IN-HOUSE STIMULATION TECHNOLOGY

CHRONOFLUX

Delayed Acid System for Carbonate Reservoir

An in-house formulation by the TII team designed to dissolve the rock matrix and enhance flow using a non-diesel delayed-acid stimulation system, helping to achieve deeper penetration into the reservoir and maintain better flowback after stimulation.

02 / WHY CHRONOFLUX

Advantages

04 KEY POINTS

Non-diesel system

Uses a specially formulated hydrocarbon blend (NAF) and does not use diesel.

Corrosion & stability

Exhibits lower corrosion, a more stable acid system, and a better safety profile compared with diesel-based acid systems.

Delayed reaction

Delays acid–rock contact through a stable water-in-oil (W/O) emulsion.

Wormhole development

Generates deeper wormholes with lower PVBt, as stated in the source poster.

03 / REPORTED RESULTS

Performance

LABORATORY + FIELD
In Laboratory Scale

Stability, efficiency & corrosion: ChronoFlux demonstrated superior stability, efficiency, and reduced corrosivity compared with conventional HCl acid systems in lab testing.

Wormhole efficiency: Improves wormhole efficiency and enables deeper acid penetration compared to conventional HCl.

Potential improvement: Potentially reducing the skin factor to −4 to −5 or increasing production by 44%.

Potential skin factor−4 to −5
Potential production increase44%
