摘要： This invention relates to a new and novel method for the underground storage of fluid materials including those which are readily soluable or reactive with water or brine such as concentrated caustic soda, ethylene dichloride or anhydrous ammonia within chambers developed in salt formations via solution mining and from which essentially all the brine has been removed; and the chambers thereby produced. More particularly this invention relates to methods for making underground storage chambers; of recovering the brine formed in the making of the chamber; isolating the contaminants, i.e., the insolubles mixed with brine resulting from the solution mining of the storage chamber, such that fluids soluable or reactive with water or brine can be stored therein; and also to a method for controlling the velocity of free fall of materials injected into the chamber for storage, such that erosion of the equipment employed is minimized.

摘要： A nondamaging work over and completion fluid having water soluble bridging agents includes a saturated brine solution having at least one water soluble salt which is insoluble in the saturated brine solution and having particle size range of about 5 microns to about 800 microns and wherein greater than about 5% of the particles are coarser than 44 microns. Viscosifier and suspension additive is added to provide the desired viscosity and assist in maintaining the water soluble sized salt suspended in the saturated brine solution. If desired or necessary a fluid loss control agent may be added to enhance the fluid loss control or filtration control of the completion fluid.The invention may be practiced by pumping or discharging the fluid or a slug or pill of the fluid into an oil, gas, water, injection or storage well where operations are to be conducted in which it is desired to temporarily plug the permeable zone while such operations are carried out. Thereafter, the water soluble bridging agents are removed by connate water from the permeable zone, or a nonsaturated brine wash, or ordinary water circulated in the well.

摘要： A new method for making large underground storage caverns in bedded or domal salt deposits for the storage of fluid materials in areas where solution mining water temperatures are low by a process which significantly reduces the amount of time required to make equivalent sized underground storage caverns and which is economically feasible and friendly to the environment. The process includes the warm water solution mining of the underground salt deposits in a manner which conserves the heat contained in the supernatant brine from the underground cavity and employs this heat as a significant source for warming the water employed in the solution mining operation.

摘要： A non-damaging well drilling fluid contains a polysaccharide, a lignosulfonate, chrome sulfate, a pH modifier and, preferably, graded calcium carbonate and starch. The fluid is effective to seal off the well bore essentially immediately and is non-damaging in that it causes little permanent plugging of the formation by loss of the drilling fluid solids to the formation.
