Abstract
Embodiments of the present disclosure include a method that includes activating a neutron generation unit operable to emit neutrons toward a target for a first period of time. The method also includes recording first measurement data, via a detection unit, during the first period of time. The method further includes deactivating the neutron generation unit after the first period of time. The method also includes processing at least a portion of the first measurement data after the first period of time, the first measurement data being correlated to burst gate. The method includes recording second measurement data, via the neutron detection unit, during a second period of time, the second measurement data being correlated to a capture gate.
Claims17
A method, comprising:
- activating a neutron generation unit operable to emit neutrons toward a target for a first period of time;
- receiving first measurement data, via a detection unit, during the first period of time;
- storing the first measurement data;
- deactivating the neutron generation unit after the first period of time;
- processing at least a portion of the stored first measurement data after the first period of time, the first measurement data being correlated to a burst gate;
- receiving second measurement data, via the neutron detection unit, during a second period of time, the second measurement data being correlated to a capture gate;
- and
- processing the second measurement data during the second time period, wherein at least a portion of the first measurement data is processed in parallel with the second measurement data.
A computing device, comprising:
- a microprocessor;
- and
- memory including instructions that, when executed by the microprocessor, cause the computing device to:
- obtain first measurement data from a detection unit, the first measurement data recorded during a burst gate of a neutron generation unit;
- obtain second measurement data from the detection unit, the second measurement data recorded during a capture gate of the neutron generation unit, the capture gate starting after a waiting period from an end of the burst gate;
- process at least a portion of the first measurement data during the waiting period;
- process at least a portion of the second measurement data during the capture gate;
- and
- process at least a portion of the first measurement data during the capture gate in parallel with the second measurement data.
A system for conducting measurement operations, the system comprising:
- a neutron measurement device forming at least a portion of a downhole tool string, the neutron measurement device operable to generate measurement data for detecting a wellbore characteristic, wherein the neutron measurement device comprises:
- a neutron generator operable to emit neutrons toward a target;
- a plurality of detectors fixed relative to the neutron generator and operable to detect gamma rays from the target;
- a microprocessor;
- and
- memory including instructions that, when executed by the microprocessor, cause the system to:
- activate the neutron generator for a first period of time;
- store first measurement data during the first period of time;
- deactivate the neutron generator after the first period of time;
- disregard second measurement data during a second period of time, the second period of time being after the first period of time;
- record third measurement data during a third period of time, the third period of time being after the second period of time;
- process at least a portion of the first measurement data during the second period of time and the third period of time;
- and
- process at least a portion of the third measurement data during the third period of time, wherein at least a portion of the first measurement data is processed in parallel with at least a portion of the third measurement data.
