Curtin University petroleum engineering researchers are using a high-speed drilling simulator to replicate the increasingly popular industry method of drilling deep boreholes in tight gas formations and shales.
Curtin University’s Department of Petroleum Engineering Professor Vamegh Rasouli said the research was being undertaken with the aim of improving efficiency in hard rock drilling, but could be extended for shale gas drilling and fracturing.
Professor Rasouli said the simulator was capable of performing normal, over-balanced and under-balanced drilling, as well as simulating the use of different mud types and drilling through hard rock using diamond-impregnated bits.
“Simulation of drilling practices in the laboratory will be very beneficial for field operations, as we can study the effects of different parameters on drilling efficiency,” Professor Rasouli said.
“There are various issues to overcome during the drilling and production phases of gas wells, including wellbore instability during drilling and hydraulic fracturing for enhanced recovery.”
