US unconventional oil output is estimated to jump 144,000 b/d in June to 7.178 million b/d, the US Energy Information Administration said Monday in its Drilling Productivity Report, the biggest month-on-month increase in the four-and-a-half years since the agency has published the report. The Permian Basin of West Texas and New Mexico appears slated for the largest increase by far at 78,000 b/d, for a total 3.277 million b/d of oil output, EIA said.
