There are a number of Wilcox Sands that that have not been not been completed including the sub-salt well that found a gas reservoir at a depth of 16,400 feet and beneath a 4,000 foot salt overhang. Most of the production today, however, has come from Miocene sands at a depth of about 10,000 feet. Since being drilled on the mid 1990’s these wells have produced over 18 billion cubic feet of gas.

Most of the past production at the Humble Dome has come from shallow cap rock sands. This field contains multiple reservoirs which means once one is depleted, new perforations can be shot into other zones to enable production from each well bore to continue. The average unit well production in the region is one million barrels (BOE).

Texas is a major hydrocarbon province and the state has the largest production of oil and gas in the USA. The State alone is ranked 8th in worldwide production. Significant production within the region of Cross Creek means there is existing infrastructure and extensive technical expertise providing lower costs than most places in the world resulting in lower opex and capex. Cross Creek is situated close to the largest refineries in North America which provides low transport costs for liquids and extensive pipeline network for gas transport.

During the mid 1990’s, Chevron leased over 2,000 acres over the western flank of the Humble Salt Dome. While holding the leases Chevron drilled ten directional wells, of which 9 are within the Cross Creek Leases, seeking flank gas production at a depth of about 10,000 feet.

Chevron sold the field in 1998. Since that time the leases have been owned by large companies with a drilling focus elsewhere. No rig workovers or recompletions to the next zones have been performed over the last twenty years. Cross Creek contains six producing wells. All of these wells have leaking tubing, plugged perforations and salt plugs that require remedial rig or coiled tubing work. In addition, the production history for these fracked wells shows precipitous drops in production that can be remedied through coiled tubing HF acidization work. There are also perforated zones available for fracking as well as unperforated sands in the Lower Wilcox A, Wilcox B and Wilcox C sand reservoir zones. Also the subsalt sand at a depth of 16,400 feet was drilled but never been completed. This zone has the potential for a high pressure, high rate gas and oil completion.
