Abstract: The disclosure presents processes to locate one or more quantum gravimeters at a hydrocarbon well site, with at least one quantum gravimeter at a surface location. Zero or more additional gravimeters, whether quantum gravimeters or non-quantum gravimeters, can be located downhole a wellbore of the well site. Gravitational data collected from various gravimeters can be analyzed to produce analyzed gravitational parameters and subterranean formation parameters. In some aspects, the gravitational data can be processed, such as by an inversion algorithm or a noise reduction algorithm. The generated results can be used to calibrate non-quantum gravimeters located proximate the well site or downhole the wellbore, identify a depth and direction of a water front, identify the fluid flow of hydrocarbons or water in the subterranean formation, to identify orphaned hydrocarbon reservoirs, or other characteristics of fluid flow or subterranean formation parameters, such as subterranean formation damage.

Abstract: Apparatuses and methods for setting posts of columns in to the ground are provided. Expandable metals in response to hydrolysis that tend to fill in spaces and cavities, even over time, which is a useful feature when setting columns into the ground. A hydrolyzing fluid can be supplied, as necessary, to cause the hydrolysis of the expanding metal, or supplied by ground water. Upon hydrolysis, the expanding metal expands around the column to adhere and grip the column securely, while the metal may also expand outwardly to increase cross-sectional bulk lending to a more overall stabilization of a set column. The expandable metal may be provided as a solid sleeve drivable into the ground with a post, as an auger that can be used to turn a column into the ground or, as a rod that can be driven through the interior of a column into the ground.
