Australia's Gas2Grid revealed in a statement Monday it has decided to terminate drilling operations at 3,450 feet in the Gumamela-1 exploration well. The well, sited in Gas2Grid’s wholly-owned Service Contract 44, onshore Cebu, will soon undergo wireline logging tests.
In its statement, Gas2Grid said that the well was drilled past the top Cebu Limestone – where it intersected a formation that comprised mainly of claystone, siltstone with minor sandstone, with gas shows recorded while drilling the sandstone intervals.
A spokesperson representing Gas2Grid told Rigzone that while there are hydrocarbon shows in the well, the results are likely to be insignificant.
"If a reservoir of gas was hit, and the gas gushes up fast – it implies that a large gas section might be present. This is not the case for Gumamela-1," the spokesperson said.
The drilling rig – Gardner Denver 500 SCR 800 HP – used to drill Gumamela-1 will be moved to the site of Ilang-1, the third well of Gas2Grid's exploration campaign. The rig, which was being employed to drill deep, hot water wells in Taiwan, was transported to Gas2Grid's yard in San Fernando mid-June last year.
Gumamela-1 is sited 3 kilometers (2 miles) of the recently drilled Jacob-1 well, which failed to encounter any hydrocarbon shows. Jacob-1 is the first exploration which Gas2Grid drilled.
