Abstract: A system for optimizing a tubular running operation (TRO) in which a running string is disposed in a wellbore includes sensors located at the wellsite, plus one or more processors, displays, and user-input devices, which may be at the wellsite or elsewhere. The sensors are configured to measure running string parameters including the running strings position within the well, the running and rotation rates, and loads acting at the top of the running string. Based on this information, the processor(s) perform torque-and-drag analysis (TDA) in the top-down direction to estimate downhole loads on user-selected running string components, accounting for measurement and modelling uncertainties. Based on the estimated loads, the processor(s) calculate one or more damage indicators, which are communicated to the user via the display(s), enabling the user to take corrective action to prevent or manage damage to the running string.

Abstract: A system for optimizing a tubular running operation (TRO) in which a running string is disposed in a wellbore includes sensors located at the wellsite, plus one or more processors, displays, and user-input devices, which may be at the wellsite or elsewhere. The sensors are configured to measure miming string parameters including the running strings position within the well, the miming and rotation rates, and loads acting at the top of the miming string. Based on this information, the processor(s) perform torque-and-drag analysis (TDA) in the top-down direction to estimate downhole loads on user-selected miming string components, accounting for measurement and modelling uncertainties. Based on the estimated loads, the processor(s) calculate one or more damage indicators, which are communicated to the user via the display(s), enabling the user to take corrective action to prevent or manage damage to the running string.

Abstract: A method for distributing injection fluid in a horizontal well bore in fluid communication with hydrocarbon bearing formation begins by determining flow resistance characteristics of the formation along at least a portion of the length of the horizontal well bore. An injection tubing string having a sidewall defining a tubing bore is injected into the horizontal well bore. The tubing string is provided with ports having a selected distribution and geometry. The annulus geometry is selectively controlled along the length of the tubing string through at least one of axial distribution of eccentricity and flow area of the annulus, so as to provide selected flow restriction characteristics along the annulus, such that when injection fluid is pumped into the tubing, a resulting flow resistance network is formed by the tubing bore, the ports, the annulus and the formation, resulting in a desired distribution of the fluid into the formation.

Abstract: A Moineau stator includes a tube (10) having lobes (3) arranged in a configuration which is adapted to interact with a rotor and formed through a hydroforming process.
