Thank you, Tracy. In 2011, we once again set goals for growth and profitability and our staff had executed and delivered on that strategy. Reserves, production and profits are up. We were successful in our efforts. We accomplished these results by making the right acquisitions, by operating our assets effectively to increase production, by keeping our reserve replacement cost under control, and by executing a very successful drilling program of 8 offshore and 46 onshore wells with a success rate greater than 98%.
Let's talk about operational activities and first talk about Gulf of Mexico. As a significant part of our total asset base and source of cash flow, the Gulf of Mexico continues to be a focus for the company and a source of acquisitions, as well as exploration and development projects. The Fairway acquisition, along with our exploration development program in 2011, have provided us profitable opportunities, which have excellent rates of return and low funding and development cost. In 2011, we had 100% success rate in drilling our 8 offshore wells, which include 3 exploration and 5 development wells. Our offshore exploration and development programs will continue to play an important role in achieving our production and reserve goals going forward.
During the fourth quarter, we successfully drilled 4 offshore wells, all located on the conventional shelf, 2 were development and 2 were exploration wells. Two of the wells were at Mahogany field, where we drilled Ship Shoal 349 A-1 exploration well and a 349 A-11 development well. These are 2 -- first 2 of the potentially 6 well drilling programs at the Mahogany field that commenced in 2011 and will continue into 2013. Both of these wells were drilled about 14,500 feet TVD, targeting oil in the P Sand, which is the main producing zone for the field. These wells are currently producing 2,115 barrels of oil per day and 7.5 million cubic feet per day gross. As you recall, we have 100% working interest in this field.
The other 2 offshore wells included the South Timbalier 41 E-1 exploration well and the South Timbalier 315 A-3 development well. The South Timbalier 41 E-1 well in which we have a 40% working interest was drilled to a measured depth of 16,300 feet and found gas pay in 2 sands. The well is currently producing 2.7 million cubic feet per day and 100 barrels per day net to our interest. The South Timbalier 315 A-3 well in which we have a 50% working interest was drilled to a total measured depth of about 13,000 feet and found oil pay. The well is currently producing 170 barrels per day and 240 million cubic feet per day net to our interest. This well is part of a broader work development program for the field, with an expected increase in total production from the field of 380 barrels per day and 507 million cubic feet per day.
In 2012, we plan to continue our development program at the Mahogany field, drill 5 exploration wells from the shelf and drill 2 wells in the deepwater, one of which is an exploration well.
At the Ship Shoal 349 Mahogany field, we are currently drilling the A-13 well, which is expected to add 1,500 barrels of oil equivalent per day of net production in the third quarter. The 5 exploration wells in the shelf have an average working interest of approximately 56%, and the wells will be located in water depths anywhere from 33 feet to 430 feet, targeting reservoirs anywhere between 9,000 feet and 15,400 feet. The total cost of the wells to drill, complete and hook up is expected to be in the range of $50 million to $70 million net, depending on our working interest.
In the deepwater, we are currently rigging up to drill the Mississippi Canyon 243 A-4 sidetrack well, which is a development well targeting an oil sand. This well is expected to produce 3,500 barrels of oil per day, net to our interest. The total estimated cost of the well is $47.6 million net.
We also plan to drill a non-operated exploration well, targeting oil in the deepwater. This well is expected to spud sometime in the third quarter of 2012. We will provide more information about the well when we get closer to the actual spud date. We believe that you will be excited, as we are, about this prospect once we can fill you in on the details.
Let me give you an update on the onshore activity. Currently, our focus is on both West Texas Permian Basin and on East Texas. In the Permian Basin, we have actively exploring and developing in 2 distinct areas, with approximately 30,000 net acres under lease. We will continue to evaluate potential bolt-on acquisitions to increase our lease acreage in the area. Currently, we have 3 rigs exploring and developing the 21,500 net acres we acquired in May of last year, which we referred to as our Yellow Rose Properties. Since May until the end of 2011, we drilled 29 vertical wells to total depth in the Yellow Rose Properties, of which 8 were exploration wells. In 2012, we will continue with a 3 rig drilling program to explore and develop the Yellow Rose Properties. While we expect to drill 46 development wells, we also expect to drill 6 vertical and 3 horizontal wells in this area, which should prove up additional reserves.
