Publication number: 20240069239Abstract: Methods and systems are provided that perform sonic measurements in a high-angle wellbore or horizontal wellbore or vertical wellbore penetrating highly dipped formation layers where the formation layers can have a high degree of dip relative to the wellbore. Sonic data can be generated from the sonic measurements and processed using multiple arrival event processing to determine formation porosity, elastic rock properties and geometric information for a tool layer and nearby shoulder bed. Such information can be integrated into a 2D or 3D layered model of the formation. The elastic rock properties of the tool layer and shoulder bed derived from the multiple arrival event processing can provide more representative elastic property values, which can account for heterogeneity along the wellbore.Type: ApplicationFiled: August 30, 2023Publication date: February 29, 2024Inventors: Nicholas N. Bennett, John Adam Donald, Olusegun M. Akinyose, Shouxiang Mark Ma, Sherif Ghadiry, Wael Abdallah

Patent number: 11604301Abstract: A method is provided for identifying and characterizing structures of interest in a formation traversed by a wellbore, which involves obtaining waveform data associated with received acoustic signals as a function of measured depth in the wellbore. A set of arrival events and corresponding time picks is identified by automatic and/or manual methods that analyze the waveform data. A ray tracing inversion is carried out for each arrival event (and corresponding time pick) over a number of possible raypath types to determine i) two-dimensional reflector positions corresponding to the arrival event for the number of possible raypath types and ii) predicted inclination angles of the reflected wavefield for the number of possible raypath types.Type: GrantFiled: October 24, 2018Date of Patent: March 14, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Nicholas N. Bennett, Reetam Biswas

Patent number: 9846256Abstract: An interactive display of results obtained from the inversion of logging data is produced by obtaining and inverting the logging data using a Monte-Carlo inversion. An interactive plot having a percentile scale plotted against a location parameter is produced and a particular percentile is selected using the interactive plot. A cross-section plot for the particular percentile using the results of the Monte-Carlo inversion is produced. The particular percentile can be a curve representing a best-fit solution or a polyline representing selected solutions. Background color/shading can be displayed on the interactive plot to indicate user-defined constraints have been applied. Uncertain features can be plotted on a corresponding cross-section display using fading. Clusters of solutions that are substantially equally likely, given the measurements at a particular drill location, can be identified and plotted.Type: GrantFiled: August 9, 2011Date of Patent: December 19, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Denis Heliot, Nicholas N. Bennett, Georgi Kutiev, Emmanuel Legandre, Roger Griffiths, Jean-Michel Denichou, Jean Seydoux, Qiming Li, Koji Ito

Patent number: 9703003Abstract: Apparatus and methods of analyzing a composition of a hydrocarbon-containing fluid including using a nuclear magnetic resonance (NMR) tool to conduct a NMR relaxation measurement, a diffusion measurement, or both on the hydrocarbon-containing fluid to obtain NMR data, using a non-NMR tool to conduct an additional measurement of a reference fluid to obtain non-NMR data wherein the additional measurement comprises gas chromatography, optical observation, or both, and using the NMR data and the non-NMR data in an inversion process to determine an indication of the composition of the hydrocarbon-containing fluid. In some embodiments, the indication is determined over 4 chain length nodes.Type: GrantFiled: December 17, 2013Date of Patent: July 11, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Nicholas N.

Patent number: 9582353Abstract: A method of obtaining nuclear magnetic resonance (NMR) data from a subterranean formation may include operating a tool in a subterranean formation for generating both NMR data and NMR scaled data based upon NMR measurements of the subterranean formation. The method also includes operating the tool for encoding and transmitting both the NMR data and NMR scaled data, and receiving and decoding, above the subterranean formation, both the NMR data and NMR scaled data from the tool. The method also includes performing error-correction of the received and decoded NMR data based upon the received and decoded NMR scaled data.Type: GrantFiled: January 30, 2013Date of Patent: February 28, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Nicholas N. Bennett, Lalitha Venkataramanan, Nicholas Heaton

Patent number: 9529109Abstract: Methods and apparatus for determining slowness of wavefronts. An example apparatus includes one or more sources spaced from a receiver. The one or more sources are to transmit one or more signals and the receiver is to receive at least a portion of the one or more signals. The apparatus includes a processor to process waveform data associated with the one or more signals by stacking waveforms of the waveform data based on to linear moveout and sinusoidal moveout.Type: GrantFiled: July 4, 2012Date of Patent: December 27, 2016Assignee: Schlumberger Technology CorporationInventors: Nicholas N. Bennett, Richard T Coates, Jakob Brandt Utne Haldorsen, Douglas E. Miller

Patent number: 6829570Abstract: An oilfield data analysis system is based on a four-tier software model which includes a “shared earth model” and a federation of “directory services”. The first tier is a universal graphical user interface (GUI) which can operate on any inexpensive computer as well as on an expensive workstation, i.e. a “web browser”. The second tier is an application server which is coupled to users via the worldwide web and serves geoscientific software applications. The third tier is a geometric modelling system where geometric data is stored and processed. The third tier embodies the “shared earth model”. The fourth tier is a database management system where non-geometric data is stored. According to the invention, there can be (and preferably are) multiple instances of each tier. Communication of data between different tiers is accomplished via XML data exchange.Type: GrantFiled: November 14, 2000Date of Patent: December 7, 2004Assignee: Schlumberger Technology CorporationInventors: Raj Kumar Michael Thambynayagam, Peter G.
