Patent number: 9796047Abstract: Systems and methods are provided for laser heating in a fluid environment (30). Such a system may include a laser generator (12) and a laser output sub (16) separate from one another via an optical fiber (18). The laser generator may generate a heating laser pulse over the optical fiber. The laser output sub may emit the heating laser pulse to heat a substrate (22) in the fluid environment (30). To enable the heating laser pulse to pass between the laser output sub (16) and the substrate (22), the laser output sub may dispense a laser-transmissive optical grease or a laser-transmissive magnetic fluid, or may generate a vacuum cavitation bubble in the fluid between the laser output sub (16) and the substrate (22).Type: GrantFiled: February 25, 2014Date of Patent: October 24, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Richard Saenger

Patent number: 8907268Abstract: The present disclosure provides systems and methods where an electron focusing device can be combined with a scintillation detector to better focus the electrons generated by a light sensing device. The scintillation detector can include a scintillation crystal that is covered by an inner light-reflecting coating layer where the scintillation crystal may emit photons due to measurement radiation(s). The light sensing device can include a photomultiplier that may receive the photons emitted by the scintillation crystal and convert them into the electrons generated. The electron focusing device can include a metal ring magnet or one or more conducting coils encircling the scintillation crystal that may create a magnetic field so as to focus the electrons generated by the light sensing device.Type: GrantFiled: January 10, 2011Date of Patent: December 9, 2014Assignee: Schlumberger Technology CorporationInventor: Richard Saenger
