20160115780 | COMPLETIONS INDEX ANALYSIS - 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. | 04-28-2016 |
20150152318 | FRACTURING PROCESS USING LIQUID AMMONIA - A fracturing fluid that includes the combination of liquid ammonia and a proppant, and a method for fracturing an underground formation by pumping this fracturing fluid into a wellbore that extends to the formation. The process includes generating pressure in the wellbore, creating fractures in the formation using the liquid or gelled ammonia and proppant slurry, and releasing pressure from the wellbore. The ammonia released from the liquid or gelled ammonia helps stabilize clays in the formation and the proppant helps to maintain the fractures in the formation. | 06-04-2015 |
