Double pay day for Addax



By Upstream staff 

Addax Petroleum has hit oil and gas with the Ofrima-2 and Udele-2 wells, drilled in OML 137, off Nigeria.

The Ofrima-2 exploration well, drilled on the Ofrima North structure, hit a 140 feet gross oil bearing interval at a depth of about

7000 feet subsea. out

Based on static pressure data measurements, Addax said the well holds light oil of approximately 39 degrees API, similar to the crude oil produced from the Okwori and Nda fields in nearby OML126.

The well also hit three gas-bearing intervals with individual gross gas columns of 29, 43 and 158 feet at shallower and deeper depths relative to the oil-bearing interval.

Ofrima-2 was spudded on 6 April and suspended on 31 May.

Udele-2 was drilled on the Udele West structure immediately following the suspension of the Ofrima North discovery well.

The well hit seven gas bearing intervals with individual gross gas columns of between 41 and 113 feet, 542 feet in aggregate, at depths ranging from 2700 to 5900 feet subsea.

Udele-2 was suspended on 2 July.

Both wells were drilled using Saipem's semi-submersible drilling rig Scarabeo 3 in water depths of about 75 metres at Ofrima North and 170 metres at Udele West.

The Scarabeo 3 is currently carrying out a well workover on the Okwori field and thereafter will go offsite for about three months for routine inspection before returning to OML126 and OML137.

Addax said it plans to re-enter both Ofrima-2 and Udele-2 to carry out flow tests over selected intervals when the Scarabeo 3 returns.

OML137 lies about 50 kilometres from the planned Brass liquefied natural gas terminal.
