Abstract
A technique includes receiving a first dataset that is indicative of seismic data acquired in a seismic survey of a field of wells and receiving a second dataset that is indicative of wellbore data acquired in a wellbore survey conducted in at least one of the wells. The technique includes determining a mechanical earth model for the field based at least in part on the seismic data and the wellbore data.
Claims19
A method comprising:
- receiving a first dataset indicative of seismic data acquired by at least one sensor in a seismic survey of a field of wells;
- receiving a second dataset indicative of wellbore data acquired by at least one sensor in a wellbore survey conducted in at least one of the wells, wherein the first and second datasets are stored in at least one memory;
- determining a mechanical earth model for the field using a processor based at least in part on the seismic data and the wellbore data, including using the seismic data and the wellbore data to spatially distribute at least one rock property over a region of the field in the model where wellbore data is sparse or non-existent;
- and
- predicting a stability of at least one of the wellbores based on the mechanical earth model.
A system comprising:
- an interface to receive a first dataset indicative of a first set of rock properties derived from measurements acquired in a seismic survey of a field of wells and a second dataset indicative of a second set of rock properties of the field independently derived from measurements acquired in a wellbore survey conducted in at least one of the wells;
- and
- a processor to determine a mechanical earth model for the field based at least in part on the first dataset and the second dataset, including using the first dataset and the second dataset to spatially distribute at least one rock property over a region of the field in the model where wellbore data is sparse or non-existent, wherein the processor is further adapted to predict a stability of at least one of the wellbores based on the mechanical earth model.
An article comprising a non-transitory computer readable storage medium to store instructions that when executed by a computer cause the computer to:
- receive a first dataset indicative of a first set of rock properties derived from measurements acquired in a seismic survey of a field of wells;
- receive a second dataset indicative of a second set of rock properties of the field independently derived from measurements acquired in a wellbore survey conducted in at least one of the wells;
- process the first dataset and the second dataset to determine a mechanical earth model for the field based at least in part on the first dataset and the second dataset, including using the first dataset and the second dataset to spatially distribute at least one rock property over a region of the field in the model where wellbore data is sparse or non-existent;
- and
- predict a stability of at least one of the wellbores based on the mechanical earth model.
