Abstract: A method is described for determining well integrity including deploying seismic sensors in a wellbore; attaching a vibrational source to well hardware; using the vibrational source to generate seismic signal that moves through the wellbore; creating a seismic dataset by recording the seismic signal at the seismic sensors; and processing the seismic dataset to make a processed seismic image. The processed seismic image may be displayed on a graphical display in order to identify well integrity problems such as wellbore deformation, well casing damage, or problems with cement.

Abstract: A sleeve for protecting a lockdown screw of a wellhead assembly can include a body having an inner surface and an outer surface, wherein the body has a concave curvature, where the body is configured to be disposed within an upper portion of a recess of a component of the wellhead assembly inside of which the lockdown screw is disposed, where the concave curvature of the body is configured to match that of an inner wall of the component, and where the outer surface is configured to isolate the lockdown screw from an environment in a cavity partially formed by the inner surface when the body is disposed in the upper portion of the recess.

Abstract: A method is described for monitoring a stimulated reservoir volume (SRV) including receiving simulation parameters, performing 3D fully coupled quasi-static poro-elastic finite difference modeling using the simulation parameters, wherein the 3D fully coupled quasi-static poro-elastic finite difference modeling is based on a rescaling of solid rock and fluid flow density parameters and generates simulated temporal quasi-static stresses, and pore pressure. In addition, simulated stresses may be used for performing calculation of the 3D rotation of the simulated stresses to principal directions; performing calculation of the temporal 3D Mohr-Coulomb (MC) failure criteria from the calculated principal stresses and the simulated pore pressure for all or selected time steps; and displaying the computed temporal MC failure criteria results on a graphical display. The method may also be used in time-lapse monitoring of the reservoir for microseismic depletion delineation.

Abstract: A method of deploying an expandable composition in a cement top job in a well system includes identifying evidence of actual or potential gas migration within an annulus cement of the well system. Once the evidence of gas migration is identified, a first component and a second component are mixed in a mixer to form the expandable composition and the expandable composition is pumped from the mixer through a conduit to a top of cement of the annulus cement. The expandable composition expands to form an expanded composition that seals the annulus above the top of cement of the annulus cement. Cement can be added onto the expanded composition.

Abstract: The present invention relates generally to processes for adding a chemical composition to a produced water mixture upstream of a pad related to a well to be fracked. The added chemical composition comprises a drag reducing agent, or a biocide, or a scale inhibitor, or any combination thereof. The produced water mixture comprising the added chemical composition may then be transferred in a pipeline to the well to be fracked. This offers a number of advantages that may include, for example, reducing the footprint at the pad, improved efficacy of biocide, reduced time to transfer produced water, and/or reduced pumping time during the fracking.
