Gas2Grid Confirms Absence of Significant Hydrocarbons in Gumamela-1 Well

change text size

Australia-listed Gas2Grid confirmed in a statement Tuesday that its Gumamela-1 exploration well, sited in its wholly-owned Service Contract 44, onshore Cebu, bears no sign of significant hydrocarbons.

The company added that it has decided to plug and abandon Gumamela-1, after having drilled the well to a depth of 3,450 feet to within a dominantly claystone and siltstone with minor sandstone Oligocence age formation immediately below the Cebu Limestone. Gas2Grid is at present preparing to set cement plugs in the well.

The company is meanwhile preparing to complete the workover and testing of the Malolos-1 well, also located onshore Cebu. Oil was recovered on several drillsteam tests conducted in the well – over a gross interval of 7,169 feet to 7,326 feet (2,185 meters to 2,233 meters) – when it was originally drilled in the 1960. Sustained production from the oil bearing sandstones was not established at that time.

In 2011, workover operations in the well were suspended when "junk" was encountered at the bottom of the well.

"We know that there are hydrocarbons in [Malolos-1]. Drilling in the well was however obstructed due to metals present in the well since 1960," a spokesperson representing Gas2Grid told Rigzone.

Gas2Grid's forward plan is to perforate and flow test the lower oil bearing sandstone intervals, followed by the shallower sandstone reservoir intervals that have been interpreted as being gas bearing.

Rig-1, the drilling rig for Malolos-1, is on Tuesday being prepared to mill out the "junk" in the hole. Oil and gas have been circulated out of the hole during current operations.
