Fletcher Challenge begins drilling program in Brunei


Fletcher Challenge Energy Ltd. began drilling Apr. 15 its first exploration well in what is reported to be the biggest offshore exploration drilling program in Brunei for a decade. The well, Bendahara Selatan A-1 (BSA-1), is on Block BCD and will explore several targets at 1,360-3,700 m. The shallower horizons are thought to be potentially oil bearing, while gas and condensate reserves are more likely within the deeper horizons, said Fletcher Challenge.

The shallower horizons are thought to be potentially oil bearing, while gas and condensate reserves are more likely within the deeper horizons, said Fletcher Challenge.

While reserves estimates vary widely, the company postulates its share of mean potential reserves could be about 23 million boe, including other prospective undrilled structures in the vicinity.

Consistent with the wildcat nature of the well, Fletcher has assessed the probability of commercial success for BSA-1 at about 20%. Drilling is expected to take 33 days.

Interests in the well are operator Fletcher, 26.95%, and Unocal Corp., 26.95%, with Brunei partners holding the remainder.
