What's new in exploration
A big Brazilian find. Petrobras announced a huge discovery north of Campos basin, with estimated reserves of at least 600 million boe. This was the result of appraisal drilling, when a horizontal extension, Well 3-ESS-110HPA, drilled last month by the Noble Paul Wolff, tested 3,000 bpd of 17°API oil. Calculations indicated that production could have been as high as 20,000 bpd. A six-month extended well test will now be conducted using the largest ESP ever installed, with over a 20,000-bpd capacity.
