Significant drop of fluid rate after the water shut off job for isolation of flow behind casing from underlaying water formation

Reperforation and near-wellbore stimulation jobs were unsuccessful

Proximity of water zone

High content of asphalt-resinous paraffin deposits

Drilling of 2 radial channels 45 ft. length each

The accuracy of the well position using the Perfobore inclinometer was confirmed by Perfobore specialists and the client

Multipoint acid treatment was carried out inside the drilled channels. Acid composition was washed through the Perfobore’s jet nozzle at various points of channels: 12% HCl (Volume of HCl – 151 bbl)

Oil increment: 162 bopd

In case of BHP=485 psi (as was before Radial Drilling)

Increasing of PI by 6 times

Post-job skin: -5,9

Oil increment is 380 bopd. After 8 months the well is performing with an oil rate 2X to a pre-job level
