Areas of Operation
Tengasco Inc. has 171 active 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 20,971 acres under lease containing 14,261 acres held by production (HBP) and 6,710 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. Of these, Rooks County contains 58% of the Company’s actively producing wells.
The Company had Net Oil reserves of $2,817,000 Bbl (proved) at YE2009. Kansas accounted for 91% of the Company’s revenue and 92% of the Company’s total production. Tengasco’s total production from Kansas is 600 barrels per day.

Swan Creek Field
Hancock County, TN
Situated in the Appalachian thrust belt, the Swan Creek field was discovered by Amoco in the 1980’s. Tengasco began exploration and development of this field in 1997 and currently has four producing oil wells and twenty-one producing gas wells. The field produced 104,043 MCF of gas and 6,396 Bbl of oil in 2008, and has total cumulative production since Tengasco began operations of approximately 3.2 BCF of gas and 200,000 barrels of oil. Other potential exists in the near-by area for Devonian shale exploration for gas, along with continued interest in drilling other structures similar to Swan Creek for oil and gas.
The Company’s wholly-owned subsidiary, Tengasco Pipeline Corporation (“TPC”) owns and operates a 65-mile intrastate pipeline constructed to transport natural gas from the Company’s Swan Creek Field to customers in Kingsport, Tennessee. In 1996, the Company began construction of a the pipeline to connect the Swan Creek development project to a gas purchaser and enable the Company to develop a gas transportation business in the future. Phase I of the pipeline construction was a 30-mile portion of the pipeline that was completed in 1998. Phase II, the remaining 35 miles, was completed in March 2001.
The pipeline transports gas from both Swan Creek and the MMC Carter Valley project to the Kingsport market. Although TPC’s 65-mile system is a common carrier pipeline, it currently has limited transportation revenue from third party producers or pipelines, but is open to providing access for those parties with pipeline quality and quantities of gas available for transportation.
