Assignee:

Schlumberger Technology Corporation - Sugar Land TX

International Classification:

G01V 140

US Classification:

702 6, 33304

Abstract:

A borehole survey method is provided for processing continuous measurements of the earths magnetic and gravitational fields obtained while drilling a borehole. The present invention improves borehole acquisition of targeted geological structures by substantially reducing continuous measurement errors attributable to noise, shock and vibrations from turning the drill bit against rock.

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.

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.

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 47/12
G01V 3/34

US Classification:

3408533, 3408537, 3408546

Abstract:

A system and method for communicating with a downhole tool is disclosed. In one embodiment, a telemetry system for communicating with a downhole tool in a wellbore includes a first electrode. A modulated electric current flows from the first electrode through a formation to the downhole tool. The telemetry system also includes a downlink box, which provides the modulated electric current to the first electrode. The downhole tool comprises a sensor unit, which detects the modulated electric current. The telemetry system includes a second electrode that allows the modulated electric current to return to the downlink box. The telemetry system also includes an uplink telemetry, wherein the uplink telemetry does not comprise electromagnetic telemetry. In some embodiments, the downlink may be operated while mud pumps are turned off. The downlink may also be operated while the downhole tool is sending uplink telemetry by a method other than electromagnetic current.

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.

US Classification:

3408532, 3408531, 3408535

Abstract:

Methods for drilling a new well in a field having a plurality of existing cased wells using magnetic ranging while drilling are provided. In accordance with one embodiment, a method of drilling a new well in a field having an existing cased well includes drilling the new well using a bottom hole assembly (BHA) having a drill collar having by an insulated gap, generating a current on the BHA while drilling the new well, such that some of the current passes through a surrounding formation and travels along a casing of the existing cased well, measuring from the BHA a magnetic field caused by the current traveling along the casing of the existing cased well, and adjusting a trajectory of the BHA to avoid a collision between the new well and the existing cased well based on measurements of the magnetic field.
