Frac design optimisation system



Challenge Summary

Fracking has brought a revolution to the oil and gas industry in the unconventional reservoir by extracting oil and gas that cannot be produced with conventional techniques due to lower permeability of the reservoir rock. The conventional process for design and monitoring of the fracking operation is through a physics-based model, whereby the overall process is being simulated by inputting all the pressure and depth parameters into the pre-built model based on earlier operations. These models have high computational efficiency but are limited in terms of fracture shape and flow conditions. The properties and distribution of formation matrix are pre defined and are static in nature. The conventional models assume fracture length as constant and thus are unable to simulate small quantity fractures. The current requirement is a data driven approach through advanced analytics to strategise right fracturing technique based on the rock properties to reduce unwanted situations like pressure out and screen out.
