The debris catch provides a strainer located downstream of a rotating control device (RCD) within a flow line. The strainer is located between the RCD and at least one protected component. The strainer limits the debris and other junk that flows to protected components located downstream of the strainer. A first sensor and a second sensor detect the pressure differential between a location before the strainer and at the strainer. The two sensors detect a clog in the strainer. The strainer is removable through an access outlet for clearing the clog and reinstalling a strainer for continued drilling operation. A purge valve located in the system also allows clearing of the strainer by releasing the debris through a purge outlet located on a pathway separate from the pathway to the protected component.

A process and device to create access to low gravity solids (LGS) of about 2 to 20 microns for removal from a fluid material/LGS emulsion having the steps of: flowing the emulsion into high pressure tubing; separating the emulsion into at least two high pressure streams; forcing the emulsion through high pressure nozzles at a terminus of each of the at least two high pressure tubing streams at a speed in the range of about 10 ft/sec to 200 ft/sec or at a force in a range of about 10 to 100 PSI; and colliding the streams of emulsion exiting the high pressure nozzle within a pressure drop chamber, wherein the pressure drop is in a range of about 5% to 50% of the back pressure of the nozzles; wherein a cavitation effect is realized from a collision force of the high pressure streams within the pressure drop chamber.

A method may include adding a dry carrier powder loaded with a liquid additive into a wellbore fluid, thereby releasing at least a portion of the liquid additive into the wellbore fluid; and pumping the wellbore fluid with the liquid additive therein into a wellbore.

A method including selecting image data of a mechanical mud separation machines (“MMSM”) to detect objects in an object flow and other operational conditions at the MMSM. The image data may be processed by a Deep Neural Network to identify objects in the object flow, operational parameters of the MMSM, and environmental conditions. Additional image data may be selected for additional processing based on the results of the analysis.

An apparatus that includes an upper skid including a first floor supporting a first plurality of mud circulation components; a first storage structure disposed below the first floor that receives a fluid exiting the first plurality of components; and a first plurality of fasteners carried on the upper skid. The apparatus also includes a lower skid that includes a second floor supports a second plurality of mud circulation components; a second storage structure disposed below the second floor that receives a fluid exiting the second plurality of components; and a second plurality of fasteners carried on the support structure that correspond to the first plurality of fasteners to couple the upper skid over the lower skid. In an exemplary embodiment, the upper skid is selectively detachable from the lower skid.

A method includes receiving training images representing a portion of a drilling rig over a first period of time, associating individual training images of the training images with times at which the individual training images were captured, determining a rig state at each of the times, classifying the individual training images based on the rig state at each of the times, training a machine learning model to identify rig state based on the classified training images, receiving additional images representing the portion of the drilling rig over a second period of time, and determining one or more rig states of the drilling rig during the second period of time using the machine learning model based on the additional images.

Systems and methods for extracting and analyzing formation fluids from solids circulated out of a subterranean formation are provided. In one embodiment, the methods comprise: providing a sample of formation solids that have been separated from a fluid circulated in at least a portion of a well bore penetrating a portion of a subterranean formation at a well site; performing a solvent extraction on the sample of formation solids using one or more solvents at an elevated pressure at the well site, wherein at least a portion of one or more formation fluids residing in the formation solids is extracted into the one or more solvents to produce an extracted fluid; and analyzing the extracted fluid at the well site to determine the composition of the extracted fluid.

A method includes taking at least one image of a plurality of returned rock fragments from a wellbore using a camera, analyzing the at least one image with an image analysis program to detect a caving in the plurality of returned rock fragments, constructing a model of the caving, and incorporating the model of the caving into a finite element geomechanics model of the wellbore using a meshing program to create an adjusted model of the wellbore.

A removable screen panel assembly for a vibratory screening machine for separating liquids and solids. The screen panel assembly includes a plate, a corrugated screen assembly supported by the plate, hook assemblies connected to opposite ends of the plate, and gaskets connected to the hook assemblies. A first hook assembly has a first end connected to a first end of the plate, a middle portion spaced above first apertures at the first end of the plate, and a second end parallel to the plate. The second end of the first hook assembly and the first end of the plate sandwich a first end of the corrugated screen assembly.

Apparatus and methods for performing subsea drilling operations. An example method may include receiving drilling fluid from a drilling fluid source at a first pressure by a pressure exchanger located within a subsea environment and receiving seawater from the subsea environment at a second pressure by the pressure exchanger to increase pressure of the drilling fluid within the pressure exchanger to a third pressure. The second and third pressures are substantially greater than the first pressure. The method may further include discharging the drilling fluid from the pressure exchanger into piping to communicate the drilling fluid to a drill forming a wellbore in a seabed and discharging the seawater from the pressure exchanger into the subsea environment.
