Eagle Ford Wells
Eagle ford wells
START Energy deploys RASA’s Polar Selective Agent (PSA) to rejuvenate declining Eagle Ford wells – delivering more oil, less water, and sustained production using the infrastructure already in place.
key points_
Production rises – and keeps rising
Oil volume climb while water declines. A sustained shift driven purely by in-reservoir chemistry.
Triggers a dramatic, reservoir-wide chemical shift
Oil becomes lighter, new gas species form, and mineral load in produced water drops.
Works through existing infrastructure
Deployed through the existing wellbore using standard equipment and the natural fracture network.
90% more oil. 90% less water
start rejuvenates the reservoir
START production keeps climbing
Conventional EOR is a pressure game – inject, push, peak, decline. In ultra-low permeability formations like Eagle Ford, aggressive methods create brief production spikes that collapse just as fast. No technology has delivered sustained incremental recovery to justify the investment.
START has. In their first Eagle Ford deployment, oil production increased more than 90% while water production fell more than 90% – and results continue to climb after 100+ days.
What START has achieved is not “better EOR.” It is something not previously observed in petroleum engineering: reshaping a reservoir’s chemistry downhole, increasing production output, and producing cleaner, more refined oil that is richer in light hydrocarbons.
a basin in decline,
is a basin in play
The Eagle Ford is one of the most prolific shale basins ever developed – but the vast majority of its wells are now mature and in decline.
Of the 19,100 producing wells, 12,200 (64%) yield less than 20 barrels a day. That’s a problem. That’s the opportunity.
