Wymagane parametry cieczy roboczych dla ochrony pierwotnych właściwości skał zbiornikowych
(2008) Uliasz, Małgorzata; Herman, Zdzisław
Before the workover or stimulation operations are started the well must be filled with so-called completion fluid which hydrostatic pressure overcomes reservoir pressure and protect against reservoir fluid flow into the well. The completion fluids are mixtures of artificial salt solution and filtrated reservoir waters. The authors discussed properties of completion fluids which were prepared in OGI laboratories.
