Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1917 edition. Excerpt: ...the wells in the early fields in Pennsylvania had water standing in the hole when drilled and Quick observes that such wells produced more oil than has been the case since the practice has been to drill the wells in dry. The column of water in the hole provided a liquid seal that prevented the excessive escape of gas and consequently more of the energy was used in expelling oil from the pores in the sands. Moreover, the water prevented to a large extent the lowering of temperatures from the expanding gas and the vaporization of the gasoline in the oil which would have caused the deposition of paraffin and waxy sediment in the pores of the sand. The following method, described in Technical Paper 130,6 was first applied to gusher wells in California that, if allowed to flow unrestricted, would " sand up " or be likely to get beyond control: In some of the California fields wells capable of producing as much as 10,000 to 15,000 barrels of oil a day, and making in addition several million feet of gas, are restricted to a flow of 1,000 barrels a day or less, with a comparatively small flow of gas, by closing the well to a flve-eighths-inch or one-inch opening. It has been found that the ultimate flush production from such restricted wells has almost invariably been more than the unrestricted flow from neighboring wells. It is necessary to experiment on each well to find the size of opening for best results and from time to time this must be changed as conditions change at the well. / If the opening is too small only gas Quick, M.
