| Kindly propose to your attention the list of questions which will be able to help to form the order and to perform the effective treatment of wells:
well construction (dimensions and intervals of lowering of all columns)
lowering interval of lifting pipe (dimensions)
setting of packer interval (in presence of packer)
temperature at bottom
salinity in liquid in well, mg/l
pressure at bottom
pressure at collar
pressure decrease from initial at collar (if such data are required)
initial well production (quantity of oil, gas and water)
the present well production ( quantity of oil, gas and water)
age of well
dead area of “rat-hole” (distance from low point of perforation till bottom)
known or estimated height liquid column in well (for the determination of water weight in case of necessity of its removal by foam)
Which is the reason of decreasing of intake capacity of injection wells in opinion of specialists of the oil-production enterprise?
Are the acid treatment of injection wells or other methods of increasing of intake capacity performed, if yes, which is the result?
Are the repairs of wells performed, if yes, was it noted the decreasing of intake capacity after each?
Was it noted the decrease of intake capacity over the period from moment of the last measuring of the current bottom till present time?
The specialists of NIC “ Nefteotdacha (Oil recovery)” – VNIIneft named after Academician Krilov (city of Moscow, Russia) carry out the technical support.
