Abstract

A method for generating a depth-indexed data structure for a reaming operation includes receiving, by a software process, i) well logging data that includes time-indexed data and depth measurement data for an oil well drilling rig, ii) a selection identifying a depth range for a reaming operation by the drilling rig, and iii) values for a certain parameter indicating an operating mode for the drilling rig. Then the software process extracts, responsive to the selected depth range and one of the values of the parameter, a section from the well logging data within the selected depth range, and generates from the section the depth-indexed data structure for the reaming operation.

Claims

1. A method for generating depth-indexed data corresponding to well logging data collected during at least one reaming operation, the method comprising:

receiving, by a software process,

i) the well logging data for a drilling rig including time-indexed data collected during the at least one reaming operation,

ii) a selection identifying a depth range for the at least one reaming operation by the drilling rig, and

iii) values for a parameter, the values indicating respective operating modes for the drilling rig, the values being modifiable after the well logging data collection;

extracting, by the software process responsive to the selected depth range and one of the values of the parameter, a section from the well logging data within the selected depth range; and

generating from the section the depth-indexed data corresponding to the data collected during the at least one reaming operation.

2. The method of claim 1, wherein the parameter is user-selected or program selected.

3. The method of claim 1, wherein the parameter is included in the received well logging data.

4. The method of claim 1, wherein the parameter is included in the received well logging data but changeable responsive to a user-selection.

5. The method of claim 1, comprising:

re-generating the reaming operation data by the process responsive to a user-selected modification of a value of the parameter.

6. The method of claim 1, wherein a first value of the parameter is modified by a user or a program after the well logging data has been acquired.

7. The method of claim 6, wherein the first value is indicative of a simulated operating mode of the drilling rig.

8. The method of claim 1, wherein the value of the parameter is modified after the well logging data has been received by the software process.

9. The method of claim 1, wherein the well logging data is acquired in a real-time mode.

10. The method of claim 1, wherein the well logging data is acquired in a recorded mode.

11. The method of claim 10, wherein the well logging data acquired in the recorded mode includes the values of the parameter selected during a real-time mode.

12. The method of claim 1, wherein the well logging data is received by the software process from well logging sensors while the sensors are in the well.

13. The method of claim 1, wherein the well logging data is received by the software process from a memory that accompanied a drilling tool down the well while the well was being drilled, the data from the memory being received by the process after the drilling tool has been removed from the well.

14. The method of claim 1, wherein the well logging data comprises data measuring operations of the drilling rig including surface measurements.

15. A data acquisition and logging system operable to generate depth-indexed data corresponding to well logging data collected during at least one reaming operation, the system comprising:

a processor; and

a memory storing instructions operable with the processor, the instructions being executed for;

receiving, by a software process,

i) the well logging data for a drilling rig including time-indexed data collected during the at least one reaming operation,

ii) a selection identifying a depth range for the at least one reaming operation by the drilling rig, and

iii) values for a parameter, the values indicating respective operating modes for the drilling rig, the values being modifiable after the well logging data collection;

extracting, by the software process responsive to the selected depth range and one of the values of the parameter, a section from the well logging data within the selected depth range; and

generating from the section the depth-indexed data corresponding to the data collected during the at least one reaming operation.

16. The system of claim 15, wherein the parameter is user-selected or program selected.

17. The system of claim 15, wherein the parameter is included in the received well logging data.

18. The system of claim 15, wherein the parameter is included in the received well logging data but changeable responsive to a user-selection.

19. The system of claim 15, comprising:

re-generating the reaming operation data by the process responsive to a user-selected modification of a value of the parameter.

20. The system of claim 15, wherein a first value of the parameter is modified by a user or a program after the well logging data has been acquired.

21. The system of claim 20, wherein the first value is indicative of a simulated operating mode of the drilling rig.
