New Chemical Treatment for in-Depth Conformance Control

The objective of this project is to evaluate new chemical formulations that will increase flow resistance to water in high permeability steaks. Desired effect is to divert water into lower permeability zones where oil has been bypassed during previous waterflood operations.

Sand pack made into a 20-ft coil and loaded into a Blue M oven

Pressure transducers are placed to transmit readings every 5 feet. Data collected and processed on a PC.

Precision ISCO syringe pump delivers test fluid at rates as low as a few micro-liters/min

A typical result for a successful chemical where there is a substantial increase in pressure compared to water only (circa 1 psi). The pressure "wave" works its way down the 20-foot long pack as the chemical slugprogresses.
