Marathon Oil reported earnings today and impressive Eagle Ford results accompanied the news. Marathon has driven Eagle Ford drilling times down to 24 days across its acreage and has increased the number of wells it expects to drill by 20 to 250-260 in 2012.

"Our investment in the Eagle Ford shale a little more than a year ago, and our bolt-on acquisitions since then, continue to deliver value beyond original expectations. Not only have we improved the speed and efficiency of our drilling and completions there, we also continue to optimize well spacing which could significantly increase drillable locations and recoverable reserves.

Marathon's Record Well

In the quarter, Marathon drilled 78 wells and brought 73 to production. With one of those completions, Marathon brought on a well that came close to EOG's Record Eagle Ford Well. The Burrow 2-H in Gonzales County produced at a peak 24-hour rate of 6,275 boe/d. Almost 75% (4,646 boe) was attributable to oil and condensate.

The record well contributed to impressive production growth too. Production in the third quarter averaged approximately 40,000 net boe/d - 33,000 b/d of liquids and 46 mmcfd of natural gas. That's up from 18,000 b/d and 18 mmcfd in the second quarter. As of November, production had reached 60,000 net boe/d, a 50% increased from the third quarter average!

Marathon also closed a previously announced deal for 4,300 net acres in South Texas for $232 million. The deal added 40 net drilling locations and 2,900 boe/d of production.

EOG Resources' Eagle Ford assets continue to deliver. The company brought on the largest producing well in the play to date in the second quarter. The Gonzales County Boothe Unit #10H came on line at 4,820 bpd of oil, 972 bpd of NGLs, and 4.5 mmcfd of natural gas. That's more than 6,500 boe/d from one well. Better yet, the Boothe Unit #9H, an offset well in the same unit, produced over 4,600 boe/d when it came online.

Drilled from the same pad as the Boothe wells to minimize costs, the Dreyer Unit #19H and #20H were turned to sales at initial rates of 3,703 and 2,650 Bopd with 460 and 300 Bpd of NGLs and 2.1 and 1.4 MMcfd of natural gas, respectively. EOG has 100 percent working interest in these four wells.

Enterprise Expansions Add Marketing Options for EOG

The company expanded its marketing options when the Enterprise's Eagle Ford Crude Oil System came online over the summer. The 24-inch oil pipeline gives the company direct access into the Gulf Coast refinery market. Enterprise also commissioned a natural gas processing plant being utilized by EOG.

EOG's net production in June 2012 averaged more than 103,000 boe/d. The company is largest oil producer in the play. With wells coming online at more than 4,000 b/d, the Eagle Ford is driving production growth for the entire company. EOG increased its crude oil production growth target from 33% to 37%. A few other highlights include:

  • EOG will also continue to test down spacing across the play. 65 to 90-acre test have had very strong results and tighter spacing tests are in the works.
  • Self-sourced sand and frac crews are also providing a strategic advantage. The company estimates it is making an 80% after tax rate of return on its investments in this arena
  • 330 net wells will be drilled in 2012
  • 20 rigs will run through the remainder of the year - Down from an average of 26 in the first half of the year
  • Average number of drilling days per well has dropped to 14
