Solimoes wildcat cased to test oil, wet gas shows

By OGJ edtors

HRT Participacoes em Petroleo SA, Rio de Janeiro, notified Brazil’s ANP that its 1-HRT-3-AM wildcat on Solimoes basin Block SOL-T-168 in northwestern Brazil encountered shows of oil and wet gas and has been cased for formation tests.

The well went to a total depth of 2,680 m in crystalline basement about 7.5 km northwest of Carauari municipal district in Amazonas state.

No oil was observed in drill cuttings, HRT said, but gas chromatography-mass spectrometry identified the presence of liquid hydrocarbons in the Carboniferous Jurua formation and Devonian Uere formation. HRT also ran electric logs, wireline formation tests, and nuclear magnetic resonance and obtained sidewall cores.

HRT has 55% interest in 21 blocks in the western Solimoes basin and has mapped 52 prospects (see map, OGJ, Feb. 7, 2011, p. 54).
