Abstract:
Gravity surveys of subterranean formations may be based on the simultaneous measurement of gravity and its derivatives to produce a higher resolution formation map or wellbore log. For example, a method of performing a gravity survey may include positioning a matter wave interferometer relative to a subterranean formation; producing at least one cloud of atoms in the matter wave interferometer; producing a superposition of atoms in two different, spatially separated superimposed clouds from each of the at least one cloud of atoms; propagating the two different, spatially separated superimposed clouds along the matter wave interferometer as they with a gravitational field of the subterranean formation; combining the two different, spatially separated superimposed clouds with a Raman laser beam; measuring an interference produced by producing and combining the two different, spatially separated superimposed clouds; and calculating gravity for the gravitational field of the subterranean formation based on the interference.
