Clarksville field, Red River County, Texas; Production and facies interpretation

Clarksville field was discovered in December 1985 by a well targeting a deeper Paleozoic horizon. Since production began in 1986, this field has produced more than 1 million bbl of oil with the appearance of a considerably longer and more lucrative life. The producing horizon is a Jurassic age lithic conglomerate sitting unconformable on the Paleozoic and Triassic structural front of the buried Ouachita range. Facies correlation out of the basin indicates this unit to be Louark age. Mapping and compositional analysis indicate the depositional environment of this unit to be an arid climate alluvial fan deposited as a bajada complex. This fan system was laid down at the updip margin of the actively forming Mesozoic embayment where it meets the Ouachita structural front. The significance of this field is demonstrated by the production yield at a relatively shallow depth of 5,800 ft. At this time, similar production to Clarksville field is yet to be encountered anywhere along the Mesozoic rim of the East Texas basin but does represent a viable exploration trend, in addition to being the gateway for future Paleozoic production in the basin.
