Screenless Sand Control Completions

Overview Library

Chemical consolidation and proppant packs

Screenless completions use chemical consolidation treatments and proppant packs with proppant-flowback control additives to keep formation sand and proppant from entering the wellbore. The technique eliminates the skin associated with screens and gravel packs and provides full wellbore access. It is applicable to both remedial and new well completions.

Oriented perforating

Oriented perforating optimizes phasing, hole spacing, and orientation of the perforations.

Chemical consolidation

Chemical consolidation treatments produce a bonding reaction with formation sand to keep the sand from entering the wellbore.

TSO fracturing treatment

During the tip screenout (TSO) treatment, a resin-coated proppant is pumped into the fracture. A fiber additive can be pumped in the last stages of the fracture treatment to keep the proppant from flowing back into the well.
