Abstract
Systems and methods of the present disclosure includes a mixer configured to mix air and hydrocarbons and a burner configured to receive the mixed air and hydrocarbons and to generate syngas. The system also includes a cooling system configured to receive the syngas and to cool the syngas to form cooled syngas. The system further includes a collector configured to collect carbon from the cooled syngas as soot. Moreover, the system includes a flare stack configured to receive the cooled syngas and to burn off at least part of the cooled syngas.
Claims11
A method, comprising:
- at a first time, before performing a cleanup operation of a wellbore, receiving a plurality of sets of parameters related to the cleanup operation;
- at the first time, simulating at least a portion of the cleanup operation using the plurality of sets of parameters to determine a functional relationship between CO2 emissions and the plurality of sets of parameters during the cleanup operation;
- recording pertinent results from simulating the portion of the cleanup operation;
- storing results comprising the CO2 emissions for the cleanup operation in an a priori table;
- at a second time, while performing the cleanup operation, identifying a set of real-world operating conditions associated with the cleanup operation;
- at the second time, using the set of real-world operating conditions and the functional relationship between the CO2 emissions and the plurality of sets of parameters, interpolating operating CO2 emissions from the a priori table;
- and
- using the operating CO2 emissions to control the cleanup operation.
A system, comprising:
- a processor and memory, the memory including instructions that cause the processor to:
- at a first time before performing a cleanup operation of a wellbore, receive a plurality of sets of parameters related to the cleanup operation;
- at the first time, simulate at least a portion of the cleanup operation using the plurality of sets of parameters to determine a functional relationship between CO2 emissions and the plurality of sets of parameters during the cleanup operation;
- record pertinent results from simulating the portion of the cleanup operation;
- store results comprising the CO2 emissions for the cleanup operation in an a priori table;
- at a second time while performing the cleanup operation, identify a set of real-world operating conditions associated with the cleanup operation;
- at the second time, using the set of real-world operating conditions and the functional relationship between the CO2 emissions and the plurality of sets of parameters, interpolate operating CO2 emissions from the a priori table;
- and
- use the operating CO2 emissions to manage the cleanup operation.
A non-transitory computer-readable storage medium comprising computer-executable instructions executable by a computer processor, the computer-executable instructions comprising instructions to:
- at a first time before performing a cleanup operation of a wellbore, receive a plurality of sets of parameters related to the cleanup operation;
- at the first time, simulate at least a portion of the cleanup operation using the plurality of sets of parameters to determine a functional relationship between CO2 emissions and the plurality of sets of parameters during the cleanup operation, wherein the functional relationship includes fluid behavior as a function of a choke schedule;
- record pertinent results from simulating the portion of the cleanup operation;
- store results comprising the CO2 emissions for the cleanup operation in an a priori table;
- at a second time while performing the cleanup operation, identify a set of real-world operating conditions associated with the cleanup operation;
- at the second time, using the set of real-world operating conditions and the functional relationship between the CO2 emissions and the plurality of sets of parameters, interpolate operating CO2 emissions from the a priori table;
- and
- use the operating CO2 emissions to manage the cleanup operation.
