REDUCE THE COST OF OIL PRODUCTION WILL A NEW STRUCTURE The foaming to kill the well, which has reduced the time of their master.
In the North Caucasus Research and Design Institute of Natural Gas in Gazprom created a foaming composition for killing wells, which is specifically designed for the conditions of abnormally low reservoir pressure, mainly distributed in the Russian oil fields.
Until now used in oil production fluids to kill the well, which has a low magnification and as a result a high density low blocking and high capacity filtration layer to it. This ensured a reduction in the natural permeability of the producing formations after release and ultimately lead to increased exploration wells.
V is the low magnification ratio of the volume of foam caused by the foaming liquid that is used as a foaming production waste isopropyl alcohol (CPIA) comprising low molecular organic substances having a low surface activity, which in turn increases the density of foam formed and does not effectively kill at abnormally low reservoir pressures (ANPD).
New foam-forming composition for killing wells, created the North Caucasus Research and Design Institute of Natural Gas, consists of foam concentrate based on an aqueous solution of lignosulfonate agent, a foam stabilizer - a hydrocarbon liquid, solid - a filler plant and water phases - an aqueous solution of calcium chloride, which contains as said mixture of particulate filler germs three day lignosulfonate barley powdery reagent.
This structure allows to achieve a result through which: increases its multiplicity and as a consequence reduced density while maintaining the sustainability indicators (stability), increased blocking properties of the composition and decrease its filtering into the formation by increasing the rate of formation of low-permeable filtration barrier, and maintains the natural permeability of the productive recovery after the release, which reduces development time and leads to lower costs of production, which in Russian conditions, so give oil at relatively high cost.
Any cost savings will play into the hands of Russian exporters of oil and it is important for the long term, when in times of adverse market conditions world oil prices reached the limit of cost. It was in this period of low prices ($ 8-10 per barrel), Russia gained the crisis in August 1998, as oil sold almost at cost or at a loss.
