Abstract
In one embodiment the application pertains to a logging-while-drilling tool comprising an inner bore with a distal end and a proximal end. The inner bore of the LWD tool comprises: at least one sensor to measure a property of the formation around a wellbore; a power unit; and a short-hop transmitter configured to communicate with a short-hop receiver of an MWD system. A processor in the inner bore is configured to acquire, process, and store formation data. The processor is operably connected to the short-hop transmitter such that at least a portion of the formation data can be communicated to the short-hop receiver of an MWD system.
Claims14
A logging-while-drilling tool comprising:
- an inner bore with a distal end and a proximal end wherein the inner bore comprises:
- at least one sensor to measure a property of the formation around a wellbore;
- a power unit;
- a short-hop transmitter configured to communicate with a short-hop receiver of an MWD system;
- and
- an electronics subsystem comprising a processor configured to acquire, process, and store formation data wherein the processor is operably connected to the short-hop transmitter such that at least a portion of the formation data can be communicated to the short-hop receiver of an MWD system.
A system comprising:
- a logging-while-drilling tool comprising:
- an inner bore with a distal end and a proximal end wherein the inner bore comprises:
- at least one sensor to measure a property of the formation around a wellbore wherein the sensor comprises at least one receiving antenna and at least one receiving antenna;
- a power unit;
- a short-hop transmitter configured to communicate with a short-hop receiver of an MWD system;
- and
- an electronics subsystem comprising a processor configured to acquire, process, and store formation data wherein the processor is operably connected to the short-hop transmitter such that at least a portion of the formation data can be communicated to the short-hop receiver of an MWD system;
- and
- an MWD system which is separate from and lacks a wired connection to the logging-while-drilling tool wherein the MWD system comprises a short hop receiver configured to wirelessly receive and decode transmitted data from the a short-hop transmitter of the logging-while-drilling tool.
