Gulf Coast Region
Our development, exploitation, exploration and production activities in the Gulf Coast region are primarily concentrated in southeast Texas. This region is managed from our office in Houston, Texas. Principal producing intervals are in the Wilcox, San Miguel, Olmos, and Yegua formations at depths ranging from 3,000 to 12,500 feet. We had 233 producing wells (143 net) in the Gulf Coast region as of December 31, 2019, of which 125 wells are operated by us. Average net daily production in 2019 was 348 Boe. At December 31, 2019, we had 726 MBoe of proved reserves in the Gulf Coast region, which represented 5.1% of our total proved reserves. We maintain an acreage position of over 12,700 gross (5,120 net) acres in this region, primarily in Dimmit and Polk counties. We operate a field service group in this region from a field office in Carrizo Springs, Texas utilizing four workover rigs, nineteen water transport trucks, two saltwater disposal wells and several trucks and excavating equipment. Services including well service support, site preparation and construction services for drilling and workover operations are provided to third-party operators as well as utilized in our own operated wells and locations. As of March 31, 2020, the Gulf Coast region has no operated wells in the process of being drilled, no waterfloods in the process of being installed and no other related activities of material importance.
Mid-Continent Region
Our Mid-Continent activities are concentrated in central Oklahoma. This region is managed from our office in Oklahoma City, Oklahoma. As of December 31, 2019, we had 418 wells (216 net) in the Mid-Continent area, of which 144 wells are operated by us. Principal producing intervals are in the Roberson, Avant, Skinner, Sycamore, Bromide, McLish, Hunton, Mississippian, Oswego, Red Fork, and Chester formations at depths ranging from 1,100 to 10,500 feet. Average net daily production in 2019 was 840 Boe. At December 31, 2019, we had 2,094 MBoe of proved reserves in the Mid-Continent area, or 14.7% of our total proved reserves. We maintain an acreage position of approximately 55,880 gross (10,690 net) acres in this region, primarily in Canadian, Kingfisher, Grant, Major, and Garvin counties. We operate a field service group in this region from a field office in Elmore City, utilizing one workover rig and one saltwater hauling truck. Our Mid-Continent region is actively participating with third-party operators in the horizontal development of lands that include Company owned interest in several counties in the Stack and Scoop plays of Oklahoma where drilling is primarily targeting reservoirs of the Mississippian, and Woodford formations. As of March 31, 2020, in the Mid-Continent region, the Company was is participating in the drilling and/or completion of four wells, with overriding royalty only in eight additional wells, all included as Proved Undeveloped in the 2019 year-end reserve report.
West Texas Region
Our West Texas activities are concentrated in the Permian Basin in Texas and New Mexico. The Spraberry field was discovered in 1949, encompasses eight counties in West Texas and the Company believes it is the largest oil field in the United States. The field is approximately 150 miles long and 75 miles wide at its widest point. The oil produced is West Texas Intermediate Sweet, and the gas produced is casing-head gas with an average energy content of 1,400 Btu. The oil and gas are produced primarily from five intervals; the Upper and Lower Spraberry, the Wolfcamp, the Strawn, and the Atoka, at depths ranging from 6,700 feet to 11,300 feet. This region is managed from our office in Midland, Texas. As of December 31, 2019, we had 522 wells (257 net) in the West Texas area, of which 298 wells are operated by us. Principal producing intervals are in the Spraberry, Wolfcamp, and San Andres formations at depths ranging from 4,200 to 12,500 feet. Average net daily production in 2019 was 3,703 Boe. At December 31, 2019, we had 11,108 MBoe of proved reserves in the West Texas area, or 78% of our total proved reserves. We maintain an acreage position of approximately 19,910 gross (12,560 net) acres in the Permian Basin in West Texas, primarily in Reagan, Upton, Martin and Midland counties and believe this acreage has significant resource potential for horizontal drilling in the Spraberry, Jo Mill, and Wolfcamp intervals. We operate a field service group in this region utilizing nine workover rigs, four hot oiler trucks, one kill truck and two roustabout trucks. Services including well service support, site preparation and construction services for drilling and workover operations are provided to third-party operators as well as utilized in our own operated wells and locations. At December 31, 2019, the Company had committed to participate in the drilling of ten Proved Undeveloped horizontal drilling locations. Seven of the nine wells were drilled by April 15, 2020, but are not expected to be completed and producing until the fourth quarter of 2020.
