SCALE INHIBITION IN HIGH PRESSURE AND HIGH TEMPERATURE APPLICATIONS

Abstract:

Methods are provided to inhibit scale formation in oil or gas production systems. In one embodiment, the scale inhibiting treatment comprises: A) an AAA terpolymer and B) a polycarboxylate such as a polyepoxy succinic acid (PESA). The treatment can be added to these systems in the well area itself, to the well annulus and its associated tubes, casings, etc., to the oil or gas bearing subterranean formation, to injection conduits for injection of steam or fracking fluid to the subterranean formation, to the produced water, or to equipment in fluid contact with the produced water.
