The EFB D-24 well at East Flour Bluff was targeting sands with an estimated 3P (proven, probable and possible) reserves of 31 billion cubic feet.

The well indicated that the field will meet and even exceed reserves expectations, Sun Resources managing director Brad Farrell said.

Six separate reservoirs have log-indicated gas pay, and overall reserves look like being significantly higher than predicted, he said.

While wire-line data analysis indicated the secondary target was unlikely to be economic, the 3,688 metre-deep well should produce four to six million cubic feet of gas per day from multiple zones in the Frio sands without fraccing, according to Farrell.

The well is being plugged to the base of the casing at 3,386 metres for commercial production.

EFB D-24 evaluated the field’s potential as part of a two-well program and mirrored the recently completed B G Webb-1 well, which successfully evaluated the adjacent West Flour Bluff field.

In addition to the 31bcf 3P reserves at East flour Bluff, about 67bcf of recoverable gas is estimated to be in the Frio Massive, J and K sands under the Laguna Madre sea lagoon covering West Flour Bluff.
