Preexisting faults in a near-critical failure condition may be activated by hydraulic fracturing. Quite often these faults are not detected by reflection seismic data. The results of such reactivation can be breaching water formation, well bore shear, and induced seismicity.
Real-time microseismic monitoring can detect the activation of these pre-existing faults notifying the engineer of this dangerous activity and allow for an intervention in the pumping program to reduce the continuing slip on these faults.
Frac Hits / Parent – Child Wells
In the last few years, there has been an increase in the drilling of infill wells, also known as child wells. The aim of these infill wells is to produce hydrocarbons left in place from older(parent) wells, or to continue field development with increasingly modern completion designs. The common experience shared throughout the industry is that the interaction between parent and child wells has often proven to decrease EUR and capital efficiency for both the parent and child wells.
FracRx® analysis in a post-mission mode will model the interference between wells and allow for a better well spacing and frac design on future projects in the same field. Real-time FracRx analysis can allow for an intervention in a pumping program as soon as interference between the wells is detected.
