Publication number: 20190249536Abstract: Methods and systems for determining subterranean fracture closure are disclosed herein. The methods can include electrically energizing a casing of a wellbore that extends from a surface of the earth into a subterranean formation having a fracture that is at least partially filled with an electrically conductive proppant and measuring a first electric field response at the surface or in an adjacent wellbore at a first time interval to provide a first field measurement. The methods can also include measuring a second electric field response at the surface or in the adjacent wellbore at a second time interval to provide a second field measurement and determining an increase in closure pressure on the electrically conductive proppant from a difference between the first and second field measurements.Type: ApplicationFiled: April 22, 2019Publication date: August 15, 2019Inventors: Chad Cannan, Lewis Bartel, Terry Palisch, David Aldridge, Todd Roper, Steve Savoy, Daniel R.

Patent number: 10301536Abstract: Methods for manufacturing electrically-conductive proppant particles are disclosed. The methods can include preparing a slurry containing water, a binder, and a raw material having an alumina content, atomizing the slurry into droplets, and coating seeds containing alumina with the droplets to form a plurality of green pellets. The green pellets can be contacted with an activation solution containing at least one catalytically active material to provide activated green pellets including the at least one catalytically active material. The method can include sintering the activated green pellets to provide a plurality of proppant particles. The plurality of proppant particles can be contacted with a plating solution containing one or more electrically-conductive material to provide electrically-conductive proppant particles.Type: GrantFiled: August 14, 2015Date of Patent: May 28, 2019Assignee: CARBO CERAMICS INC.Inventors: Chad Cannan, Todd Roper, Steve Savoy, Daniel R.

Patent number: 7803322Abstract: The disclosure is directed to a test media reader module including a housing, a membrane, and an optical imager. The housing is configured to receive a test media adapter and has a barrier wall configured to separate the test media adapter from an interior of the housing. The barrier wall includes a window having an interior side and an exterior side. The membrane is transparent to a wavelength useful for imaging test media in the test media adapter. The membrane has a reactive region and overlies at least a portion of the exterior side of the window. The optical imager is located interior to the housing and is configured to image the test media located on the exterior side of the window along an optical path extending through the window and the membrane.Type: GrantFiled: May 12, 2005Date of Patent: September 28, 2010Assignee: Detekt Biomedical, L.L.C.Inventors: Damon Vincent Borich, Steve Savoy, Michael McAleer, Andrew Milder, Daniel Mitchell
