EOG’s High-Density Sand Volumes Pay Off

By The Bakken Magazine Staff | April 30, 2014

Ongoing improvements in drilling and completion techniques have transformed what was a steady development drilling program for EOG Resources’ Bakken and Three Forks assets, “into a high-rate-of-return crude oil growth play,” according to the exploration and production pioneer. The company has gone to a completion design based on shorter fractures in combination with high-density sand volumes. The new design has yielded huge results.

EOG’s well production averages for its 30-day initial production rates in 2013 were 50 percent higher than the previous year because of the completion design. In 2012, IP rates for EOG’s Bakken wells averaged 894 barrels of oil per day, but in 2013, the average IP rate for Bakken wells reached 1,342 bopd. In the first 100 days of production, 2013 wells recorded a 63 percent increase over the previous year.

EOG’s 90,000 net acres in the core of the Bakken are showing strong infill IP rates with shallower declines as well, according to the company. All new wells will be completed with the high-density frack sand, short frack interval method. And, the sand will be sourced from an EOG-owned facility based in Texas. This year, EOG will use six drilling rigs, drilling roughly four wells per section. The company has already received positive tests from testing in the first and second benches of the Three Forks formation. Testing on the third bench of the Three Forks will take place this year, and EOG plans to drill 80 net wells by year’s end.
