Filed:

Dec 8, 2006

Appl. No.:

11/608469

Inventors:

Pabitra N. Sen - Ridgefield CT, US
John P. Horkowitz - Sugar Land TX, US

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

G01V 3/00

US Classification:

324303, 324306

Abstract:

A system and method for measuring fluid flow in a wellbore in an earth formation using time-of-flight (TOF) sensing and remote detection nuclear magnetic resonance (NMR) techniques, by applying a magnetic field to the formation to polarize spins present in a portion of the formation, providing an encoding shell in the formation, selecting an encoding volume from the encoding shell, applying an encoding signal to excite the spins in the encoding volume, introducing a time delay to the encoding signal, providing a detection shell in the formation, applying a detection signal to the detection shell, detecting an NMR signal generated by the migration of spins from the encoding shell to the detection shell, and collecting TOF data corresponding to time elapsed from when a spin is encoded to when the spin reaches the detection shell.

International Classification:

G01V 1/40

US Classification:

702 7, 702 6, 702 11, 702 16

Abstract:

A method for processing well logging data includes method dividing the well logging data into a number of constant dimensional effect segments, where each constant dimensional effect segment defines an interval having a similar dimensional effect on the log response. The well logging data is taken from a highly deviated well. The method further includes dividing the constant dimensional effect segments into a number of constant property intervals, each constant dimensional effect segment including at least one corresponding constant property interval, and each constant property interval defining a wellbore distance over which a formation property is substantially constant that results in a log response having a low variance. The method further includes providing the constant property intervals to an output device. The method further includes determining constant property intervals in 3D volume space projected them into true stratigraphic thickness, and providing the resulting log-squared data to the output device.

International Classification:

G01V 1/40
G01V 3/08

US Classification:

702 7, 702 11

Abstract:

A technique provides a methodology for improving surveys of subterranean regions. The methodology comprises estimating macro anisotropy and an intrinsic or micro anisotropy of an overburden. A surface electromagnetic survey is conducted, and the data from the survey is inverted based on or including information gained from estimating the macro anisotropy and/or intrinsic anisotropy. A processor system can be used to conduct the inversion with the adjustments for anisotropy to improve the information provided by the survey.

International Classification:

G06F 19/00

US Classification:

702 11

Abstract:

A logging tool capable of making different types of measurements is provided, and a plurality of measurements on a formation are obtained. Certain mineral properties of the formation are assumed and a mixed properties theorem for the formation is invoked. Upper and lower velocity limits for sonic waves traveling through the formation are determined using the above information. Biot's constant is also computed using the above information. LWD data on the formation is obtained and an effective stress is determined. A total stress is determined and, from that and the other information, a pore pressure is determined.

Abstract:

Compositions of lost circulation materials are provided that are useful for identifying the location of fluid loss in a wellbore. The compositions include additives which enhance a property of the composition such that they can be detected by an LWD or MWD tool capable of measuring the property when the composition is deployed in a region of loss, and can be distinguished by the LWD or MWD tool from the formation and mud fluid. Methods are also provided for using the composition to detect the location of fluid loss and for controlling the loss of fluid from the wellbore. The methods involve deploying the compositions in loss regions by adding the compositions to drilling mud, and measuring a property of the compositions using an LWD or MWD tool.
