WY/Rockies drills far exceeding expectations/ JV w AET.UNfrom DVN 1st q Operations Report, page 18, 5/5/15 release,, JV w Argent in Powder River/WY "Rockies" where 2 rigs operate,.. Bea............. Raising Powder River Basin Type Curve Expectations: Devon brought 11 development wells online during the quarter targeting the Parkman and Turner formations in Campbell County, Wyoming. Initial 30‐day production rates from these wells averaged almost 1,400 Boe per day, of which more than 80% was light oil. A recently enhanced well design drove these outstanding results. The company’s new design uses extended‐reach laterals of 9,600 feet, more than 2 times the lateral length of the previous design. With strong results from the well design changes, Devon is raising its type curve in the Parkman Focus Area. Initial 30‐day production rates for these extended reach development wells are expected to be about 150% higher than the previous design, at an incremental cost of only 45%.
