Santos Plans to Sidetrack Henry-2 Pilot Well



AWE has provided an operational update for the Henry-2 pilot well. The Company noted that at 0600 hours today, the rig was preparing to run BOP's after having drilled to 657 meters and having set 13 3/8" casing. Progress for the week was 76 meters.

The Henry-2 pilot well is designed to confirm the quality, thickness and structural elevation of the Waarre "A" Sandstone gas reservoir intersected in the Henry-1 discovery well which is located about 3.5km SE of this pilot hole. This well will be drilled to a planned total depth of 2,047 meters.

The Henry-2 DW1 sidetracked development well will follow immediately after this pilot hole. Henry-2 is located in VIC/P 44, approximately 12 kilometers north west of the Casino gas field. Henry-2 is the last well in the current drilling program, and will develop the Henry field discovered by Henry 1 well in July 2005. Prior to the current well, the Pecten East-1 exploration well, Netherby-1 exploration well and Netherby-1 DW1
development well were drilled.

Pecten East-1 was plugged and abandoned having encountered residual gas. Netherby-1 was a successful exploration well which was immediately followed by a successful development well Netherby-1 DW1.

Participants in VIC/P 44 are:

  • AWE 25.0%
  • Santos Limited (operator) 50.0%
  • Mitsui E&P Australia Pty Ltd 25.0%
