US Patent:

6736221, May 18, 2004

Filed:

Dec 21, 2001

Appl. No.:

10/028864

Inventors:

Christopher R. Chia - Houston TX
Wayne J. Phillips - Houston TX
Darren Lee Aklestad - Sugar Land TX

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 4700

US Classification:

175 45, 33303

Abstract:

A method is disclosed which utilizes multiple overlapping surveys to estimate a position in a wellbore and related position uncertainty. Multiple surveys are often taken over the same portion of a wellbore either concurrently or sequentially and/or using various instruments. Each survey generates an estimated survey position and related uncertainty for a given location in the wellbore. By combining the estimated survey positions and uncertainties for these overlapping surveys, a resultant position and related ellipsoid of uncertainty is estimated. This resultant position estimates a position in the wellbore by incorporating the estimated survey positions and uncertainties of multiple overlapping surveys.

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 47/00
E21B 47/02

US Classification:

1662542, 175 40, 175 45, 175 50

Abstract:

A method for surveying a wellbore may include deploying a deployable wellbore survey tool into the wellbore, collecting survey data as the deployable survey tool traverses the wellbore, and determining wellbore position information based on the survey data. In one example the method may include landing the deployable wellbore survey tool on a component of a bottom hole assembly.

Appl. No.:

12/169382

Inventors:

Wayne J. Phillips - Houston TX, US

Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

E21B 47/00

US Classification:

175 24, 175 45

Abstract:

A method includes obtaining a first set of survey data at a first point along a wellbore, estimating a present wellbore position based on at least the first set of survey data, determining a related ellipse of uncertainty at the present wellbore position, comparing the related ellipse of uncertainty of the present wellbore position to a threshold, and selecting a methodology for a subsequent survey based on a comparison of the related ellipse of uncertainty to the threshold.

International Classification:

E21B 47/022

US Classification:

702 6, 702 7, 702 9, 702 10, 702 11, 7315201, 7315202, 1662414, 1662551, 175 24, 175 45

Abstract:

Various methods are disclosed, comprising obtaining a plurality of raw depth measurements for a wellbore; obtaining survey data about a bottom hole assembly; obtaining depth compensation information; calculating a plurality of compensated depth measurements from the raw depth measurements and the depth compensation information and one or more additional corrections for residual pipe compliance, tide, and rig heave; calculating sag angle and correcting the survey data with the sag angle; determining a high fidelity wellbore trajectory from the compensated depth measurements and the survey data; and then employing the high fidelity wellbore trajectory in various drilling, formation evaluation, and production and reservoir analysis applications. Depth compensation information may comprise at least one of weight on bit, a friction factor, temperature profile, borehole profile, drill string mechanical properties, hookload, and drilling fluid property. The surveys may include both static and continuous surveys.

Appl. No.:

5/875165

Inventors:

Wayne A. Phillips - Houston TX

International Classification:

F02D 900
F02D 1702

US Classification:

123198F

Abstract:

A system is provided for varying the number of active cylinders in a multi-cylinder internal combustion engine, in response to the operating requirements of the engine. When the engine reaches that part of its operating range where the torque requirement is such that operation of all of the cylinders is not required to provide adequate and efficient power, certain cylinders are rendered inactive, thereby reducing the fuel consumed by the engine. A control system is provided which, upon sensing a reduced torque requirement upon the engine, activates a switch which de-energizes the spark generating electrodes of certain cylinders, and concurrently activates solenoid valve means whereby fuel vapor in the deactivated cylinders may be bypassed through the cylinders and returned to the fuel supply system of the engine for later use. In one embodiment of the system, novel spark producing means is provided which includes the fuel bypass valve means. The spark producing means is so constructed that it may be substituted for a conventional spark plug of an internal combustion engine thereby providing for simple and economical installation of the fuel conservation system upon existing internal combustion engines.

International Classification:

E21B 44/00
G05B 15/02
E21B 7/06

Abstract:

A drilling tool in accordance to one or more aspects includes a processor to determine a demand attitude and an instantaneous drilling tool attitude, evaluate a control law to derive a control law tool face, and to convert the control law tool face to an equivalent tool face, and a steering device to apply the equivalent tool face to control a drill attitude of the drilling tool.
