摘要： A resistive cable-based well heater for providing heat to an oil or gas bearing formation includes a length of coiled tubing having a sealed down-hole end and an open-ended cable support adapter attached to the up-hole end of the coiled tubing. A bundle of cables is contained within the coiled tubing. The cables extend from the upper opening of the adapter and have free upper ends. A wedging tube is placed in the open end of the adapter to support the cables against the interior sidewall of the adapter when the well heater is deployed in a well. The wedging tube has an inner surface shaped to conform to the shape of one or more of the cables and an outer surface configured for weight bearing frictional contact with the inner sidewall of the cable support adapter.

摘要： An apparatus for installing two sensing instruments and cables inside of a single tubing string in a wellbore for monitoring well conditions at two different locations includes an upper sensor attached to an inner sleeve seated at a first location in a ported outer sleeve in the tubing string. The upper sensor is allowed to be in pressure communication with the exterior of the tubing string at the first location. A second lower sensor is deployed on a pump down cup (PDC) assembly to a lower depth in the outer sleeve to allow fluid pressures to be monitored at a second location in the wellbore.

摘要： A method for desalinating and recycling the brine exiting a salt cavern. This method reduces the overall make-up water demand to wash a salt cavern, eliminates the brine disposal well and controls the cavern growth rate during disposal operations. The method includes the steps of: a) desalinating brine emerging from the salt cavern, and creating a stream of saline water, a stream of non-saline water and a stream of salt; b) recycling the stream volumes and combining the stream of non-saline and saline water with make-up water, thereby reducing demand for make-up water, c) pumping the salinated water into the salt cavern, and controlling the rate of growth of the salt cavern while disposing of wastes in the cavern, and repeating steps a) and b) substituting the make-up water with a waste mixture.
