Thanks, Mark. Good morning, everyone. We appreciate your interest in W&T and we thank you for joining us on our second quarter 2012 earnings conference call. Here with me today are several members of our management, including Jamie Vazquez, our President; Danny Gibbons, our Chief Financial Officer; Steve Schroeder, our Chief Technical Officer; and I'd also like to introduce Tom Murphy, who joined W&T in June as Senior Vice President and Chief Operations Officer.
Tom obtained a BS in Petroleum Engineering from the Colorado School of Mines. Over the last 28 years, he's gained extensive operating and management expertise, while working at companies such as Woodside Energy, PetroQuest, Devon and ARCO. He's held a variety of engineering, operational and commercial positions domestically and internationally, onshore and offshore, including Gulf of Mexico deepwater and the onshore unconventional plays. Steve Schroeder has agreed to take on the newly created position of Chief Technical Officer, where he can lend his technical expertise to the company, with specific focus on our acquisitions and other special projects.
Now historically, during our quarterly conference calls, various members of our management team deliver prepared remarks regarding our quarterly results and operating activities. This quarter, we thought it would be a bit more efficient to include a lot of the information in the earnings release that we would normally provide in our conference calls to facilitate your review and understanding. This way, you have the information in advance, which should help facilitate a more active question-and-answer session.
So we're assuming you've had a chance to review the release we put out yesterday. And hopefully, we'll spend most of our time on this call addressing your questions. I'll provide a brief review of some of the quarter's key highlights and I'll update you on current events and plans then we'll be happy to take your questions.
So let's get started. In the second quarter, we had another strong performance, with production volumes averaging 48,600 barrels of oil equivalent per day. That's up 6.8% from the same time last year. Volume dropped this year as a result of the acquisitions that we did last year with not only the West Texas properties, but also the Fairway Field acquisition. Additionally, we continue to have good success with drill bit in the Gulf of Mexico, as well as in West Texas. In fact, second quarter production came in around expectations despite the downtime we experienced during the quarter.
Between the third-party pipeline outages that happened in April and the downtime associated with Tropical Storm Debby, we deferred about 2,200 barrels of oil equivalent per day. For most of July, we were producing around 49,000 barrels of oil equivalent per day. We're currently experiencing some downtime at Matterhorn due to a third-party pipeline outage that's expected to be a short-lived event. In fact, their guys tell us that's probably going to be online this weekend. Regardless, we are reaffirming our prior full year guidance. Those guidance details are in the earnings release.
So good things are happening. We've been successful at focusing on crude oil and our production mix. In the second quarter, oil sales represented 71% of total revenues, while NGLs represented 12% and natural gas represented 17% of total revenues. In our Deepwater Matterhorn field located in Mississippi Canyon 243, we've increased production 75% in the past 12 months. That's going from 3,390 barrels of oil equivalent per day net in July of 2011 to 6,027 barrels of oil equivalent per day net in July of 2012, as a result of drilling the A-4 sidetrack well and recompleting the A-7 well. We own 100% of this oilfield.
At our Mahogany field located on the shelf in Ship Shoal 349/359, we've increased production 115% in the past 12 months with our ongoing drilling program. We basically took it from 1,921 barrels of oil equivalent per day net in July of 2011 to 4,139 barrels of oil equivalent per day net in July of this year. As a result of drilling 3 wells, the A-11, A-1 sidetrack and the A-13 wells. This doesn't include the A-5 sidetrack wells that we anticipate will come on production later this week, adding about another 900 barrels of oil equivalent per day to our production. We own 100% of this oilfield as well.
We were apparent high bidder on 11 of 13 bids made in the recent OCS sale held on June 22, 2012. That exposed approximately $2.8 million and $2.5 million in high bids. We'll continue to add prospects to our prospect inventory using lease sales and third-party submittals, both on the shelf and in the Deepwater Gulf of Mexico, as well as our own existing acreage inventory.
In West Texas, we've successfully decreased the drilling days per well from 23 to 12 in our Yellow Rose field. This is about a 50% improvement in our rig utilization. We're well ahead of schedule on our lease obligations. We've made fundamental well-design changes, as well as significant time reductions by using newer technology rigs and top drive systems. We've also drilled our first horizontal well in the field. We're in the process of performing a 20-stage frac treatment.
Further to that, we're making strides in improving our completion methodology to improve recovery and production rates in the field. We currently have 7 wells waiting on frac treatments and see the opportunity to further increase field production by streamlining our timing from rig release to frac treatment. As a reminder, we currently have reserves booked on only 80-acre spacing for the Wolfberry, so there's still a lot of upside in the field with downspacing and with the potential results of our horizontal well, which is currently in the completion phase.
In East Texas, we've completed our second well of a 4-well delineation program. The well is currently flowing back, we're on schedule to complete the 4-well program in 2012, which will provide the information needed to determine if we want to launch a development program in 2013 on our 143,000 acres. We believe this project has tremendous upside. All of our 2012 budgeted wells are currently on schedule. That puts us in really good position.
We expect to see a continuing transformation onshore in both West and East Texas. We expect to be in at least one other basin onshore. We expect to spud a deepwater exploration well in the third or fourth quarter this year. Finally, we expect more acquisitions in the not-too-distant future. We note that the bid-ask spread has been too high since the fall in prices this year, but we're seeing a plethora of assets for sale. We think that there will be more M&A activity in the second half of this year and beyond. W&T is very well-positioned with about $600 million in liquidity.
With that operator, I'll open up the lines for Q&A.
