Patent number: 10162079Abstract: Systems, methods, and devices for determining a neutron-gamma density (NGD) measurement of a subterranean formation that is accurate in both liquid- and gas-filled formations are provided. For example, a downhole tool for obtaining such an NGD measurement may include a neutron generator, a neutron detector, two gamma-ray detectors, and data processing circuitry. The neutron generator may emit neutrons into a formation, causing a fast neutron cloud to form. The neutron detector may detect a count of neutrons representing the extent of the neutron cloud. The gamma-ray detectors may detect counts of inelastic gamma-rays caused by neutrons that inelastically scatter off the formation. Since the extent of the fast neutron cloud may vary depending on whether the formation is liquid- or gas-filled, the data processing circuitry may determine the density of the formation based at least in part on the counts of inelastic gamma-rays normalized to the count of neutrons.Type: GrantFiled: February 2, 2017Date of Patent: December 25, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Avtandil Tkabladze, Michael Lynn Evans, Kenneth Edward Stephenson

Patent number: 10139518Abstract: A method for determining a corrected neutron gamma density of a formation includes emitting neutrons into a formation using a neutron source to generate gamma-rays. Additionally, the method includes detecting a first count rate of gamma-rays and a gamma-ray spectrum using at least a gamma-ray detector of the downhole tool. The method also includes detecting a second count rate of neutrons using a neutron detector. The method includes using a processor to perform a gamma-ray spectroscopy analysis on the formation based on the gamma-ray spectrum and determining a correction based on results of the gamma-ray spectroscopy analysis. The method includes applying the correction to the first count rate or the second count rate and determining a neutron gamma density of the formation based on a first corrected count rate of gamma-rays or a second corrected count rate of neutrons. The method also includes outputting the determined density of the formation.Type: GrantFiled: June 9, 2016Date of Patent: November 27, 2018Assignee: Schlumberger Technology CorporationInventor: Michael Lynn Evans

Publication number: 20170176634Abstract: Methods and devices for determining accurate neutron-gamma density (NGD) measurements of a broad range of formations. The NGD measurements may be obtained by emitting neutrons into a formation such that some of the neutrons inelastically scatter off elements of the formation and generate inelastic gamma rays. Inelastic gamma rays that return to the downhole tool may be detected. Additionally, fast neutron signals may be directly measured with a fast neutron detector. Some characteristics of certain formations are believed to affect the fast neutron transport of the formations. Thus, if a formation has one or more of such characteristics, a correction may be applied to a count rate of inelastic gamma rays from which the neutron-gamma density (NGD) may be determined.Type: ApplicationFiled: December 18, 2015Publication date: June 22, 2017Inventor: Michael Lynn Evans

Publication number: 20080270230Abstract: A system and method including an Internet preordering system accessible online or onsite at a free-standing kiosk located in or near client properties in which customers may create profiles for the requested services and provide such information to the service provider in advance of the customer's arrival for the requested services. When the customer arrives, the customer identifies himself/herself and the preorder is accessed, verified and/or modified. The preorder is then forwarded to the service provider and the delivery of the service is optimally timed to the readiness of the customer. The customer's profile and preorder information are maintained in a database and used for in-house precision marketing campaigns and cross-promotional opportunities. For example, in a restaurant embodiment, a registered customer is given access to menus and may create menu preferences for a participating restaurant.Type: ApplicationFiled: April 27, 2007Publication date: October 30, 2008Inventors: BRADLEY MARSHALL HENDRICKSON, Billie Lynn Evans

Publication number: 20060080217Abstract: A clearing house process for buying and selling short term liquidity, such as Fed Funds, by financial institutions into an open, fair, and efficient market. The process automatically matches all trades at a preset rate and automatically clears and confirms the trade through a secure on line website. Sellers manage their buying partner risk up front by selecting individual partners, regional partners, and/or partners with predetermined risk profiles, as well as by limiting dollar exposure to each partner as a percent of equity. Rates are published on the system each day. The trading financial institution enters its trades by an individual approved by the financial institution. The clearing house process may also comprise a few selected high quality upstream correspondent banks for excess liquidity and a settlement arrangement through the Federal Reserve Bank.Type: ApplicationFiled: June 15, 2005Publication date: April 13, 2006Inventors: Grenville Blackall, Lynn Evans

Patent number: 6275940Abstract: An automated third party verification system and method for verifying a customer's authorization to switch long distance service providers. The system broadly comprises a customer database manager, a third party verification (TPV) interactive voice response (IVR) system, and a TPV management system. The customer database manager contacts the customer and, responsive to the customer's authorization to switch long distance carriers, creates a text file of the customer's responses to a series of questions supporting the authorization. The text file is sent to the TPV IVR system. The TPV IVR system directs a series of scripted questions, corresponding to those already asked by the customer database manager, to the customer and records the responses as voice clips. The TPV management system presents the voice clips and the corresponding text file to a verifier through a voice data verification module.Type: GrantFiled: April 17, 2000Date of Patent: August 14, 2001Assignee: ANitec Verification, Inc.Inventors: Jim G.
