Patent number: 8886467Abstract: The chemical distance between fingerprints of fluid samples from a reservoir can be determined using statistical analyses. Upon performing chromatographic analyses on fluid samples from the reservoir, certain peak height values from the chromatograms are selected, and various peak height ratios are formed using the selected peak height values. An experimental distribution of the differences between the peak height ratios is produced using two chromatograms from one of the fluid samples and a theoretical distribution of the differences of the peak height ratios are produced assuming the two chromatograms are from the one of the fluid samples. An uncertainty model of the peak height values is optimized and the parameters of the optimized uncertainty model are used to modify the theoretical distribution. The interquartile ranges of the experimental distribution and the modified theoretical distribution are determined and the chemical distance between the samples is determined using the interquartile ranges.Type: GrantFiled: May 17, 2010Date of Patent: November 11, 2014Assignee: Schlumberger Technology CorporationInventor: Xavier Nouvelle

Apparatus for determining the concentration of a conductive fluid present in a fluid filled borehole
Patent number: 8849572Abstract: An apparatus for determining the concentration of a conductive fluid present in a fluid filled bore hole is described. Such apparatus are known as water hold-up meters and are frequently used in oil, gas and water filled bore holes. In bore hole applications, data bandwidth between a down hole device and the surface can be limited, while determining water hold-up based on down hole measurements can be data intensive. A technique is proposed for calculating the water hold up that requires less data to be transmitted between the down hole device and the surface.Type: GrantFiled: June 6, 2008Date of Patent: September 30, 2014Assignee: Sondex Wireline LimitedInventors: Guy Harvey Mason, James Andrew Gulliver, Derek George Hayes, Paul Franklin Steel, Kenneth Tomkins, Andrew John Stevens -

Patent number: 8793072Abstract: The invention is a method of monitoring an underground formation into which a gas is injected or from which a gas is produced, by a stratigraphic inversion of seismic data with anamorphosis of impedances. Pre-injection and post-injection seismic data are acquired. A pre-injection seismic impedance cube IP1 is determined by a stratigraphic inversion of the pre-injection seismic data. An anamorphosis function ? is defined by a function comprising a positive lower limit B1, an upper limit B4, an identity interval defined between limits B2 and B3, with B1<B2<B3<B4. A value for each limit B1, B2, B3 and B4 is associated with each cell of the cube. Post-injection seismic impedances IP2 are determined by a stratigraphic inversion of the post-injection seismic data wherein the anamorphosis function ? is applied to seismic impedances IP2. The gas is located within the zone by identifying the cells where IP2<IP1.Type: GrantFiled: March 9, 2011Date of Patent: July 29, 2014Assignee: IFP Energies NouvellesInventors: Michel Leger, Vincent Clochard
