Definitions
- the CaBr2' is mainly supplied as a 52% CaBr 2 solution and in a solid state which contains 95% CaBr 2 .
- a 52% CaBr 2 solution is saturated below -10°C.
- the melting point of the solid state CaBr 2 is about 700 °C, and it is highly hygroscopic. In the open air, the solid CaBr 2 absorbs air humidity and dissolves.
- ppg Calcium Bromide is a standard solution. If a fluid having a lower density, e.g. 13 ppg is needed for a specific well, it can be obtained e.g. by adding Calcium Chloride solution having a density of 11.8 ppg (a standard solution) or by adding water. If a fluid having a higher density is needed for another well, a higher density fluid may be added, such as Calcium Chloride Solid (94-97%). Depleted brines, having too low a density, can be returned to the desired density by the addition of Calcium Bromide or a sufficiently concentrated solution of Calcium Bromide, but this is often not economical. It is also possible to add Calcium Chloride Solid to the depleted brine, but this will result in a fluid with a high True Crystallization Temperature (TCT)
- TCT True Crystallization Temperature
- Solid CaBr 2 hydrates having a concentration of CaBr 2 of not less than 65% (hexahydrate) and no more than 78%, i.e. near to the equivalent of trihydrate, and preferably from 70 to 75%.
- Their density is not less than 2.1 gr/ l, and typically between 2.15 and 2.3 gr/ml. All the percentages in this description and claims are by weight, unless otherwise specified.
- Another aspect of the invention is a process for raising the density of Calcium Bromide solutions by adding CaBr 2 hydrates to said solutions. This is particularly useful when the Calcium Bromide solutions are depleted and therefore do not have the density required for their use.
- the expression "Calcium Bromide solutions” includes solutions containing salts other than Calcium Bromide, particularly Calcium Chloride. Said process includes adding, besides CaBr 2 hydrates, other density raising additives, e.g. Solid Calcium Chloride or solid Calcium Bromide or high concentration solutions of this latter.
- a further aspect of the invention is the use of solid CaBr 2 hydrates for preparation of clear brines (completion fluids, work-over fluids, drill-in fluids) in the processing of oil wells and the like, in soil remediation (remedying contamination of a subsurface environment) or for any other use, and their use for restoring already used and therefore depleted drilling fluids (completion fluids, work-over fluids, drill-in fluids) to or close to the desired, original density, and for any other use.
- restoring used drilling fluids by the addition of fresh solution it is clearly important to use materials as concentrated as possible, in order to reduce/minimize the solvent water that will be introduced as part of the operation.
- the drawing is a diagram showing the True Crystallization Temperature (TCT) of returned fluids as a function of density.
- CaBr 2 crystallizes in a few hydrate forms.
- the common forms are tetra- and hexahydrate.
- the hexahydrate contains 65% CaBr 2
- the tetrahydrate contains 73% CaBr 2
- the trihydrate 79% CaBr 2 .
- the existence of di- and trihydrates is questionable and they are mentioned as hypothetical species.
- the hydrates are solid in ambient temperature, and their melting/saturation point rises with the decreasing number of water molecules.
- Table 1 details the calculated molecular weight and concentration of CaBr 2 (%) of CaBr 2 hydrates.
- the hexahydrate CaBr2.6H 2 0 melts at temperatures below 40°C, and is not convenient as it may melt during storage and/or delivery. Its specific gravity is 2.1. The melting point of the tetrahydrate CaBr 2 .4H 2 0 is 80°C. Its specific gravity is 2.2.
- Table 2 gives the specific gravity and melting point of a number of CaBr 2 solutions having different concentrations.
- Option 2 Using CaBr 2 tetrahydrate with 73.5% CaBr 2 , 4.5 ton of depleted brine may be used - 3 times more than when using the 52% solution.
- the amount of CaBr 2 52% exceeds by far the amount of the depleted brine, so that the upgrade is hardly practical.
- the advantage is especially big when the real amount of solution needed for the application is similar to the amount of the depleted brine.
- all specific gravities are calculated at 20°C and all percentages are by weight. Fluids having specific gravities (S.G.) above 1.71 are considered herein as high density fluids.
- Table 3 illustrates the dependence of TCT, density and the volume increase of the returned fluid (14.2 ppg CaBr2 which was reduced to 13 ppg by addition of CaCl2 solution (11.8 ppg)).
- the density was corrected (raised) with CaCk Solid.
- the units used in the Table can be converted as follows: to convert gr/ml to ppg, multiply by 8.33; to convert ml to gal, divide by 3780.
- CaCl 2 Solid can be used to reach a density of about 1.59 gr/ml. However, at a density of about 1.61 gr/ml the TCT is 11.6°C, which would limit the fluid to use as summer blend only; Table 3
