Patent number: 9422811Abstract: A tool is to be used within a wellbore including a wall and extending into a formation with formation fluid. The tool includes a packer expandable against the wellbore wall with ports included within the packer to enable formation fluid to flow into the tool from the formation. The ports are arranged in a first port configuration optimized based upon a first predetermined formation property.Type: GrantFiled: December 20, 2013Date of Patent: August 23, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Sylvain Bedouet, Adriaan Gisolf, Cosan Ayan, Peter Hegeman, Ryan Sangjun Lee

Patent number: 7966273Abstract: Apparatus and methods to perform downhole fluid analysis using an artificial neural network are disclosed. A disclosed example method involves obtaining a first formation fluid property value of a formation fluid sample from a downhole fluid analysis process. The first formation fluid property value is provided to an artificial neural network, and a second formation fluid property value of the formation fluid sample is generated by means of the artificial neural network.Type: GrantFiled: April 7, 2008Date of Patent: June 21, 2011Assignee: Schlumberger Technology CorporationInventors: Peter Hegeman, Chengli Dong, Charles Woodburn, Graham Birkett, Nikos Varotsis, Vassilis Gaganis

Patent number: 7277796Abstract: A technique is described for interpretation of IPTT tests. In one implementation, the technique may be configured or designed to standardize the complete interpretation procedure of IPTT in a heterogeneous reservoir, using if available, modern wireline logs (such as, for example, nuclear magnetic resonance and imaging), dynamic data from wireline formation testers and/or any other relevant information (such as, for example, geological description, core data and local knowledge) as constraints on the interpretation. Additionally, an iterative method may be used to define formation layering. An advanced regression technology may also be used to obtain optimized horizontal and vertical permeabilities of reservoir layers.Type: GrantFiled: May 11, 2005Date of Patent: October 2, 2007Assignee: Schlumberger Technology CorporationInventors: Fikri Kuchuk, Chenggang Xian, Jichao Chen, Andrew Carnegie, Peter Hegeman, Mustafa Onur
