Preparations to Drill the Horizontal Clayton # 1H Well In Runnels County, Texas Are Now Under Way

VANCOUVER, BC / ACCESSWIRE / May 28, 2015 / CARDIFF ENERGY CORP. (the “Company”) (TSX-V: “CRS”) is pleased to announce that site preparations for drilling of the Clayton # 1H including pad construction and digging of pits are being completed to allow the rig to move in and commence drilling. With the site preparations underway the estimated drilling date of the Clayton # 1H is June 15, 2015.

The Clayton # 1H will target the Gardner Lime. The Gardner Lime is a fractured limestone which is approximately 15 feet thick and comparable geologically to another major field in Texas called the Austin Chalk. The Austin Chalk has had a number of successful horizontal wells, of which some of the more prolific wells have had initial production of 1500 barrels of oil per day (BL/day). The Clayton # 1H will be drilled to a depth of approximately 4100 feet with a horizontal leg of up to 3500 feet. A frac is not required as the oil will flow through the limestone fractures. This will allow the Company to avoid the expensive frac process to release oil from the ground; with the potential for oil production being attained at a lower cost than average producers.

The Clayton # 1H is a joint venture between the Company, (who will take 2/3) and Martin Energies, the Operator, (who will take 1/3). The Clayton # 1H will be drilled adjacent to the Bearcat #4. Martin Energies, the Operator states, “To be part of this project means being in on the ground floor of a major discovery. By drilling one horizontal well the results could be the equivalent of 5-7 vertical wells”.

In addition, it has been determined that the Bearcat #4 is capable of producing more natural gas than was expected. Therefore, management has decided to tie both the Clayton #1H and the Bearcat #4 gas production together at completion. Currently the Bearcat # 4 is on minimal production to retain gas reserves until the pipeline connection can be made.