As a reminder, our proved reserves are based on 80-acre spacing. At the end of 2011, on our Yellow Rose Properties, we had 174 drilling locations based on 80-acre spacing. At the end of 2011 -- excuse me, 80-acre spacing. At the end of 2011, our Yellow Rose Properties, we had 174 drilling locations based on 80-acre spacing that were pad location. We have another 279 drilling locations that are associated with probable reserves using 40-acre spacing. Therefore, there are 453 remaining drilling locations using 40-acre spacing.
In addition, pending well results evaluation, there is a lot of additional upside available if we choose to further down space to 20 acres and/or drill additional horizontal wells, as seen by nearby operators. The cost of each vertical well to drill and complete is running around $2 million. We are targeting about 4,500 feet of vertical section in the Wolfberry.
As we disclosed in our recent operational update press release, we anticipate the average vertical well will yield a 26% IRR, assuming flat pricing of $90 per barrel of oil and $3 per Mcf for natural gas, using 163,000 barrels of oil equivalent per well estimated ultimate recovery gross. The initial full month production rate is expected to be approximately 51 to 90 barrels of oil equivalent per day gross. In mid 2012, we plan to begin our pilot test horizontal program with the drilling of a horizontal well in the field.
In Terry County, we successfully drilled 13 exploration wells in 2011 to test and evaluate prospects. These wells targeted the Wolfberry at a depth of about 12,000 feet, with an estimated cost of $2.3 million per well. Currently, we're at various stages in the completion and flowback of these exploration wells. Although the results are encouraging, we are still within our exploration and delineation phase. We plan to continue to analyze the data received from those wells and will most likely drill a couple of horizontal wells in the Terry County prospects prior to announcing our future development plans. We also have a large number of drilling locations in Terry County, but right now, we are focused more on the potential horizontal opportunities. It's important to realize that on this play, consisting of about 9,500 acres, we do not have any proved reserves booked related to Terry County prospects. So obviously, there's a lot of upside opportunity for reserve and production growth in 2012 and beyond.
Now let's go on to the other side of Texas to East Texas other than -- which is our other focus area. In East Texas, we have 2 prospective exploration areas. One area, which we refer to as our Star Project, consists of 6 East Texas counties. And the company now controls approximately 141,700 net acres in this area that is solely focused on the James Lime. In 2011, we drilled a horizontal exploration well to test and target the James Lime formation at approximately 8,000 feet total vertical depth. The well has been completed and is currently flowing back. This well is 1 of 4 exploration wells planned to delineate the project. In 2012, we anticipate drilling 3 additional horizontal wells, which should provide sufficient data to determine future development plans. The estimated cost per well is $6.4 million with a targeted IP rate of 833 barrels of oil equivalent per day gross. Our drilling obligation for this project is approximately 3 wells per year to hold the majority of the acreage, which provides us adequate time and flexibility to explore and develop this project as we feel most appropriate.
The second project area in East Texas targets both conditional and unconditional reservoirs. In 2011, we drilled and completed a vertical exploration well, targeting the Cotton Valley. We call this our Branton East Prospect and we own 35.4% working interest in it. The initial production of the well has been delayed due to higher than expected H2S content. Once this well has been fully tested, we will report the result and future plans that we may have in the area.
Let's talk and give an update on the 2012 capital budget. As previously disclosed, the capital budget for 2012 is $425 million, excluding acquisitions. And this is up 37% over 2011 budget and will fund a larger exploration development drilling program. The 2012 budget currently anticipates the drilling of 10 offshore wells and 65 onshore wells, with $167 million for exploration activity and $258 million for development activity. Most all of the budget is directed to oil and liquid-type projects. It should be noted that the company has historically drilled within cash flow and most of the time has operated completely within its cash flow. As we stated in our operational press release in January, we have a reserve growth goal of at least 18% for 2012 over year end 2011 reserves of 117 million barrels of oil equivalent.
In summary, we have had a very successful 2011 and we're ready to do it again in 2012.
With that, I'm going to turn it over to Steve to give you an update on some other operational items.
