HRT Participacoes em Petroleo SA, Rio de Janeiro, said its 1-HRT-1-AM well in Brazil’s Solimoes basin is being logged after penetrating five crude oil intervals in aeolian sandstones in the Devonian Marimari Group and three gas intervals, two in the Jurua formation and one in the Marimari Group.
The 1-HRT-2-AM is at 2,829 m enroute to zones of interest expected at 3,060-3,500 m.
The 1-HRT-3-AM well tested geological structures adjoining the structure already drilled by the 1-GAV-01-AM well, which detected gas in the Jurua formation. Intermediate casing is being set. Gas was detected while drilling in three geological intervals and evidence of liquid hydrocarbons was found in the deeper intervals. Crude oil was detected in the drilling mud during logging.
HRT is setting 7-in. liner. The company decided not to run formation tests at 1-HRT-3-AM at this time. This well and the hydrocarbon accumulations in the 1-CI-1-AM, 1-MR-1-AM, and 1-IP-1-AM wells on the SOL-T-168 block will be part of a future assessment plan.
After setting liner, the rig will move to the 1-HRT-1-192 well in Block SOL-T-192 about 65 km southwest of 1-HRT-3-AM. The 1-HRT-4-AM well is at 1,675 m enroute to zones of interest expected at 2,360-2,700 m.
