"and three months It costs about $30,000 to drill a well and as there are already 30 of them, means an investment of nine million dollars. The Humphreys Co is getting $12 per barrel, and others at about $1 25. If the Humphreys Co get 40,000 barrels each day for one year the value will be about 26 million dollars for 14,560,000 barrels. The surface rock is the Ordovay lime- stone having a thickness of about 170 feet. Then through the whole of the Upper Cretaceous. This limestone in the oil field is arched trending north and south. To the north it is thrown to the faulted more than once. The faulting goes through the whole of the Cretaceous into the Ordovay. As that is nothing younger we can gof say that the faulting is of just Ordovay age. This system faulting may be the cul- mination of the Balomas Fault. The blocks are set down to the east and raised to the west. The structure is about as in the next page.
