Abstract
A method for using markers with a drilling plan uses a first log file of a first well in order to identify and store one or more markers that have a name, a true vertical depth (TVD) and a waveform. Second well log data generated while a second well is being drilled is monitored in real time. The second well log data is compared to the one or more markers to located a match to at least one marker in a predetermined TVD range. An estimated TVD value and an uncertainty range value are assigned to each of the at least one planned marker. When a matching marker is located for one of the one or more markers in the predetermined TVD range a report is generated.
Claims30
A method for using markers with a drilling plan, comprising:
- using, by a computer system, a first log file of a first well in order to identify and store one or more markers that have a name, a true vertical depth (TVD) and a waveform;
- monitoring in real time, by the computer system, second well log data generated while a second well is being drilled;
- comparing the second well log data to the one or more markers to locate a match to at least one marker in a predetermined TVD range;
- creating, by the computer system, at least one planned marker for the second well corresponding to a located match within the one or more markers in the predetermined TVD range;
- assigning, by the computer system, an estimated TVD value and an uncertainty range value to each of the at least one planned marker;
- and
- reporting when a matching marker is located for one of the one or more markers in the predetermined TVD range.

A system, comprising:
- a network interface;
- a processor coupled to the network interface;
- a memory coupled to the processor and configured to store a plurality of instructions executable by the processor, the instructions including instructions for:
- using, by a computer system, a first log file of a first well in order to identify and store one or more markers that have a name, a true vertical depth (TVD) and a waveform;
- monitoring in real time, by the computer system, second well log data generated while a second well is being drilled;
- comparing the second well log data to the one or more markers to locate a match to at least one marker in a predetermined TVD range;
- creating, by the computer system, at least one planned marker for the second well corresponding to a located match within the one or more markers in the predetermined TVD range;
- assigning, by the computer system, an estimated TVD value and an uncertainty range value to each of the at least one planned marker;
- and
- reporting when a matching marker is located for one of the one or more markers in the predetermined TVD range.

A method for using one or more planned markers with a drilling plan, comprising:
- using, by a computer system, a first log file of a first well in order to identify and store one or more markers that have a name, a true vertical depth (TVD) and a waveform;
- monitoring in real time, by the computer system, second well log data generated while a second well is being drilled;
- comparing the second well log data to the one or more markers to locate a match to at least one marker in a predetermined TVD range;
- creating, by the computer system, at least one planned marker for the second well corresponding to a located match within the one or more markers in the predetermined TVD range;
- assigning, by the computer system, an estimated TVD value and an uncertainty range value to each of the at least one planned marker;
- generating an indication that the identified plan marker matches the corresponding identified and stored marker in the predetermined TVD range as the determination is completed;
- and
- forwarding the indication for corrective action to the drilling plan responsive to the indication.
