The Valaris MS-1 drill rig is expected to begin mobilisation from the Port of Dampier from May 9 2022, Western Gas has announced.
The MS-1 will take four days to travel to the Sasanof Prospect, which is located 200km northwest of Onslow, Western Australia. Once it reaches Sasanof, drilling of the Sasanof-1 exploration well will commence. The well will reach a depth of 2500 metres in 1070 metres of water.
The entire drilling program is expected to take 26 days from the date the rig leaves the Port of Dampier. Preparations for the program are now underway, with drilling equipment being readied.
“With the rig mobilisation date confirmed, the stage is now set for one of the most anticipated exploration wells on the North West Shelf in many years,” Will Barker executive director at Western Gas said.
“Success on the scale of the independent resource estimates would be a game changer for Australia’s largest gas producing basin, adding a vital new and independent gas supply for domestic energy security and export volumes to meet increasing global LNG demand.”
The Sasanof Prospect is an updip that covers an area of 400 square kilometres. It is 20 km west of the Mentorc Gas and Condensate Field, which contains reservoirs of high-quality gas and condensate. Like the Mentorc field, early data indicates that Sasanof could be another giant gas discovery; it is estimated to contain a 2U Prospective Resource of 7.2 Tcf gas and 176 Million bbls condensate (P501), with a high case 3U Prospective Resource estimate of 17.8 Tcf gas and 449 Million bbls condensate (P101).
Sasanof-1 will be Westerns Gas’s first well drilled in its extensive exploration of the Equus Gas Project.
