Abstract

A tubular connection made during various oil and/or gas operations such as a tripping operation can be identified based on received data such as hookload and/or block position data. A type of tubular connected can also identified by comparing hookload and/or block position data to a tubular specification database. The identification of the tubular connection and/or type of tubular connected can be used to measure a machine sequence, such as a tripping sequence. The measurement of the machine sequence can be used to optimize an operation such as a tripping or drilling operation.

First claim

What is claimed is:

1. A method of identification comprising:
receiving, by a processor, data from at least one sensor;
identifying, by the processor, a tripping operation, including whether a tripping operation has commenced and a direction of the tripping operation based, at least in part, on the received data;
identifying, by the processor, a tubular connection made during the tripping operation based, at least in part, on the received data; and
identifying, by the processor, a tubular type associated with the tubular connection based, at least in part, on the received data.

2. The method of claim 1 , further comprising measuring a machine sequence based, at least in part, on the identification of the tubular connection.

3. The method of claim 2 , further comprising adjusting the tripping operation based, at least in part, on the measured machine sequence.

4. The method of claim 3 , wherein adjusting the tripping operation comprises adjusting a timing of positioning of one or more tubulars to be tripped in the tripping operation based, at least in part, on the measured machine sequence.

5. The method of claim 1 , wherein the received data comprises at least one of vertical block position data, hookload data, bit data, standpipe data, mud pump data, or top drive data.

6. The method of claim 1 , wherein the received data comprises at least hookload and block position data over a time interval, and wherein the step of identifying, by the processor, the tubular connection is based, at least in part, on received hookload and block position data over a time interval.

7. The method of claim 6 , wherein the step of identifying, by the processor, the tubular connection comprises determining a pair of a local maximum and a local minimum from the hookload and block position data over the time interval.

8. The method of claim 6 , wherein the step of identifying, by the processor, the tubular connection comprises receiving edge connection data over the time interval, wherein the tubular connection identification is based, at least in part, on the edge connection data.

9. The method of claim 6 , wherein the identifying the tubular type associated with the identified tubular connection includes comparing at least a portion of the hookload and block position data to a database, the identifying the tubular type being based on the hookload and block position data.

10. The method of claim 9 , further comprising, after identifying the tubular type, transmitting the identification of the tubular type to the database.

11. An apparatus comprising:
a tripping identifier configured to receive machine tool data and output tripping data based, at least in part, on the machine tool data, the tripping data including whether a tripping operation has commenced and a direction of the tripping operation;
a tubular connection identifier configured to receive the tripping data and output connection cycle data based, at least in part, on the tripping data, the connection cycle data including whether a connection was made; and
a tubular type identifier configured to receive the connection cycle data and output tubular type data based at least in part on the connection cycle data.

12. The apparatus of claim 11 , further comprising a machine sequence measurer configured to receive the connection cycle data and output a machine sequence measurement based at least in part on the connection cycle data.

13. The apparatus of claim 11 , wherein the tubular type identifier is further configured to receive hookload and block position data and output the tubular type data based at least in part on the hookload and block position data, the tubular type data including a type of tubular connected.

14. The apparatus of claim 11 , wherein the tubular type identifier is further configured to receive tubular specification data and to output the tubular type data based, at least in part, on a comparison of the connection cycle data with the tubular specification data.

15. The apparatus of claim 11 , further comprising a machine sequence measurer configured to receive the connection cycle data and the tubular type data, and output a machine sequence measurement based at least in part on the connection cycle data and tubular type data.

16. An apparatus, comprising:
a processor configured to perform steps including:
receiving data from at least one sensor;
identifying a tripping operation, including whether a tripping operation has commenced and a direction of the tripping operation based, at least in part, on the received data;
identifying a tubular connection made during the tripping operation based, at least in part, on the received data; and
identifying a tubular type of the tubular connection based, at least in part, on the received data.

17. The apparatus of claim 16 , wherein the received data includes at least one of vertical block position data, hookload data, bit data, standpipe data, mud pump data, or top drive data.

18. The apparatus of claim 16 , wherein the processor is further configured to perform steps including measuring a machine sequence based, at least in part, on the identification of the tubular connection.

19. The apparatus of claim 16 , wherein the received data includes at least one of hookload or block position data over a time interval, and wherein the step of identifying the tubular connection is based, at least in part, on the at least one of hookload or block position data over the time interval.

20. The apparatus of claim 19 , wherein the processor is further configured to perform steps including identifying the tubular type of the tubular connection by comparing at least a portion of the hookload and block position data to a database.
