Publication number: 20170351001Abstract: Example computer-implemented methods, computer-readable media, and computer systems are described for accurate localization of wireless sensor devices in underground oil reservoirs. In some aspects, every sensor measures respective received magnetic field strengths (RMFSs) on a plurality of respective magnetic induction (MI) links and transmits the measured respective RMFSs to at least one anchor devices. A set of distances is determined from the measured respective RMFSs. The set of distances is processed through an ordered sequence of algorithms, namely weighted maximum likelihood estimation (WMLE), semi-definite programming (SDP) relaxation, alternating direction augmented Lagrangian method (ADM), and conjugate gradient algorithm (CGA), to generate accurate localization of the wireless sensor devices in underground oil reservoirs.Type: ApplicationFiled: August 24, 2017Publication date: December 7, 2017Applicants: Saudi Arabian Oil Company, Truva CorporationInventors: Howard K.

Patent number: 9810057Abstract: Systems for determining a size, extent, and orientation of a hydraulic fracture of a reservoir, are provided. An exemplary system can include a plurality of RFID transponders modified to include an acoustic transmitter, and an RFID reader modified to include both an RF transmitter and a pair of acoustic receivers, to be deployed in a wellbore adjacent a hydraulic fracture. In embodiments, the acoustic transmitter includes a thermo-acoustic device. The system includes program product configured to receive acoustic return signal data to determine the three-dimensional location of each RFID transponder within the reservoir, to map the location of each RFID transponder, and to responsively determine the size, extent, and orientation can be determined.Type: GrantFiled: May 29, 2015Date of Patent: November 7, 2017Assignee: Saudi Arabian Oil CompanyInventors: Howard Khan Schmidt, Abdullah Awadh Al-Shehri

Methods of employing and using a hybrid transponder system for long-range sensing and 3D localizaton
Patent number: 9187993Abstract: Methods of employing and using a hybrid transponder system to determine the size, extent, and orientation of a hydraulic fracture of a reservoir, are provided. An exemplary method can include the steps of inserting a plurality of transponders into a fluid, injecting the fluid carrying the transponders through casing perforations and at least one fracture aperture in a wellbore and into a hydraulic fracture, actuating each of the transponders by a reader to provide an acoustic return signal to the reader, determining a three-dimensional position of each of the transponders, mapping the location of the each of the transponders, and determining characteristics of the hydraulic fracture responsive to the three-dimensional position of each of the plurality of transponders. The method can be implemented utilizing a reader including an RF transmitter and one or more acoustic receivers along with typically a substantial plurality of transponders each containing an RF receiver and an acoustic transmitter.Type: GrantFiled: April 26, 2011Date of Patent: November 17, 2015Assignee: Saudi Arabian Oil CompanyInventors: Howard Khan Schmidt, Abdullah Awadh Al-Shehri -
