This paper illustrates how the use of a Multifunctional Surfactant (MFS) can improve initial production and sustain production in under-pressurized, liquids-rich, tight sandstone (SS) reservoirs such as the Glauconite formation in West-Central Alberta.

BJ Services was presented with a unique opportunity to address changing operating conditions by applying new equipment engineering designs. More specifically, the company took a systemwide approach to engineering with the intent of delivering a new level of reliability and performance for clients.

Reducing friction is a long-established challenge that operators must overcome to decrease fluid flow friction and enable high-rate pumping without requiring more pressure generation at the surface.  Recent advances in polymer chemistry have led to the creation of polyacrylamide-based technologies that can provide a greater reduction in pipe friction and enhance proppant transport over conventional slickwater fluids.

A gelled fluid offers the benefits of being both temporary and easily cleaned up after the treatment. The objective in this application was to use a low cost gelled fluid to fully isolate existing perforations along a lateral to stimulate new zones. The novelty of this work included the application of using a gelled fluid in conjunction with a sliding sleeve system.
