| 20080272931 | Method and Apparatus for Measuring a Parameter within the Well with a Plug - The invention provides a system for measuring a parameter within a well comprising: a first apparatus comprising a first reel of first wound optic fiber line (or fiber) able to be unwound from the first reel, at least a first sensor able to measure the parameter of the well, wherein information on said parameter can be transmitted trough the first optic fiber; a second apparatus comprising a second reel of second wound optic fiber line able to be unwound from the second reel, an extremity of the second optic fiber being fixed to a reference point; a light transmitter or receiver device linked to the reference point and able to generate or detect a light pulse through the second optic fiber line; and means to exchange said light pulse between first and second optic fiber line. | 11-06-2008 |
| 20090020335 | METHODS, SYSTEMS AND APPARATUS FOR PRODUCTION OF HYDROCARBONS FROM A SUBTERRANEAN FORMATION - Methods, systems, and apparatus that are suitable for use in production of hydrocarbons from subterranean heavy oil deposits employ a subterranean cavity in communication with a borehole. The cavity is preferably formed along a U-tube borehole by coiled tubing reaming operations and/or radial drilling and explosive blasting | 01-22-2009 |
| 20090038854 | SYSTEM AND METHOD FOR DRILLING WELLBORES - A system and method are provided for drilling a wellbore. The wellbore is formed with a drilling tool that cuts through a formation. A pumping system removes cuttings from the drilling tool and also transports the cuttings along at least a portion of the wellbore formed behind the drilling tool. | 02-12-2009 |
| 20090071722 | WELLBORE CONSOLIDATING TOOL FOR ROTARY DRILLING APPLICATIONS - A subpart of a drill string is described having an outer circumferential surface which is contoured and adapted to engage the wall of the borehole with a small angle of attack while exerting during rotary drilling operations an compacting pressure on mud cake and/or cuttings present in the annulus between the drill string and the borehole. | 03-19-2009 |
| 20090087912 | TAGGED PARTICLES FOR DOWNHOLE APPLICATION - A tagged object includes a main body and a plurality of coded particles. Each coded particle may have a miniature body and be configured to provide a resolvable optical emission pattern when illuminate. The plurality of coded particles may be immobilized to the main body. A method for performing oilfield monitoring may include disposing of different types of tagged objects at different locations, wherein the different types of tagged objects each comprise a plurality of coded particles. Each of the coded particles may have a miniature body containing rare earth elements configured to produce a unique optical emission pattern when illuminated. The method may include allowing an event to trigger the release of one of the different types of tagged objects from one of the different locations. In addition, the method may include identifying the released tagged objects by unique optical emission patterns, in some cases in order to determining an occurrence location of the event. | 04-02-2009 |
| 20090321141 | Methods and Apparatus for Wireline Drilling On Coiled Tubing - Apparatus for drilling an underground borehole, comprising:

| 20100044101 | METHODS, SYSTEMS, AND APPARATUS FOR PRODUCTION OF HYDROCARBONS FROM A SUBTERRANEAN FORMATION - Methods, systems, and apparatus that are suitable for use in production of hydrocarbons from subterranean heavy oil deposits employ a subterranean cavity in communication with a borehole. The cavity is preferably formed along a U-tube borehole by coiled tubing reaming operations and/or radial drilling and explosive blasting. | 02-25-2010 |
| 20100108306 | VIBRATION DAMPING SYSTEM FOR DRILLING EQUIPMENT - A downhole tool is described designed to be suspended from a surface location into a wellbore ( | 05-06-2010 |
| 20100319998 | WELLBORE CONSOLIDATING TOOL FOR ROTARY DRILLING APPLICATION - A subpart of a drill string is described having an outer circumferential surface which is contoured and adapted to engage the wall of the borehole with a small angle of attack while exerting during rotary drilling operations an compacting pressure on mud cake and/or cuttings present in the annulus between the drill string and the borehole. | 12-23-2010 |
| 20110120725 | WELLBORE INSTRUMENTS USING MAGNETIC MOTION CONVERTERS - A directional drilling system, a drilling hammer and a fluid flow telemetry modulator use a plurality of magnets arranged to convert rotational motion into reciprocating linear motion. Various types of motor can provide rotational motion to a part of the magnets and various linkages and other devices can cause steering or operation of a modulator valve. A torsional drilling hammer uses a plurality of magnets arranged to convert reciprocating linear motion into reciprocating rotational motion. A motor and linkage drives the linearly moving part of the magnets, and the rotating part provides torsional impact be striking the linearly moving part of the magnets. | 05-26-2011 |
