Life after wormholes

Propane injection in depleted CHOPS

WormholeCan you recover more oil from a field after a CHOPS project?

One operator is injecting methane-propane based solvent into an old CHOPS field using a single-well and multi-well patterns. They are studying the in-situ phase behavior at depleted and repressurized conditions. They hope to remobilize oil in wormholes.

Although the pilot has been running for some time, there is remaining uncertainty around the commercial viability of the process.
