    Abstract: A downhole tool actuator (100) includes a housing (102) defining an axial bore and a first port (110) extending radially from the axial bore, as well as a piston (106) disposed and movable within the axial bore of the housing. The piston (106) includes a receptacle wall (116), a shaft (126) extending axially from the receptacle wall, and a contact member (130) extending across the shaft. The receptacle wall (116) defines a chamber (118) and a second port (120) extending radially from the chamber. The contact member (130) is positioned outside of the housing (102) and is configured to engage a downhole tool.

    Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including: receiving a real-time density log comprising bulk density readings of a subterranean formation, where a well is being drilled in the subterranean formation; aggregating density readings over a first threshold distance from a current drilling depth in the subterranean formation; calculating a minimum formation density and a maximum formation density in the aggregated density readings; calculating a difference between the maximum formation density and the minimum formation density; in response to determining that the difference is greater than a field threshold, determining whether a previous kick alert occurred at least a second threshold distance from the current drilling depth; and in response to determining that the previous kick alert occurred at least the second threshold distance from the current drilling depth, detecting a kick in the well.

    Abstract: The present invention relates to a subsea PLET (1) with an upstream flow jumper connection (20). The PLET includes a bypass valve (27) and a valve (26) of each of a pump inlet and a pump outlet, each in fluid connection with a pipeline (24). At least one pump module coupling (21) is in fluid connection with the valve (26) of each of the pump inlet and pump outlet. At least one pump module guiding means enables guiding of a pump module onto the subsea PLET (1).

    Abstract: Systems and methods for evaluating simulation models are disclosed. In one embodiment, a method of evaluating a simulation model of a hydrocarbon field includes merging simulated reservoir data and actual reservoir data to generate merged reservoir data, and cross-linking the merged reservoir data with three-dimensional model data. The method further includes calculating one or more surface metrics from at least one of the merged reservoir data and the three-dimensional model data, calculating one or more subsurface metrics from at least one of the merged reservoir data and the three-dimensional model data, and calculating one or more overall history match indicators, one more surface history match indicators, and one or more subsurface history match indicators from the one or more surface metrics, the one or more subsurface metrics, and the three-dimensional model data.
