HRT O&G Exploração e Produção de Petróleo Ltd. and its partner TNK-Brasil concluded the drilling and evaluation of well 4-HRT-7D-AM, Block SOL-T-194, in the Solimões basin in Brazil.

The well is an adjacent wildcat well drilled to test a southwest extension of the gas and condensate accumulation discovered by well 1-HRT-4-AM. The new prospect was mapped based on seismic data, in a higher structural position with respect to the discovery and tested through a directional well, with an angle of around 45°.

The well crossed the producing reservoir in well 1-HRT-4-AM at 1,250 m (4,101 ft) distance and 11 m (36 ft) structurally higher, as expected, but with a smaller thickness of 2 m (7 ft) and without production capacity. This result confirms that the accumulation of the 1-HRT-4-AM does not have continuity to this southwest mapped extension.

The results of these two wells allow the companies to evaluate the extension of the accumulation of gas and condensate in 12 sq km (4 sq miles). The results of this well do not increase or decrease the 1-HRT-4-AM discovery.

With the collected data, the companies will start the studies of the production potential of such reservoirs aiming to evaluate the Discovery to submit an Assessment Plan to ANP at the right time.

Well 4-HRT-7D is being abandoned considering its potential future use.
