HRT confims gas potential in Amazon's Solimões basin
RIO DE JANEIRO – HRT O&G has concluded the drill stem test of a cased hole in the Tucumã prospect (1-HRT-192/02-AM), block SOL-T-192, in the Solimões Basin, of the Amazonas state.
The prospect, located approximately 30 km to the south of the Juruá Field, was tested to identify hydrocarbons in a faulted anticlinal structure in a regional SW-NE oriented structural lineament sub parallel to the Juruá and Tefé gas trend.
Two intervals were selected for the drill stem test, achieving the following results:
a) DST – 01: Interval 2,254.0 to 2,260.3 m - Juruá Formation Lower Member – Reached a stable production rate of 18.4 MMcfgd, with a choke of 40/64-in. (The estimated AOF for this test is 56.5 MMcfgd.
b) DST – 02: Interval 2,208.0 to 2,217.0 m - Juruá Formation Lower Member – Reached a production rate of 5 MMcfgd, with a choke of 40/64-in.
“This positive test confirms the existence of a new structural trend in our blocks to the south and southwest of this well” said Milton Franke, CEO of HRT O&G.
The drill stem test results, together with the gas findings in wells 1-HRT-5-AM and 1-HRT-9-AM, confirm the gas trend to the south and the potential for gas in the SOL-T-191 and SOL-T-192 Blocks and open a new exploratory play fairway for SOL-T-214, SOL-T-215 and SOL-T-216 blocks, where the company has identified several exploratory prospects for future new wells to be drilled.
The presence of a richer liquid bearing gas/condensate identified in the DST’s in a relatively underexplored area of the basin, reinforces the geological model interpreted for the area, and consolidates the potential for gas in the region and supports the gas monetization project, according to HRT.
HRT is the operator of 21 blocks in the Solimões basin, which it is exploring in co-operation with TNK-Brasil.
