Patent number: 9976402Abstract: A hydraulic fracture diagnostic system for reservoir evaluation of a high angle wellbore includes a coiled tubing string that extends from the surface to a location within a wellbore. The system includes a sensor and a pump connected to the coiled tubing string. A tool having at least two packing elements and a port positioned between the packing elements is connected to the coiled tubing string. The coiled tubing string positions the tool adjacent a fracture. The packing elements isolate the fracture and the port is configured to provide communication with the isolated portion of the wellbore. A diagnostic method includes pumping a volume of fluid from the isolated portion of a wellbore using a coiled tubing string and monitoring the pressure within the coiled tubing string. Pressure within the coiled tubing string may also be monitored after injection of fluid into the isolated wellbore through the coiled tubing string.Type: GrantFiled: September 18, 2014Date of Patent: May 22, 2018Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Juan Carlos Flores, Elton Frost, Jr., Terrence Quinn

Patent number: 9551213Abstract: An apparatus, method and computer-readable medium for estimating a bulk shale volume of an earth formation. In one aspect, measurements are obtained at a plurality of depths in a wellbore penetrating the earth formation and a first distribution is produced of the obtained measurements. A measurement is obtained at a selected depth in the wellbore and a second distribution is produced using the measurement at the selected depth and the measurements obtained at the plurality of depths. A cumulative distribution is produced cumulative of the first distribution and the second distribution. The bulk shale volume is estimated at the selected depth by comparing the cumulative distribution and the second distribution.Type: GrantFiled: April 6, 2010Date of Patent: January 24, 2017Assignee: BAKER HUGHES INCORPORATEDInventor: Elton Frost, Jr.
