Abstract: A method for determining a hydrocarbon-bearing reservoir quality prior to a hydraulic fracture treatment based on completions index is disclosed. The method comprises a step performing a test determining a hydraulic pressure at which a hydrocarbon-bearing reservoir will begin to fracture by pumping a fluid in a wellbore, wherein the wellbore extends from a surface to the reservoir and the wellbore has one or more perforations in communication with reservoir; a step generating a pressure transient in the wellbore, the pressure transient travels from the surface to the reservoir through the perforations and reflects back the surface after contacting the reservoir; a step measuring response of the pressure transient at sufficiently high sampling frequency; a step determining fracture hydraulic parameters of the perforations and the reservoir using the measured response; and optimizing a stimulation treatment to the reservoir based on the determined fracture hydraulic parameters.

Abstract: A species transfer device in communication with at least two streams, one stream having a higher potential of a species than a lower potential stream. The species transfer device is capable of removing a portion of the species from the high potential stream, and transferring the removed species into the low potential stream. The species transfer device incorporates a housing assembly, exchange matrix and optionally, a sorbent. The housing assembly contains both the exchange matrix and optionally a sorbent inside a housing enclosure and between a sealing enclosure, and provides for the entrance and exhaust of the first and second streams therethrough. The exchange matrix can be, but need not be, in the form of a wheel having an average linear coefficient of thermal expansion at 25 to 800° C. of less than about 20×10−7/° C. The housing assembly with the housing and sealing enclosures enables the species transfer device to run efficiently through a range of pressures.
