Canoro preparing for full field development of Amguri

Vol 11, PW 4 (28 Jun 07) Exploration & Production

Canadian explorer Canoro Resources is turning its attention to "full-field development" of its 53-sq km Amguri oilfield in Assam, following disappointing results from two exploration wells in nearby exploration block AA-ON/7.

This week (20th June) onland rig Century 28 from Century Drilling of Australia spud the first of two planned appraisal wells at Amguri, designed to confirm estimated in-placeprospectiveresources of 201m barrels of oil equivalent. The first well, Amguri 10B, will be followed in quick succession by well Amguri 11.

"Hopefully the appraisal programme will turn these resource estimates into reality," Canoro tells us. "When these two wells are drilled we should have a good enough understanding to begin full field development.

The number of potentialdevelopment wells is impossible to say until results come in from the two appraisal wells." To save costs, Canoro plans to use the first 1600 metres of the well bore of original appraisal well Amguri 10 for well Amguri 10B, which will be sidetracked west to a new target location in the producing Barail formation. An earlier appraisal well, Amguri 10A, was sidetracked in a southerly direction.

"The exact location of Amguri well 11 will depend on the results of 10B," adds Canoro. "Results from both these wells willstart tofirm up the true potential of the Amguri field." On 24th May last year Canadian consultant Sproule International issued a recoverable resource best estimate at Amguri of 78m barrels of oil equivalent: 46m barrels of oil; 4m barrels of condensate and 167bn cubic feet of gas.

This estimate wasprepared with the use of old 2D seismic covering the block. Canoro has since acquired fresh 3D from a blanket survey of the 53-sq km field carried out late last year.
