Using chemical tracers to optimise choke position and drive maximum production from a multi-stage horizontal well

The application of chemical tracers in a multi-stage horizontal well, allowed one operator to gain insight on stage productivity in order to plan an optimal field development strategy.

The Challenge

Staying competitive in a low-cost environment has driven operators to have a laser focus on the critical reservoir and completion factors that maximise the barrels produced per dollar spent. In order to be a top basin producer, it is increasingly important to remove uncertainty in how to optimise stage number and spacing, well spacing, cluster strategy, water and proppant usage, and effective cleanout. Yet the trial-and-error approach of the past provides feedback too slowly to optimise drilling and completion costs and maximise Estimated Ultimate Recovery (EUR).
