Heavy Oil Recovery Agent
Heavy oil generally is defined as having an API (American Petroleum Institute) gravity of 10-20 degrees API. These crude oils have viscosities ranging from the 1,000’s to over 1,000,000 cp at reservoir conditions. This tremendously elevated viscosity means that it has a very high resistance to flow, even in a reservoir with high permeability formation rock.
HORA products are customized blends of nonionic surfactants designed to increase the recovery of heavy oil. These agents mobilize heavy oil in place via an emulsification mechanism, low interfacial tension (IFT), and reducing the effective oil viscosity. As highly efficient viscosity reducers, HORA can achieve their superior performance at low dosage (typically 1 -5 gallons per thousand gallons, gpt) in a neutral or caustic solution, and this aqueous surfactant/alkali treatment solution is contacted with a heavy oil 3 to 4 times larger. Their wide compatibility with brines and other chemicals in oil field operation and good stability towards elevated temperature and salinity assure its extensive applicability in various conditions. Caustic solution containing HORA products also are good candidates as an EOR fluid in those cases where it is feasible to consider inter-well water injection and production.
