Abstract: A method and a system for using machine learning technologies to predict the value and timing of operational parameters. These predictions are then used to identify the risk of certain well incidents to occur, and if so notify responsible personnel thereof as to allow preventive actions to be taken.

Abstract: The invention describes a method for creating a digital archive for information generated in drilling and well operations, as well as for planning such operations. The invention further describes a system for linking, storing and accessing the information in a data store, and graphical user interfaces enabling users to accessing information made available in the system. The described system allows internet based (cloud), thus allowing users to access information from different physical and virtual location.

Abstract: Method for controlling the state of an operation in a hydrocarbon exploration and recovery environment, including creating at least one function model, said function model including at least one function, executing at least one function within said function model, defining a plurality of function controls, a pre-determined combination of given function controls within said plurality of function controls defining a signature event, an occurrence of said signature event being indicative of a specific state of said operation, and monitoring the occurrence of said signature event during execution of a certain function included in said at least one function model.

Abstract: An assembly for a production string with a downhole pump is disclosed which makes use of the polished bore in the top of the liner already installed in the wellbore. Lugs on the assembly align themselves with longitudinal grooves in the top of the liner assembly as an antirotation feature for when the downhole pump is operated. A signaling assembly, involving a collet which can be ultimately released, gives the surface personnel the feedback they need to know that the assembly has been set in the proper place in the top of the liner string, as opposed to another location in the wellbore. Seals, preferably stacks of opposed chevron seals, can be used to bridge the gap between the assembly and the seal bore at the top of the liner.
