PRODUCT DESCRIPTION
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.
The 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, it 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 the products also are good candidates as an EOR fluid in those cases where it is feasible to consider inter-well water injection and production.
FEATURES
(1) Reduce the oil-water interfacial tension, formation water to keep moist, thus reducing the oil flow resistance, to improve oil flow;
(2) Making heavy oil to form O / W type emulsion, reducing its viscosity;
(3) Changes in resin and asphaltene molecular structure to break down for the short-chain material, reducing its pour point and viscosity.
APPLICATION METHOD
(1) The principle of well-made
①The size of crude acid 1mg / l of crude oil
②Formation of residual oil saturation> 60%
③Formation water calcium and magnesium ions ≤ 350mg / l
④Formation clay content <8%
(2) On-site construction
①Preparation of 2% with water and heavy oil production agent
②Press the amount calculated radius of 2.0 ~ 3.0mm
③Backwashing with water wells 1 to 2 weeks
④Good yield with a pump will be prepared to squeeze into the strata agent, shut-18h after the open wells.
PACKAGE
25kg plastic drum, no special transportation requirements.
