MEO to sidetrack Heron-2 probe



By Upstream staff 

Melbourne-based MEO Australia said it would sidetrack its Heron-2 well in the Timor Sea after it became blocked above the secondary Plover Sands target.

MEO said testing of the well, which was spudded in October on Permit NT/P68 by the Seadrill jack-up rig West Atlas, had started on 3 January. It confirmed that gas had flowed only from a 15-metre section of the overlying Erlang sands.

It said the Plover section appeared to have been blocked by debris when circulation was lost during drilling of the initial six-inch bore.

MEO said the joint venture drilling the well had agreed to sidetrack the well into the Plover formation to increase the likelihood of striking commercial quantities of gas. It said four-and-a-half-inch liner would be run to allow the Plover and Erlang formations to be production tested.

Following the test, the bore will be plugged back to allow the primary Epenarra structure in the Darwin formation to be tested, the company said.

MEO operates the Heron well and permit with a total 90% interest through its TSP Arafura Petroleum and Oz-Exoil units, while Petrofac holds a 10% stake.
