Abstract: A method for shutting off a wet interval of a wellbore includes producing hydrocarbons from a hydrocarbon bearing subterranean formation through a production string installed in the wellbore, identifying the wet interval of the wellbore, perforating the production string in the wet interval using an explosive-free punch tool to produce a plurality of openings in the production string, isolating the production string in the wet interval, treating the wet interval with a sealing composition injected through the plurality of openings into an annulus of the wellbore in the wet interval, and restoring a fluid flow path through the production string in the wet interval. The restored fluid flow path through the wet interval enables continued production of hydrocarbons from downhole intervals, while the sealing composition cured in the annulus provides a barrier to prevent fluid flow from the wet interval into the production string.

Abstract: A method of performing an intervention operation at a multilateral well includes deploying a directional guide to an axial position within the multilateral well at which a lateral section of the multilateral well is located. The method further includes installing a main body of the directional guide to an inner surface profile arranged along a casing that surrounds the directional guide at the axial position. The method further includes closing a bore that passes through the main body along an elongate axis of the main body. The method further includes deflecting an intervention assembly along a guide surface of the main body into the lateral section. The method further includes controlling the intervention assembly to perform the intervention operation within the lateral section.

Abstract: A multilateral well access system includes a directional guide and a mating surface profile. The directional guide includes a main body and an outer surface profile disposed on the main body. The main body defines a guide surface oriented non-parallelly to an elongate axis of the main body and a bore passing through the main body along the elongate axis. The mating surface profile is formed complementary to the outer surface profile of the directional guide and is engaged with the outer surface profile to secure the directional guide in a fixed position.

Abstract: A computer system generates a virtual three-dimensional (3D) model of a hydrocarbon reservoir using a machine learning algorithm. The machine learning algorithm is trained using information obtained from multiple hydrocarbon wells. The virtual 3D model includes a reservoir pressure model of the hydrocarbon reservoir indicating variations in reservoir pressure in accordance with time. A fluid saturation model of the hydrocarbon reservoir indicates variations in reservoir saturation in accordance with time. The computer system executes the machine learning algorithm to determine the variations in the reservoir pressure and the variations in the reservoir saturation with respect to the multiple hydrocarbon wells based on the virtual 3D model. A display device of the computer system generates a graphical representation of the variations in the reservoir pressure and the variations in the reservoir saturation in accordance with time.
