Challenge As production declined in a shallow oil well pumping at approximately 360 feet, an older jack pump became increasingly difficult to operate efficiently. Being a marginal producer, this aging system was performing too aggressively and exceeded what the low volume well could normally support. As a result, this excessive action disrupted the oil/water mixture […]
PISTON PUMPS REPLACE AIR LIFTS AT DEEP GASOLINE-SPILL PLUME TO RECOVER PRODUCT, NOT WATER
When a large gasoline spill in the Eastern U.S. produced a toxic plume 140 feet below surface, 11 popular-model air-lift pumps were installed in 4-inch-diameter wells to recover the product. But when the pumps brought up groundwater along with the product, the remediation engineer instead specified Blackhawk electric and pneumatic piston pumps.
The Blackhawks proved to be the only pumps that could reach the depth, pump the product without disturbing the formation (emulsification) and provide controlled drawdown and pump rates, according to the staff engineer for the environmental management and consulting engineering company contracted for the cleanup.
