Product: Capillary Suspension Fluid
Using Trican’s CSF Frac fluid system, we were able to enhance proppant transport, allowing the placement of larger and more conductive sand at higher concentrations. By using our new chemical system our customer reduced costs on three fronts:
Our customers came to us with a concern – they wanted to get more out of their reservoir and reduce costs in the process. They needed a simple, cost-effective means of transporting high concentrations of sand to their fracture and a system that could operate without damaging the proppant pack. Trican’s Capillary Suspension Fluid (CSF) was designed with these considerations in mind.
Our customers had been using traditional guar-based crosslinked gelled water fracture treatments. While effective, these traditional guar-based crosslinked gels also have their drawbacks:
The Trican Solution
Capillary Suspension Fluid (CSF) is a cleaner breaking, cost-effective replacement for crosslinked guar systems. CSF is composed of two main parts that work together:
This system capitalizes on the capillary forces and lattice structure that is created by the MVP and synthetic polymer combination to support the proppant in the pipe and out into the formation. The optional addition of nitrogen to the system adds a stepwise increase in these properties.
While traditional guar gels need water heated to approximately 35°C to encourage hydration of the gel, CSF uses a synthetic polymer that can hydrate in any water temperature. As a result, this system only needs to be heated to about 5°C, which translates to substantial cost savings, especially in winter.
Guar gels also need high quality water in order for crosslinking reactions to occur. CSF has no such restrictions - to date, we have yet to receive a water sample that CSF is unable to gel. This includes high brine and produced water samples. With the increased focus on water consumption in Canadian fracturing operations, CSF helps to reduce the associated costs by allowing producers to reduce their fresh water procurement and trucking costs.
The Trican Advantage
Using Trican’s CSF Frac fluid system, we were able to enhance proppant transport, which permitted the placement of larger, more conductive sand at higher concentrations. Using our new chemical system our customer reduced costs on three fronts:
This reduction in ancillary costs resulted in significant savings for the customer.
