摘要： A water-base wellbore fluid for use in subterranean wells that penetrate through a subterranean formation containing a shale which swells in the presence of water. The well bore fluid includes, an aqueous based continuous phase, and a shale hydration inhibition agent. One illustrative shale hydration inhibition agent is preferably the reaction product of a hydrogenation reaction of the product of the reaction of an aromatic amine with an aldehyde, preferably formaldehyde. Alternatively the shale hydration inhibition agent may be the reaction product of a hydrogenation reaction of the product of the reaction of aniline and formaldehyde. In one illustrative embodiment, the shale hydration inhibition agent is selected from the class of compounds known as polycycloaliphatic amines. The shale hydration inhibition agent may be present in the form of a free-base or preferably in the form of an acid salt of the disclosed amine compounds. The shale hydration inhibition agent is present in sufficient concentration to substantially reduce the swelling of shale drilling cuttings upon contact with the fluid.

摘要： A method of forming a subterranean well and a method of reducing the swelling of shale clay during the drilling of the subterranean well. The method features the use of a water based drilling fluid, wherein the drilling fluid is formulated to include: an aqueous based continuous phase; a weight material; an optional shale hydration inhibition agent and a shale encapsulator. The shale encapsulator has the formula: in which x and y have a value so that the molecular weight of the cation is in the range of about 10,000 to about 200,000 AMU; A is selected from C1-C6 alkyl, C2-C6 ether or C2-C6 amide; R, R′and R″are independently selectable C1-C3 alkyl; and B−is a charge balancing anion to the quaternary amine. The shale hydration inhibition agent and the shale encapsulator may be present in sufficient concentrations to reduce the swelling of the subterranean formation in the presence of water. Conventional additives may be included into the formulation of the drilling fluid, including: fluid loss control agents, alkaline reserve and other pH control agents, bridging agents, lubricants, anti-bit balling agents, corrosion inhibition agents, surfactants, solids suspending agents, and mixtures and combinations of these and other similar additives.

摘要： A novel process for making solutions of alkaline-earth metal salts of alkaryl sulfonic acids that contain about 1.5 to less than three weight percent water and that does not require an azeotropic distillation step to reduce the water of the reaction product to this level, comprises reacting an alkaryl sulfonic acid with alkaline-earth metal oxide in an organic solvent in the presence of 0.05 to less than 2.5 weight percent water. Calcium oxide, alkylbenzene sulfonic acids wherein the alkyl groups contain 10 to 14 carbon atoms, solvent mixtures of lower alkanols and non-polar hydrocarbon solvents all are representative of materials useful in the process of the invention, wherein the alkyl benzene sulfonic acid is preferably proportioned into a mixture of the other reactants and the water is supplied in admixture with a small amount of a calcium alkylbenzene sulfonate.
