Case Study
ESeal™ Liner Reduces
Water Cut in Marcellus
Challenge
A major east coast Operator needed to cover and isolate two sets of
perforations in the base casing. An ESeal Liner was chosen because
three previous liners were performing successfully in the same area for
this Operator. The perforations needed to be sealed so water influx
could be stopped to return the well to maximum production.
Elastomers 1,206 – 1,234
Perforations 1,258 – 1,262
Added Value
The Operator was able to reduce water influx and increase gas
production. The ESeal liner’s proven technology not only provided a
permanent solution, but also saved the Operator from costly NPT
associated with multiple cement squeezes.
