Latest Patents

One of his latest patents is titled "Controlling Fracture Growth." This invention provides methods for controlling the growth of vertically oriented fractures in a subterranean formation during a fracturing treatment. The process involves introducing a first fluid with a known density and a diverting agent into the formation to create a fracture. Subsequently, a second fluid, which may contain proppant and has a different density, is introduced to selectively override or underride the first fluid. This fluid control mechanism effectively directs the first fluid to the bottom or top of the fracture, allowing the diverting agent to screen out and impede further growth of the fracture. The introduction of the second fluid can then be continued to extend the fracture as desired.

Another significant patent by Harris is the "Method for Fracturing Subterranean Formations." This invention outlines a method for forming an easily pumpable gelled fluid capable of yielding an apparent viscosity exceeding 100 centipoise at a shear rate of 40 sec^-1 for over six hours at temperatures above 250°F. The initial gel is created by combining a selected basic aluminum compound and a phosphoric acid ester with a hydrocarbon liquid. After aging this mixture to form the initial gel, an additional quantity of a basic aluminum compound is mixed in. The crosslinked gel is then introduced into a subterranean formation at a sufficient rate and pressure to fracture the formation.
