    Cliff Head Multi-well drilling Programme

    Cliff Head 3 Appraisal Well: drilling ahead at
    1,017 metres

    Norwest Energy NL advises that as of 6am (Western Standard Time) today the Cliff Head 3 appraisal well was drilling ahead at a depth of 1,017 metres. The bottom hole location is located 91 metres southwest of the surface position. Planned operation is to run 9 5/8 inch casing in the Kockatea Shale prior to drilling into the reservoir.

    Cliff Head 3 is the first of at least 3 exploration and appraisal wells to be drilled by the Ensco 53 jack up during the 1st Quarter 2003 in both WA-286-P and adjacent TP/15. A number of contingent wells are planned depending upon the results of the firm drilling programme. As such the total number of wells to be drilled will be determined as the programme progresses.

    Cliff Head 3 surface location is 2.4 kilometres northwest of the bottom hole location of the Cliff Head 2 appraisal well. Cliff Head 3 will be drilled as a near vertical well to a total depth of 1,311 metres subsea. This well will evaluate the reservoir potential of the upthrown fault block in the northern portion of the Cliff Head Oil Field.

    Subject to the initial drilling results, one to two sidetrack holes may be drilled from the Cliff Head 3 surface location. The first would be designed as a minimal sidetrack to twin the original (Cliff Head 3) hole so as to provide an optimum opportunity to core the main zone/s of interest, run casing and test the potential reservoir. The second potential sidetrack, dependent upon the results of the two earlier holes, would be designed to further appraise the field through the drilling of an additional higher-angled sidetrack hole to a bottom hole location approximately 750 metres to the south of the Cliff Head 3 surface location. Regardless of results all wells in this programme will be plugged and abandoned because it is more economic to drill new production wells and position platforms

    Because the potential reservoir depth is relatively shallow regionally (1,100 metres to 1,900 metres subsea), individual wells are not expected to take more than a week to drill.

    Following drilling and if warranted, testing, of the Cliff Head 3 appraisal well together with any sidetracks, the Ensco 53 Jack up drilling rig is scheduled to drill Twin Lions 1 in the adjacent TP/15 permit. The Twin Lions structure is situated about 5 kilometres to the north-northeast of the Cliff Head Oil Field and is geologically similar, forming part of the same trend.

    If Twin Lions 1 is successful, it is likely that a second well will be directionally drilled from the number 1 location to test the extent of any hydrocarbons westward into WA-286-P.
