The average daily production from our developing fields was 2,222 Boe per day (32% of our total daily production) in 2009, and an increase of more than 2% over the previous year. We drilled a total of four gross (3.0 net) wells in our developing fields, all of which were completed as wells capable of production. An additional five gross (1.2 net) wells were drilled to their objective depth and awaiting completion or pipeline connection at year end. As of December 31, 2009, the proved reserves in our developing fields were 13 MMBoe and account for 39% of our total proved reserves. Our most significant developing fields are as follows:
South Texas. During 2009, our net daily production from our South Texas properties averaged 1,463 Boe per day and make up 30% (10.0 MMBoe) of our total proved reserves. We drilled three gross (2.8 net) wells in our La Copita field in Starr County, Texas. All completions were successful with initial production rates up to 650 Boe per day from the Vicksburg formation. We are the operator of all of the wells in our La Copita field and our 2009 drilling program added another three new proved undeveloped locations. We have allocated $22.0 million of our 2010 budget to South Texas.
Barnett Shale—Jack and Wise Counties Texas. We drilled two gross (0.4 net) wells on our Tier 1 Barnett Shale acreage in 2009, with one gross (0.4 net) well completed as a producing well and one gross (0.04 net) well in the process of being completed at the time of this report. Our net average daily production from our Barnett Shale wells was 718 Boe per day during 2009 (approximately 10% of our total average daily production for the year). We have a large acreage position within a Participation Agreement with Devon Energy Corporation in which we have the right to participate with a 36% working interest in all wells proposed in the contract area. A total of 21 gross (7.4 net) wells have been drilled since the inception of the agreement. As of December 31, 2009 we estimated our proved reserves in our Tier 1 Barnett Shale area to be 2.1 MMBoe, or 6% of our total proved reserves. Approximately $3.0 million has been budgeted for drilling in 2010 in our Barnett Shale play.
