining vertical seismic profile (VSP) data and a seismic velocity model for a subterranean region of interest and determining, using the seismic velocity model and reverse time migration, a pre-stacked migrated seismic image based on the VSP data. The pre-stacked migrated seismic image includes seismic slices. The methods may further include, for each of the seismic slices in turn, determining a coherency map, determining a weighting map based on the coherency map, and determining a corrected seismic slice by applying the weighting map to each of the seismic slices. The methods may still further include determining a post-stacked corrected migrated seismic image based on the corrected seismic slices and determining a location of a geological feature within the subterranean region of interest based, at least in part, on the post-stacked corrected migrated seismic image.

An untethered device includes a tool and a ballast weight. The ballast weight includes an attachment plate that is securable to the tool, a dissolvable ballast, and attachment elements that secure the dissolvable ballast to the attachment plate. At least one of the attachment elements is dissolvable to release the dissolvable ballast from the attachment plate.
