Well flowback or cleanup is a well operation by which fluids remaining in the wellbore and subsurface as a result of drilling, completion or stimulation operations are recovered or returned to the surface via natural flow or a lifting methodology. The overall objective is to leave the well ready for production. This operation is sometimes combined with production well testing to further evaluate the reservoir and well production potential.
AccessESP offers a unique industry solution to effectively handle well flowback or cleanup services by including the AccessESP Permanent Completion (dock) as part of the well completion that will eventually host the retrievable ESP to perform the flowback or cleanup operation. Once it’s complete, the ESP can remain in the well, providing the needed artificial lift support.
For cases where the well initially will produce with natural flow, the retrievable ESP can be removed riglessly on a live well (providing a full bore access to the lower completion for various interventions such as perforating or through-tubing bridge plugs). When the well energy declines, the ESP can be easily reinstalled permanently – again riglessly, through tubing, on a live well.
The rigless retrievability of AccessESP allows for an efficient pump changeout or motor resizing to adapt to well performance changes – and eliminates the need to kill the well.
As part of our flowback services, we provide a full well flowback design and operational workflow and controls, which are easily integrated with production well testing services.
Our highly trained and multiskilled engineers and service technicians work collaboratively with our customers and other stakeholders to gather well and operation information, perform service design, mobilize, run the flowback or cleanup, and then demobilize. We provide 24/7 service and support to ensure full compliance with QHSE policies, while maximizing operation efficiency at a much lower OPEX.
