The 15th bidding round on March 29 raised more than 8 billion reais (US$2.42 billion) in signature bonuses.

The Brazilian government could launch a mega-auction in June, but it needs to resolve issues regarding valuation of reserves first.

Argentina, which is still defining the areas to be included in its auction, expected to receive bids in late November and is giving incentives for oil companies currently exploring at its large Vaca Muerta shale play to move from pilot to full development phase.

A subsidiary of the New York-based E&P reached an agreement with an ExxonMobil affiliate to acquire a 15% participating interest in offshore Guyana's Kaieteur Block.

The bids had been scheduled to be received April 5. The change, announced by the National Hydrocarbons Agency (ANH) late on April 4, marks the fifth time the auction for the 15 crude and gas areas in the country’s northwest has been rescheduled.

ExxonMobil along with Petrobras and Qatar Petroleum shelled out 2.8 billion reais (US$844 million) for a block in Brazil’s offshore Campos Basin.

Oil Secretary Marcio Felix said the government would seek to undo the decision, without providing details. But he said success was unlikely before the round on March 29, which will grant companies concessions to explore and produce in the areas.

Reservoir Evaluation

GeoPark Ltd. (NYSE: GPRK) has confirmed the successful drilling and testing of the Tigana Norte 4 appraisal well in the Tigana oil field in Llanos 34 Block in Colombia.

GeoPark Ltd.’s Tigana Norte 3 appraisal well has confirmed the Tigana/Jacana oil field’s extension toward the northeastern limits of Colombia’s Llanos 34 Block.

Anadarko, the operator, said the well hit 79 m to 110 m (260 ft to 360 ft) net of natural gas pay.

A test conducted with an electric submersible pump in the Guadalupe Formation across multiple sand units resulted in a production rate of about 1,800 barrels of oil per day (bbl/d) of 16 degrees API, with a 17% water cut through a choke of 38/64 mm and wellhead pressure of 80 pounds per square inch, the company said.

GeoPark said the well was drilled 780 m north of the Jacana 3 appraisal well further down dip to a bottom-hole location below the previous lowest-known oil, where it hit oil in the Guadalupe Formation.

ExxonMobil encountered about 20 m (65 ft) of high-quality, oil-bearing sandstone reservoir. The well was safely drilled to 5,597 m (18,363 ft) depth in 2,067 m (6,781 ft) of water. Drilling commenced Jan. 29.
