A tubular joint for a well string includes an elongated tube that includes an inner surface and an outer surface; a thrusting element affixed to the inner surface of the tubular joint; and a landing pad disposed along the tubular joint, the landing pad secured to the thrusting element by a spring. The landing pad is configured to move outward from the outer surface relative to the thrusting element.

Tubing with selective activated landing profile for well completion

A downhole robotic fishing tool includes a main body configured to be positioned in a wellbore and an intermediate body connected to a downhole end of the main body by an upper articulating joint. A robotic hand is connected to a downhole end of the intermediate body by a lower articulating joint. The robotic hand is configurable between an open configuration and a closed configuration and includes a palm, a robotic thumb and a robotic finger attached at their respective proximal ends to the palm in opposition. When in the closed configuration, the distal ends of the thumb and finger are within a grasp center area centered on a center point defined by an intersection of a grasping axis and an opposition axis of the robotic hand. A camera is positioned on the palm that has an optical axis that intersects the grasp center area proximate the center point.

A method may include obtaining caliper log data regarding a well. The method may further include determining, using a descaling model and the caliper log data, various predicted caliper log values for a descaled well. The descaled well may correspond to the well following a scale treatment. The method may further include determining whether the descaled well satisfies a predetermined criterion based on the predicted caliper log values. The method may further include determining, in response to determining that the descaled well fails to satisfy the predetermined criterion, a tubular replacement for the well. The method may further include transmitting, to a control system, a command that implements the tubular replacement.

Method and system for predicting caliper log data for descaled wells

A method for performing a maintenance operation of a well in an oil/gas field. The method includes identifying an extent of corrosion deposit of the well, predicting, using a descaling model of the oil/gas field and based on the extent of corrosion deposit, expected descaling metal loss in a tubular of the well, calculating, based on the expected descaling metal loss, a tubular burst/collapse pressure for a predicted thickness of the tubular, comparing the tubular burst/collapse pressure against a well operating pressure to generate a comparison result, and performing the maintenance operation of the well based on the comparison result.

Well tubing/casing corrosion deposits descaling model

The well system includes a casing and production tubing and a control unit that can receive measurements of temperature and pressure of fluid in the tubing-casing annulus (TCA). A subsurface safety valve (SSSV) connected to the tubing can switch to an open or closed state in response to a change in pressure of the fluid. An expected thermal expansion or contraction of the TCA fluid is calculated based on the received measurements, and the control unit determines, based on the expected thermal expansion or contraction and on a calculated TCA volume, a volume necessary to be added to or released from the TCA to maintain the fluid within an optimal pressure range. The control unit can also receive an indication of an emergency condition and transmit a signal to activate a release valve to release from the TCA a volume of fluid sufficient to cause the SSSV to close.

Subsurface safety valve system and method

The present disclosure describes methods and systems, including computer-implemented methods, computer program products, and computer systems, for predicting casing leaks. One computer-implemented method includes obtaining raw electromagnetic (EM) corrosion data for a hotspot, wherein the raw EM corrosion data includes a metal thickness loss value for the hotspot; determining a corrosion parameter based on the raw EM corrosion data; generating a probability distribution curve for the corrosion parameter; generating a corrosion severity classification matrix based on the probability distribution curve, wherein the corrosion severity classification matrix includes a plurality of corrosion severity classes and cutoff values for each of the plurality of corrosion severity classes; and assigning the hotspot into one of the plurality of corrosion severity classes based on the corrosion severity classification matrix and the corrosion parameter of the hotspot.
