Abstract:
A method and apparatus or treating a subterranean well formation to stimulate the production of hydrocarbons utilizing foam diversion in the well formation.
Abstract:
An electrochemical battery cell with an oxygen reduction electrode and having improved electrolyte leakage resistance. The cell includes a component, disposed between the oxygen reduction electrode and an air inlet in the cell housing, through or around which air can pass. Upon contact with electrolyte, the component is transformed to form an electrolyte seal.
Abstract:
The current invention provides improved methods and compositions for completing a well bore. In one aspect, the current invention provides a process for preparing a foamed well composition. The process utilizes air to foam the composition after the air has been treated to lower the oxygen content below that concentration necessary to support combustion. Additionally, the current invention provides a process for completing and/or treating a well bore using a foamed composition wherein the foam is generated with reduced oxygen content air. Finally, a preferred embodiment of the invention provides a foamed cement composition wherein the gaseous portion of the composition is air having a reduced oxygen content.
Abstract:
A method of fracturing a subterranean formation comprising the steps of: providing a coarse-foamed fracturing fluid comprising a liquid fracturing fluid component, a gas, proppant particulates, and a foaming agent; and placing the coarse-foamed fracturing fluid into a portion of a subterranean formation at a pressure sufficient to create or extend at least one fracture therein.
