Abstract
A method for predicting hydrocarbon recovery in a subterranean formation may include generating pre-heating data associated with fracturing in a sample from the subterranean formation, heating the sample with RF power to cause additional fracturing in the sample, and generating post-heating data associated with additional fracturing in the sample after heating with RF power. The method may also include detecting change between the pre-heating data and post-heating data, and predicting hydrocarbon recovery from the subterranean formation based upon the detected change.
Claims23
A method for predicting hydrocarbon recovery in a subterranean formation comprising:
- generating pre-heating data associated with fracturing in a sample from the subterranean formation;
- heating the sample with radio frequency (RF) power to cause additional fracturing in the sample;
- generating post-heating data associated with additional fracturing in the sample after heating with RF power;
- detecting change between the pre-heating data and post-heating data;
- and
- predicting hydrocarbon recovery from the subterranean formation based upon the detected change.
A method for hydrocarbon recovery in a subterranean formation comprising:
- generating pre-heating data associated with fracturing in a sample from the subterranean formation;
- heating the sample with radio frequency (RF) power to cause additional fracturing in the sample;
- generating post-heating data associated with additional fracturing in the sample after heating with RF power;
- detecting change between the pre-heating data and post-heating data;
- predicting hydrocarbon recovery from the subterranean formation based upon the detected change;
- applying RF power to the subterranean formation based upon the predicted hydrocarbon recovery;
- and
- recovering hydrocarbons from the subterranean formation after applying RF power thereto.
