Control Line Sealing

Why is this a challenge?

A leaking control line is mostly useless and can be a source of leak and pollution. More problematic is that a control line at some stage will be a possible leak path for pressure moving from one depth to another. It can also be a breach of well control barrier in a well.

This is how we seal Control Lines

The Wellcem resin has extremely low viscosity and even at low temperatures can the resin be pumped through a small control line and thousands of meters down in a well.

It is normally a one-man job easily done in a few hours with very little equipment and chemicals. The chemicals are normally mixed on site and only a few liters are normally needed. The surface lines are flushed clean after the resin has been pumped to ensure no resin is left at surface.

The carefully controlled curing time allows for secure placement and the control line can normally be tested the next day to ensure it holds and the line is secured.

The testing is normally done by the same engineer with the same equipment that has been used for pumping the resin into the line. The pressures test is recorded and submitted to the operator together with a full end of job report.
