Arc spuds new Dongara well

“Dongara-32 is designed as a follow-up to the successful Dongara-31 well to test the production potential of the Arranoo Sandstone reservoir of the Dongara Field,” said Arc managing director Eric Streitberg.

“The Arranoo reservoir lies above the Dongara Sandstone reservoir and has produced both gas and oil and the Dongara 31 well tested at approximately 7 million cubic feet per day of gas.”

The vertical depth to the prognosed top of the primary objective Arranoo Sandstone is 1400m, (1608m measured depth). The proposed total depth of the well is 1,800m measured depth, including two 160m laterals. The well is expected to take 18 days to drill and complete.

“The Dongara-32 well has been designed incorporating the results of Dongara-31 and will again test the production potential of this reservoir using a combination of high angle well bores and laterals,” Streitberg said.

“The surface location of the well is adjacent to the Dongara-24 and Dongara-31 wells. Because of the drilling rig’s proximity to Dongara-31 it is not possible to bring that well into production until Dongara-32 is completed. The objective is to then bring both the Dongara-31 and Dongara-32 wells into production as soon as the rig is released from Dongara-32.”

Dongara-32 is 100%-owned by ARC Energy.
