Devonian shows more gas in Brazil Parnaiba well

By OGJ editors
HOUSTON, Sept. 2 -- The OGX Maranhao joint venture reported gas indications in two more Devonian intervals at an exploratory well in Brazil’s onshore Parnaiba basin.

The latest shows are 800 m below the previously announced interval, which drillstem tested gas at an unreported rate from a 10-m section at the top of Devonian at 1,654 m. OGX reported a 15-m flare and a wellhead pressure of 1,900 psi during the test (OGJ Online, Aug. 17, 2010).

The 1-OGX-16-MA well on the PN-T-68 block 260 km southwest of Sao Luis intersected fractured shales of the Pimenteiras formation with up to 909 total gas units and a column of 23 m. Just below that interval, sandstone reservoirs of the Itaim formation indicated 370 gas units in a 25-m column.

The well, on the California prospect, is projected to 3,450 m.

OGX Maranhao, an entity formed by OGX SA with 66.6% interest and MPX Energia SA with 33.3%, is the operator and holds a 70% stake in the block. Petra Energia SA holds the remaining 30%.
