| 20080219097 | ACOUSTIC TELEMETRY TRANSCEIVER - One embodiment includes an apparatus that includes a piezoelectric transducer to generate an acoustic signal that is to modulate along a mandrel, wherein the piezoelectric transducer includes at least one piezoelectric element and at least one electrode that is without non-permanent joints. | 09-11-2008 |
| 20090073809 | METHOD AND APPARATUS FOR ACOUSTIC DATA TRANSMISSION IN A SUBTERRANEAN WELL - The disclosure describes a method and apparatus for effectively communicating data along an acoustic transmission path. The method comprises driving an acoustic transmitter to send a data signal along the acoustic transmission path, where the signal is distorted by ambient noise. The distorted signal is input to a spaced apart plurality of sensors so that consequent time-delayed signals provide reinforcement of the basic signal and attenuation of the ambient noise component when combined. | 03-19-2009 |
| 20090101327 | SURFACE INSTRUMENTATION CONFIGURATION FOR DRILLING RIG OPERATION - One embodiment includes an apparatus comprising a surface slip to support drill tubing and having a communications instrument. | 04-23-2009 |
| 20100252250 | Well Screens Constructed Utilizing Pre-Formed Annular Elements - Construction of well screens utilizing pre-formed annular-shaped elements. A well screen includes a filter layer configured to filter fluid flowing through the well screen and a drainage layer which radially supports the filter layer, the drainage layer including multiple individual annular-shaped elements Another well screen includes a drainage layer configured to support the filter layer, with the drainage layer including at least one cavity molded therein. Another well screen includes a base pipe and a layer made up of multiple individual annular-shaped elements stacked coaxially on the base pipe. A cavity is formed in at least one of the elements. | 10-07-2010 |
| 20100309019 | ACOUSTIC TELEMETRY TRANSCEIVER - One embodiment includes an apparatus that includes a piezoelectric transducer to generate an acoustic signal that is to modulate along a mandrel, wherein the piezoelectric transducer includes at least one piezoelectric element and at least one electrode that is without non-permanent joints. | 12-09-2010 |
| 20110073307 | Forming Structures in a Well In-Situ - Structures can be formed downhole by accumulating already existing materials and/or materials introduced into a well to perform a specified function. The formed structures may be used to obstruct fluid flow of production or injection fluids, carry mechanical loads, control electrical or magnetic properties of components, mechanically actuate a component, as well as others. The materials may be induced to form the specified structure, such as by application of a potential downhole. For example, electrical, magnetic, sonic, biological potentials, or a combination thereof may be established downhole to form specified structures in specified locations to perform specified functions. | 03-31-2011 |
| 20110162834 | SURFACE INSTRUMENTATION CONFIGURATION FOR DRILLING RIG OPERATION - One embodiment includes an apparatus comprising a surface slip to support drill tubing and having a communications instrument. | 07-07-2011 |
| 20110168390 | DOWNHOLE ELECTRONICS WITH PRESSURE TRANSFER MEDIUM - Disclosed embodiments include apparatus and methods for transferring a pressure to downhole electronics with a pressure transfer medium. An embodiment of the apparatus includes a body supporting a moveable pressure transfer member, a pressure transfer medium contained by the body and the moveable pressure transfer member, and an electronic component disposed in the pressure transfer medium, wherein the pressure transfer member is moveable to transfer a pressure to the pressure transfer medium and the electronic component. Another embodiment of the apparatus includes a moveable enclosure and a non-conductive material, wherein the non-conductive material isolates an electronic component from a downhole fluid and the moveable enclosure is operable to transfer a hydrostatic pressure to the non-conductive material and the electronic component. An embodiment of a method includes transferring a downhole hydrostatic pressure to an electronic component via a flexible package and a pressure transfer medium. | 07-14-2011 |
