Unconventional Multi-Frac Wells – Reservoir Characterisation and Optimising flowback operations

A customer wanted to test two different lithologies and compare the performance of both, in the gas window of the Neuquén Basin. For that reason, a slanted two-horizon target well was drilled, distributing 10 stages in the upper zone, and 10 stages in the lower zone. 

21 unique organic gas and water tracers were added to each of the different stages of the well during stimulation. The injection was controlled and care was taken to tag all stages in the same way, ensuring that the tracers would penetrate deep into the fracture structure and make contact with formation hydrocarbons.

Download the Case Study using the form opposite and learn how subsequent flowback and sample analysis for the presence of the injected tracers, allowed relative gas and water flow from the different stages to be evaluated, thus enabling the customer to determine if all their stimulation efforts were effectively producing.
