Abstract: The disclosure presents processes to generate look ahead data to guide borehole operations, such as drilling operations. The processes can array collected resistivity data around a representation of an active borehole. The array can be in various patterns, such as an interleaved helix pattern. Each slice of data from the collected resistivity data can be positioned and oriented corresponding to the central point depth parameter for each slice of data. A selection of one or more card views can be enabled to display details of the collected resistivity data corresponding to the selected slice of data. An analysis of the resistivity data can generate an identification of a boundary, such as an object or a subterranean formation change, in the subterranean formation look ahead portion of the active borehole. The boundary identification can be used as inputs to a borehole operation plan or to a geo-steering system.

Abstract: A coring tool includes a coring bit to cut and detach a core sample from a subsurface formation formed in a borehole. The coring tool includes a pressure vessel that includes a core chamber to store the core sample at a pressure and a piston positioned adjacent to the core chamber. The pressure vessel includes a chamber adjacent to the piston and a gas reservoir to store a gas that expands as the gas is moved to a surface of the borehole. The pressure vessel includes a valve coupled to an inlet of the chamber and an outlet of the gas reservoir, wherein the gas is to flow into the chamber when the valve is open to move the piston to cause an increase in the pressure of the core chamber.

The valve may be remotely reopened with fluid pressure form surface.

Abstract: A fiber optic cable positioned along a casing string in a wellbore may be calibrated by exciting a tube wave in the wellbore and detecting, by the fiber optic cable, a reflected tube wave. The reflected tube wave may correspond to a reflection of the tube wave off an obstacle within the wellbore. The obstacle may have a known location such that a reference point along the fiber optic cable may be associated with the known location of the obstacle for calibrating the fiber optic cable. Downhole applications utilizing data collected by the calibrated fiber optic cable, including location data, may weight the data collected based at least in part on an uncertainty value associated with a particular calibrated location along the length of the fiber optic cable.

Abstract: A variety of systems and methods are disclosed for cleaning a wellbore ahead of a well tool. The well tool is deployed on a tubular conveyance to a depth into a well. An interior surface of the well is wiped ahead of the well tool to dislodge debris from the interior surface of the well as the tubular conveyance advances downhole. The debris is filtered ahead of the well tool as the tubular conveyance advances downhole to keep the filtered debris away from the well tool. The well tool may then be used to perform a tool function when the tubular conveyance has reached the depth, without being affected by the filtered debris.

Abstract: Transmitting torque from a housing to a drive shaft by configuring contact surfaces between a housing and shaft to increase the transmission of torque. Tools such as drilling tools often require torque to be transmitted from a rotating housing to a driveshaft. This is often accomplished through threaded connections or splines. A threaded connection can be used to transmit torque by allowing two pieces to be securely joined by rotating and tightening to a specified torque. A splined connection can also be used to transmit torque, providing sufficient clearance for one member to slidingly receive the other without rotating and torqueing. A tapered polygon may be used to transmit torque that by virtue of tapering can take up clearances between the torque carrying components. As such, the tapered polygon does not introduce significant stress concentrations into the components.

Abstract: A frac sleeve system includes a well casing with a tubular wall having a frac port defined there through for hydraulic fracturing. A sleeve within the well casing includes a sleeve body. The sleeve is mounted for axial movement relative to the tubular wall of the well casing among three positions including: a closed position in which the sleeve body blocks the frac port, a frac position in which the sleeve body clears the frac port so the frac port is open for hydraulic fracturing there through, and a production position in which the sleeve at least partially blocks the frac port.

Abstract: Apparatus and method for passive gas separation in a through-tubing-conveyed (TTC) pump system comprise abruptly reversing a flow direction of wellbore fluids from flowing up the wellbore to down into a liquids reservoir. The generally annular liquids reservoir is formed between a production tubing and a pump of the TTC pump system. Wellbore fluids flowing up the production tubing are diverted into the annulus via one or more outlet ports in the production tubing. The wellbore fluids flow up the annulus until encountering one or more inlet ports in the production tubing, which redirects the wellbore fluids from the annulus down into the liquids reservoir. The reversal of flow direction causes gas in the wellbore fluids to separate from liquids as the gas continues moving up the wellbore instead of changing direction with the liquids. The substantially gas free liquids are then pumped by the pump up to the surface.

Abstract: An electrically-controlled, pin-pulling valve includes a pull pin (e.g., a pull piston) and a chemical propellant. The valve is configured to, using the pull pin and the chemical propellant, actuate from a closed position to an open position to activate a downhole tool. For instance, the pin-pulling valve may, based on an activation signal, activate the chemical propellant, which may cause the chemical propellant to react. The activation of the chemical propellant may cause the pull pin to withdraw from an extended position to a withdrawn position. The withdrawal of the pull pin may cause the pin-pulling valve to open, allowing hydraulic fluids to flow through a port associated with the downhole tool previously sealed by the pin-pulling valve. The flow of the hydraulic fluids may activate the downhole tool by exerting hydraulic pressure on the downhole tool.
