The company said gas readings remained elevated in a 12 metre sandy interval. This corresponds to the Toledo sands, which were encountered in Malolos-1.
Once the logs have been analysed, the company will decide whether to test and complete the well.
On January 4, Gas2Grid announced the well had encountered significant gas shows over a 28-metre interval of thin sand and siltstones at a depth of 678 – 707m in the Upper Maingit Formation. It said this also corresponded to gas peaks observed in Malolos-1.
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.
