Hihi-1 & 1A Well Completion Report

Hihi-1 was spudded on October 29th 2004 and was completed on November 13th 2004. Hihi-1A was sidetracked from Hihi-1 on November 13th 2004 with drilling continuing until completion on November 23th 2004. Hihi-1 was drilled to a depth of 1936m AHKB (-1685m TVDSS) and Hihi-1A was drilled to 1797m AHKB (-1395m TVDSS). Elevated gas of up to 4% total and oil shows were recorded in both Hihi-1 and 1A but commercial hydrocarbons were not encountered. Hihi-1 and 1A were plugged and abandoned on November 23rd 2004. ; The wells were part of a four well programme to test amplitude anomalies in the Miocene Urenui and Manganui Formations interpreted using the newly acquired Kaimata 3D seismic survey. The primary target was the basin floor fan systems of the Mt Messenger Formation with a secondary objective of Moki Formation sands. Hihi-1 is a vertical well whilst Hihi-1A is a sidetrack to the northeast to test an adjacent anomaly updip of the Hihi-1 H1 1619 sand which had slightly elevated gas and weak oil shows.
