A method and apparatus for generating electricity from a generator driven by the flow of fluid flowing from a fluid producing well. A fluid driven motor is positioned in the pipeline adjacent to or above the well head such that the fluid passes through the motor to turn the motor shaft to drive the generator. By controlling the electrical load connected to the generator, the force required to drive the motor and thereby the pressure reduction across the motor can be controlled. The electricity produced by the generator may be used to heat the fluid in the pipe to prevent freezing of the fluid. The electricity can be utilized to heat the emulsion in an emulsion separator dehydrator for separating gas, water, and oil prior to its introduction into the pipeline. Separate motor may be utilized for gaseous fluid and liquids. Where the well produces both gas and liquid a separator is employed to separate the gas and liquid.
A method of stimulating production of hydrocarbons from a well capable of production from oil and gas bearing strata wherein a desiccant is delivered through the well to dehydrate the well and a zone around it and then an anhydrous carrier for an anhydrous acidizing agent such as hydrogen chloride, hydrogen fluoride, or carbon dioxide is injected at a pressure sufficient for the gaseous materials to permeate through the strata and react with connate water to form a mixture of carbonic, HCl, or HF acids which will react with rocks forming the strata to increase the permeability of the strata and thereby stimulate production from the well.

A method of stimulating production from an oil well capable of primary production of an oil bearing strata, comprising the steps of injecting liquid carbon dioxide down the bore of the oil well at a pressure sufficient for gaseous carbon dioxide, formed by the evaporation of the liquid carbon dioxide, to permeate through the strata and react with connate water to make carbonic acid. The well is then shut in for a period of time enabling the carbonic acid to react with the rocks in the strata to increase the permeability of the strata and thereby stimulate production from the oil well.

Abstract:
A method of stimulating production from an oil or gas well comprising the steps of (a) injecting a desiccant through the well bore to dehydrate the well bore and a production zone within several feet around the well bore, (b) injecting an anhydrous acid into the production strata, the anhydrous acid being formulated to be gaseous at bottom hole temperature and pressure so that the gaseous anhydrous acid permeates through the dehydrated production strata and dissolves in connate water to form an acidic solution, and (c) shutting in the well for a period to allow the acidic solution formed in situ to react with the materials of the formation thereby increasing the permeability of the production strata and stimulating production from the well. A alcohol/polyglycol desiccant with exceptional lubricating, heat stability, and corrosion inhibiting characteristics is used to dehydrate the well and to form a corrosion resistant film on surfaces of the production string and casing.
