Use of thin liquid spacer volumes to enhance hydraulic fracturing

Abstract: A method for enhanced hydraulic fracturing which comprises injecting a proppant laden fracturing fluid into a formation or reservoir at a rate and pressure sufficient to fracture said formation. Next, a thin spacer fluid is injected into the created fracture. Afterwards, a proppant laden fracturing fluid is injected into the formation at a rate and pressure sufficient to hold the created fracture open which allows proppant to be more evenly distributed throughout the created fracture as proppant falls through the spacer fluid thereby avoiding proppant convection in the created fracture while obtaining substantially improved propping of the fracture.

Membrane composed of a pure molecular sieve

Abstract: A synthetic, non-composited microporous membrane comprises a continuous array of crystalline molecular sieve material. A method is also provided for the preparation of the membrane, and methods are provided for using the membrane as a catalyst, or as a non-catalytic separation membrane for liquid or gaseous mixtures.

Catalytic dewaxing of hydrocarbon oils

Abstract: An improved process for catalytically dewaxing a hydrocarbon oil is disclosed. In this process the waxy oil is contacted in the presence of hydrogen with a dense zeolitic dewaxing catalyst associated with a nickel-tungsten hydrogenation component. The dewaxed oil has unexpectedly good stability and a low bromine number compared with prior-art processed oils. The process may be used to dewax crude oils, fuel oil fractions and lubricating oils.
