Completion Fluids | Care for the Oilfield Industry

Completion Fluids | Care for the Oilfield Industry As the oilfield industry is soaring new heights with each passing day owing to the increase in demand of the petroleum based products today, simultaneously, the need of completion fluids is also escalating with same pace.

Amongst the completion fluids, the most commonly used components are Completion 14.2™, Completion 12.5™ and Completion 19.2™. Consequently, there is a rising demand for the preparation of these chemical components or rather the completion fluids in order to cater to the needs of the oilfield industry for carrying out the drilling operations required in oil and gas exploration projects.

Useful Fluids: Generally, the brine solutions of zinc, sodium and calcium blended with bromides and chlorides are useful for such oil drilling purposes because of the high density and solids-free nature of such solutions. Quite a similar composition is therefore maintained

Specification of Completion 14.2™: The Completion 14.2™, which is chemically a calcium bromide solution (52%) is a common completion fluid used extensively as a completion and work-over fluid for controlling the wellbore pressures during the upstream oil and gas exploration operations. It can be used as a single solution as well as mixed with calcium chloride and/or zinc/calcium bromide in order to get a clear and solids-free fluid that is prepared over a varied range of density and crystallization temperatures. It is usually a colorless liquid and sometimes a light yellow transparent liquid having a specific gravity of 1.70 grams/cm.cube and a density of 14.2lbs/gal. It is a water soluble component and is also available as dry powder on request.

Fluids for Drilling Purposes: Another Major Completion Fluids popularly used in Oil and Gas Drilling exploration projects is the Completion 12.5™ fluid. Chemically, this is sodium bromide solution (45%), having a formula of NaBr.nH2O. Apart from serving as a completion and work-over fluid for drilling purposes, its other characteristics include:  It is colorless, odorless and transparent liquid, resembling sodium chloride solution.  It is used as a single salt and is applicable in those purposes where the density requirement ranges within 8.4lbs/gal to 12.8lbs/gal and where the formation waters have high amount of bicarbonate and sulfate ions.  In addition to being used as a single-salt solution, this can also be used in collection with the sodium chloride solutions to get an optimum density range of 12.8lbs/gal. In fact, keeping in mind the economic factors for the oil and gas exploration projects, the NaBr/NaCl multi-salt solution is more beneficial than that of the single-salt counterpart.  Powder form of the chemical can be given on request.

Apart from the above two, there is another Completion Fluid in the run, which is known as the Completion 19.2™. It is actually zinc bromide solution and chemically composed of two types of salts, namely the Calcium Bromide & Zinc Bromide Solutions. Similar to the other completion fluids, this is also a clear and solids-free liquid having a density of around 19.2lbs/gal. Along with these features, it is also non-damaging, thermally and chemically stable and can be used as a multi-salt additive.

Hence, all these completion fluids are in high demand and therefore manufactured in plenty.
