East Texas - JRC/Lisa Layne

The JRC-Lisa Layne operation is located on the southeast edge of Quitman, Texas, and is comprised of mature oil developments in the Paluxy and Sub-Clarksville formations. Prolific mature producers, these high water-cut wells are lifted using high-volume electrical submersible pumps (ESP).

Current lifting capacity is approximately 10,000 blpd. Production fluids are separated at two facilities, and associated salt water is disposed of using three Sonoran-operated injection wells. Facilities reliability was recently enhanced with the replacement of steel disposal lines with high-pressure fiber-reinforced epoxy lines, with the replacement of aged water settling tanks, and with the addition of a high-rate centrifugal injection pump.

Further facilities enhancement continues. The majority of the wells possess the potential to produce at significantly higher production rates, and options are under review to increase the liquid handling capacity of facilities, and the addition of one or more disposal wells.

East Texas - Ann McKnight

The Ann McKnight unit is located just to the east of Tyler, Texas. The reservoir consists of high-permeability Paluxy sands running generally north-south, dipping to the south. The field was initially produced naturally, followed by gas-injection pressure maintenance at the up-dip end of the field, and finally through water-injection pressure maintenance down-dip of the producers.

The high water-cut production is separated in a central facility, and produced water is pressurized for reinjection at a Sonoran-operated injection well. Both electrical submersible and rod pumps are used in the producers. To improve separation efficiency and operational reliability, the central facility was relocated closer to the producers and processing equipment was enhanced.

Current producers possess the capacity to produce at significantly higher levels, and a significant inventory of inactive wells may offer re-entry potential as both producers and as additional pressure maintenance wells. These options are under review.
