Wireline Cased Hole Services increases a wells longevity.• Helps well owners understand the well and the reservoir• Done to optimize lifetime full production potential

• Minimizes risk proactively• Identifying and fixing problems during completion and

production

• Look beyond immediate well environment• Monitor fluid distribution & movement• Track fluid fronts

Five SpinnersA conventional spinner (left) only measures flow in the center of the wellbore. The Flow

Scanner spinners (right) measure the flow at five points across the vertical axis

Schlumberger provides oil production equipment and

services for a reservoir’s entire life cycle.

Therefore, Wireline Cased Hole Services is used during a

reservoir’s entire life cycle.

Cased Hole Services: Maximizing Recovery

• Production Logging

• Perforation

• Pipe Recovery

• Well Integrity

• Reservoir Evaluation

What are the different techniques to perform these operations?

Preparation:• Casing and cementing• Chose the log and services you find necessary• Perforate the casing• The detecting wire is ran after the well has

been cased or lined with production pipe.
