Assignee:

Curlett Family Limited Partnership - Cody WY

International Classification:

E21B 716

US Classification:

175 65, 175 67, 175424

Abstract:

A method and system for drilling or cutting a subterranean well or formation using a drilling rig a drill string a plurality of solid material impactors a drilling fluid and a drill bit is disclosed. This invention may have particular utility in drilling wells for the petroleum industry and for cutting formation in the mining and tunnel boring industries. In a preferred embodiment, a plurality of solid material impactors are introduced into the drilling fluid and pumped through the drill string and drill bit to impact the formation ahead of the bit. At the point of impact, a substantial portion by weight of the impactors may have sufficient energy to structurally alter, excavate, and/or fracture the impacted formation. The majority by weight of the plurality of solid material impactors may have a mean diameter of at least 0. 100 inches, and may structurally alter the formation to a depth of at least twice the mean diameter of the particles comprising the impacted formation.

Appl. No.:

13/432206

Inventors:

John L. Maida - Houston TX, US
Etienne M. Samson - Cypress TX, US
David P. Sharp - Houston TX, US

Assignee:

Halliburton Energy Services, Inc. - Duncan OK

International Classification:

E21B 47/09
E21B 31/06

US Classification:

1662551, 166 665

Abstract:

Fiber optic enabled casing collar locator systems and methods include a wireline sonde or a coil tubing sonde apparatus configured to be conveyed through a casing string by a fiber optic cable. The sonde includes at least one permanent magnet producing a magnetic field that changes in response to passing a collar in the casing string, a coil that receives at least a portion of the magnetic field and provides an electrical signal in response to the changes in the magnetic field, and a light source that responds to the electrical signal to communicate light along an optical fiber to indicate passing collars.

International Classification:

G01V 3/00

US Classification:

3408547

Abstract:

Disclosed are wireline tool systems including a casing collar locator tool and one or more logging tool(s). The logging tool(s) collects information regarding a formation property or a physical condition downhole, and produces a modulated magnetic field to communicate at least some of the collected information. The casing collar locator tool includes a light source and a sensor. The light source transmits light along an optical fiber in accordance with a sensor signal. The sensor produces the sensor signal in response to magnetic field changes attributable to passing collars in a casing string, and to the modulated magnetic field produced by the logging tool(s). Related telemetry methods are also described.
