Currently at a depth of 738 metres, Nuevo Malolos-1 will enter its main objective zones after the 9 5/8” casing is set, Gas2Grid managing director Gundi Royle said.
“The plan is to core and drill stem test the two primary objectives in the Maingit Formation (M2.1 sand) at 2,691 ft and the Toledo Formation (T5.3 sand) at 6,086 ft once encouraging gas shows have been noted,” Royle said.
“There are a number of other sand members in the Maingit and Toledo formations which will also be investigated and tested should there be sufficient hydrocarbon shows.”
Gas2Grid, which holds a 100% interest in the 100,000 hectare licence, announced in August it was appraising the Malolos feature to establish a sustainable gas flow.
SC44 contains two 1960s gas discoveries, Malolos-1 and Zaragosa-1. In 1960 Malolos-1 flowed gas from drill stem tests at rates of 5 million cubic feet per day and 12.6 million cubic feet per day from zones at 850m and 1850m respectively.
The company re-entered this well on December 10.
The Malolos feature, with potential gas resources of 50 bcf, is on trend with three other culminations - Butak, Barili and Esperanza - which have estimated gas resources of 240 bcf, based on assumptions from the Malolos-1 well, according to Gas2Grid.
