Providing of environmental safety during oil well completion

Authors: R.M. Vafin (Nafta-Service LLC, RF, Almetyevsk), A.A. Saltykova (OIL INDUSTRY Publishing House CJSC, RF, Moscow), A.S. Bubnov (Research and Innovative Technology Research Expert Company, Tomsk Polytechnic University of drilling, RF, Tomsk), S.V. Vorobyev (Samara State Technical University, RF, Samara), R.V. Dvoretskas (Perm National Research Polytechnic University, RF, Perm)

Key words: production well, sidetrack, quality cementation, environmental safety, completion.

One of the main problems of environmental safety during construction and operation of oil wells is the preservation of tight lining and insulation permeable reservoirs along the borehole in secondary completion fluids to prevent behind-casing and cross-flow between layers flows. Slotted abrasive jet perforation is proposed to reduce the risk of negative effects on the environment during the perforation of sidetracks. Сlassification and analysis of the sources of environmental pollution during drilling are performed.
