Tap Oil completes drilling at Manora field in Gulf of Thailand

Tap Oil has announced the completion of the drilling programme at the Manora Oil field, located in the Gulf of Thailand.

Tap Oil has completed a drilling programme at the Manora Oil field, located in the Gulf of Thailand.

The drilling programme saw the first well spud on 9 July. Batch drilling of the top-hole sections of three wells was first taken up, following which drilling of the reservoir sections was carried out.

For the programme, the Ensco 115 jack-up drilling rig was used. The two horizontal developments wells, MNA-24H and MNA-23H, were drilled from the Manora platform. These wells targeted undeveloped reserves in the 300 series sands. The MNA-24H horizontal development well was drilled to a final measured depth of 2,216m, while the MNA-23H was drilled to 2,216.1m depth.

With the completion of drilling at the two wells, they have been handed over for production operations. Before long-term production commences, multi-rate testing will be carried out at the wells.

Providing an update on the MNA-22H well, the company stated that the aim of this well is to offer a second drainage point in the 490-60 and 500 reservoirs that were completed in the nearby MNA-20H well.

On 4 August, the MNA-22H well was drilled to a final measured depth of 2,133m. A petrophysical interpretation of well logs indicates that at the MNA-22H well had an oil net pay of 56.5 m in total in the 490-60 and 500 sands.

Currently, the work in the MNA-22H well has been suspended. At a later date, the well will be completed with a work over rig.

As the development programme completed within budget and before the deadline, the rig was demobilised on 14 August. Ensco 115 jack-up rig will be used again for further exploration drilling in November 2019.

The Manora oil field is located in the G1/48 concession of the Gulf of Thailand. It lies in 44m of water approximately 80km from the coast of Thailand.

Mubadala Petroleum is the operator of the field and has a 60% interest in the offshore property. Tap Energy holds a 30% interest in the field, while Northern Gulf Petroleum holds the remaining 10% interest.
