Areas of Operation
Tengasco Inc. has approximately 180 producing wells in Kansas, with the majority located on the Central Kansas Uplift and adjacent west flank. The Kansas subsurface is divided into five basins that are separated by uplifts. Basins are characterized as thicker sedimentary rock packages than those found on the uplifts. The western third of Kansas is underlain by the Hugoton Embayment of the Anadarko Basin. This basin is very deep in Oklahoma with depths exceeding 40,000 feet and shallows into Western Kansas.
The Central Kansas Uplift separates the Hugoton Embayment from the Salina and Sedgwick Basins of Central Kansas. The Central Kansas Uplift is a structural high that trends from northwest-southeast and is the largest structural feature in Kansas. A map showing the oil and gas fields of Kansas clearly shows the impact of the structural features on the distribution of oil and gas deposits. Production on the uplift primarily comes from the Lansing/Kansas city Group and the prolific Arbuckle Group. Production on the west flank trending into the Hugoton Embayment comes from the Cherokee Group and Mississippian age rocks. Other geologic units provide minor amounts to production totals.
Focusing on central Kansas, Tengasco currently has approximately 27,000 gross acres (approximately 22,000 net acres) under lease containing approximately 14,200 gross acres (approximately 11,800 net acres) held by production (HBP) and approximately 12,800 gross acres (approximately 10,200 net acres) not HBP in various stages of development. Exploration and Development drilling in Kansas has been focused on, but not limited to, ten central counties on the Central Kansas Uplift and on the west flank.
The Company had Net Oil reserves of approximately $877,000 Bbl (proved) at December 31, 2015; of which Rooks County accounted for approximately 64%. During 2015, Tengasco’s gross oil production from Kansas was approximately 158,000 Bbl; of which Rooks County accounted for approximately 62%.
