Abstract: A downhole sensor apparatus may include a structure securing a circuit board. The structure may be configured to be inserted into a recess in a tool on a drill string. The downhole sensor apparatus may include one or more sensors coupled to the circuit board and a cap over the structure. The downhole sensor apparatus may further include a data port electrically coupled to the circuit board and configured to transmit data from the sensors to an external device. The downhole sensor apparatus may include a threaded element configured to thread into complementary threads in the recess in the tool. The downhole sensor apparatus may be configured to operate in an idle condition. The downhole sensor apparatus may compare readings from at least two sensors to threshold downhole conditions and begin normal operation when the readings from the at least two sensors meet or exceed the threshold downhole conditions.

Abstract: Current profile of water (e.g., ocean) around a riser connected to a wellhead may be measured and used to determine integrated current load on the riser at any given moment in time. The integrated current load may be used to estimate the wellhead fatigue damage rate at that moment in time. The estimated wellhead fatigue damage rate may be used to make operational decisions for the well.

Abstract: Provided is a gauge mandrel, a sensing system, and a well system. The gauge mandrel, in one aspect, includes a housing having a length (Lt), the housing having a main section and an upset section extending outward from the main section, and a primary fluid passageway located in the main section of the housing and extending along the length (Lt). In accordance with this aspect, the primary fluid passageway includes an uphole tubing coupling having an uphole tubing coupling centerline (CLTU) and a downhole tubing coupling having a downhole tubing coupling centerline (CLTD). In further accordance with this aspect, the uphole tubing coupling centerline (CLTU) and the downhole tubing coupling centerline (CLTD) are offset from one another by a distance (DT). The gauge mandrel may further include a gauge cavity located in the upset section of the housing and extending along at least a portion of the length (Lt).

Abstract: An untethered downhole tool includes a first body, a second body, a logging sensor, a motor, and a controller. Each of the first and second bodies includes a housing that defines an inner volume and a magnetic anchor configured, in an active state, to attach the body to a wellbore tubular. The motor is attached to one of the first or second bodies and coupled to a spooler. The controller is communicably coupled to the motor and the first and second magnetic anchors. The controller is configured to adjust one of the first or second magnetic anchors from the active state to an inactive state; and activate the motor to operate the spooler to spool the cable from the spooler to increase a length of a portion of the cable between the spooler and the detached first or second body.

Abstract: A technique facilitates collecting data, related to a fracturing, run-in-hole, or pull-out-of hole operation. A frac plug is provided with electronics for obtaining the desired information related to the operation. For example, the frac plug may be constructed with electronic sensors, a digital storage device, and a power supply or other power related equipment. Depending on the application, the frac plug may be a composite frac plug, degradable frac plug, dummy frac plug, or other suitable frac plug. Retrieval of the information obtained may be done via coupling with an associated device, e.g. inductive or physical coupling, by utilizing a broadcast transmitter/receiver, by physical retrieval of the storage device, or by physical retrieval of the dummy frac plug.

Abstract: An assembly for use in subsurface drilling includes a downhole probe supported by a centralizer. The centralizer comprises a tubular member that extends around the downhole probe. A wall of the centralizer is fluted to provide inward contact points that support the downhole probe and outward contact points that bear against a bore wall of a section of drill string. The downhole probe may be supported for substantially its entire length.

Abstract: Systems and methods for obtaining a shape of a component within a subterranean well with an impression tool includes the impression tool having a top sub. The top sub is an elongated member having a central axis and a downhole facing surface. A threaded recess of the top sub extends axially from the downhole facing surface. A bottom body section has a block body, a lead impression block positioned at a downhole side of the block body, and a threaded member located at an uphole side of the block body. The threaded member of the bottom body section threadingly engages the threaded recess of the top sub. The bottom body section is operable to be selectively threaded to, and unthreaded from, the top sub.
