Saline composition “Betalock” is designed for preparation of heavy process liquids without solid phase, with the density of up to 1.61 g/cm3 (Grade A), 1.80 g/cm3 (Grade Б), and 2.1 g/cm3 (Grade В), correspondingly, used for preparation of operating fluids for drilling, well killing, perforations and conservation of oil and gas wells. It is a free-flowing granulated powder.
Retention of reservoir properties of formations and maintenance of well production rate due to absence of solid phase;
Multiple increase in successful jobs for installation and repair of the subsurface equipment, especially in deep holes;
Reduction of costs for its preparation.
Low corrosive activity and considerably lower cost (compared to the solutions of calcium bromide).
The saline composition of “Betalock” is completely soluble in fresh water. Its consumption rate depends on required density of solution. In case, some additional weighing of the solution is required, additional quantity of the “Betalock” composition is to be entered, with continuous mixing, before the entered saline composition is dissolved and the required density is obtained.
With the view to reduce its consumption rate, it is possible to use calcium chloride brine as a temporing liquid. The temperature of slump loss and crystallization would change at that.
