... Abstract In the Alaskan North Slope field of Nikaitchuq, the standard shut-down strategy of oil producers was to inject warm diesel inside the tubing of the wells for freeze prevention of the tubing. The procedure requires that a Gas Lift Valve (Shear Orifice Valve) located at 2,000 ft...

... effects can also be included. For all samples, the procedure will enable determination of when leakage paths appear (as a function of applied thermal cycles and time), where they appear (in the bulk cement or at its interfaces) and what their sizes, geometries and distributions are. This opens...

Abstract A numerical modeling procedure was developed, using the finite-elementsimulator ABAQUS/Standard, to predict the local buckling and post-bucklingresponse of high strength pipelines subject to combined state of loading. Thenumerical procedures were validated using test data from large...
