In the East, we continued the development of the Baker-Deforest Unit with the number 5H, number 6H and number 7H falling 3,200; 3,560 and 4,115 barrels of oil per day with 3.5, 4.1 and 4.4 million cubic feet per day of rich gas respectively. We also began development of several new acreage units with the completion of the Justiss Unit number 1H, number 2H and number 3H falling 3,885; 3,560 and 3,940 barrels of oil per day, plus 4.4, 5.0 and 5.6 million cubic feet per day of rich gas respectively.
In addition, the Vinklarek Unit number 1H was completed flowing 4,510 barrels of oil per day with 5.9 million cubic feet per day of rich gas. EOG has a 100% working interest in each of these western wells.
As noted on our second quarter call, we continue to test downspacing patterns in both the East and West. The downspacing process takes time. The ultimate goal is to maximize oil recovery in the net present value of the acreage.
In summary, EOG's Eagle Ford position and operational team are proving to be the most powerful oil growth offense in North America. Quarter-by-quarter, this asset continues to get better and better. We have many years of drilling inventory in this high rate of return play.
Now, shift to the Bakken/Three Forks. We continue to see outstanding results from the technical renaissance in frac technology that we started in 2012, in conjunction with our downspacing program in the Core.
Recent downspaced wells in the Core include the Van Hook 126-2523H and 130-2526H with initial production rates of 2,235 and 1,910 barrels of oil per day, plus 1,115 and 900 Mcf per day of rich gas, respectively. The Wayzetta 137-2226H and 150-1509H which began producing 2,500 and 2,320 barrels of oil per day with 1.2 and 1.1 million cubic feet per day of rich gas, respectively.
In the Antelope Extension area, we completed three excellent Three Forks wells in the first bench. The Bear Den 100-2017H, 101-2019H and 23-2019H began flowing 2,100 and 1,235 and 1,665 barrels of oil per day, plus 2.0, 1.2 and 1.6 million cubic feet per day of rich gas respectively. We are encouraged by the Three Forks potential in the Antelope area. We completed and excellent well in the second bench early this year and planned to test the third bench during 2014.
We are now achieving direct a-tax rate of return in excess of 100% in both the Core and Antelope areas. We added two new slides to the IR presentation showing EOG's outstanding 2013 results.
Page 23 shows EOG's 2013 completions at 58% more production in the first 100 days as compared to those completed in 2012. The same slide also shows the year-to-date IP rates from these two areas are up 50% as compared to last year.
Page 25 shows EOG compared to 20 different Bakken operators. EOG's average IP this year is 1.9 times better than the peer average. With a modest drilling program, we are growing all volumes and setting new production records.
On our second quarter call, we increased our drilling inventory in the Bakken three-fourth, from seven to 12 years. With excellent results and a large inventory, we anticipate increasing drilling activity in the Bakken/Three Forks in 2014.
