Longtom-3 Intersects 'Substantial' Gas Column
Nexus Energy reported that, as of August 9, 2006, the Longtom-3 ST1 well had reached a measured depth of 2,563 meters. The well is located in the VIC/P54 permit, in the offshore Gippsland Basin, Victoria.
--Longtom 3 well ST1 (side track 1) has intersected a substantial gas column over 4 separate reservoir intervals --The intersections in the pilot hole and the sidetrack well confirm Nexus' geological model for the field --Nexus will now commence the planned horizontal section of the well which is expected to lead to completion and production testing.
Operations conducted since last Report:
Following the successful drilling of the Longtom-3 PH (pilot hole) the well was plugged back to the casing shoe at 995 meters and the side track well, Longtom-3 ST1 drilled. This side track has been drilled as a deviated well and will also be plugged back to 2,380 meters before the horizontal well is drilled laterally through the Longtom gas sands and tested as planned.
To date 1,568 meters of new hole has been drilled in Longtom-3 ST1, and at the present depth of 2,563 meters, the bottom hole location is 1,050 meters from the Longtom-3 PH bottom hole location, and 800 meters from Longtom-2 bottom hole location.
Summary of Results:
In Longtom-3 ST 1 98 meters of gross gas sand (vertical thickness) has been intersected in four reservoir units over a 414 meters interval within the Admiral Formation.
The side track well was drilled to intersect the reservoir sands in a crestal position in order to provide additional data on sand quality and lateral continuity. Based on wire line log and pressure data, the individual sands, including the sands which were cored but not successfully tested in Longtom-2, are interpreted to be laterally continuous between all Longtom wells, while being vertically isolated from each other.
Planned future well operations are to run casing across the upper gas reservoirs in Longtom-3 ST 1 and to drill the well horizontally through the lower gas sands. The horizontal section of the well will provide further information in relation to the quality and lateral continuity of the lower Admiral reservoirs. After the drilling of the horizontal section it is intended that the well will be completed with both the upper and lower sands being tested to confirm the productivity of the key gas zones. Upon completion of a successful production test the well will be suspended as a future producer.
Nexus' Managing Director Mr Ian Tchacos said, "The results of the well to date are very encouraging. The Admiral reservoir intersections in the pilot hole and in the side track well have provided sufficient confidence in our geological interpretation to proceed with the horizontal section of the well as originally planned.
"We have been able to take advantage of advanced seismic processing techniques (seismic amplitudes) to determine the quality and distribution of the thicker gas filled sands in the section. This has positive implications for optimizing the horizontal part of this well and the placement of future wells. I am particularly pleased about our ability to properly evaluate both well bores with down hole logs and formation pressure measurement tools. This additional information is key to refining our understanding of the Longtom field's resource potential."
