    Conventional chemical product development has been based on the guidance from chemical intuition and conventional wisdom, which often results in lengthy laboratory testing based on laborious trial-and-error procedures. In the field, the performance of chemicals in specific applications may vary significantly over time and due to different geological and reservoir environments. Optimizing performance of the chemicals under different reservoir conditions usually requires substantial molecular structural modifications, with respect to which a better fundamental chemistry understanding via theoretical insights can have an important beneficial impact.

    Chemeor Advance Molecule 2
    ChemEOR’s unique approach to product development utilizing molecular design combines the experts’ knowledge, novel laboratory evaluation procedures, and advanced computational simulation techniques to obtain quantitative correlations of the molecular structure of chemicals and the performances in different applications. In particular, a series of modern molecular modeling methods, including Quantum Mechanics (QM), Density Functional Theory (DFT), Molecular Dynamics (MD), as well as Quantitative Structure-Activity Relationships (QSAR) and Quantitative Structure-Property Relationships (QSPR) approaches, have been applied routinely to guide our experimental efforts for faster and better product development.
  • Surface Chemistry

    IMG 4181 1 2 Cropped
    Surfactants (Surface Active Agents) are usually organic chemicals that have both oil and water soluble components in their structures. A solution containing a surfactant and/or a mixture of surfactants can therefore reduce the oil-water interfacial tension (IFT), or alter the wetting tendency of the reservoir rock surfaces.

    Oil & Rock

    •   Spontaneous imbibition
    •   Surface wettability


    Improved Oil Recovery | CRS®

    A novel suite of surfactant formulations designed to increase oil recovery at low concentrations (0.05%-0.2%), especially in fractured carbonate and unconventional (especially shale) reservoirs.

    •   Penetrates into matrix porosity to displace and mobilize the oil for improved production.
    •   Improves flowback.
    •   Enhances non-emulsification.
    •   Customized for different oil fields and basins, such as Lost Hills, Bakken and Eagle Ford.

    Bio & Nano Technology
    Bio and nano materials are also used for surfactant formulations, rendering the unique properties such as micro-emulsion, bio-degradability and higher hydrocarbon recovery ability.

    Water & Rock

    •   Wettability change
    •   Reduces capillary force


    Flow-Back | FB

    Field proven, high performance surfactant formulations added in stimulation fluids to increase the drainage speed (dewatering) of the injected fluid.

    •   Greatly accelerates the flow back process and recovers a large volume of injected fracturing fluid.
    •   Reduces water blockage to stimulate more oil production.

    Oil & Water

    •   Interfacial tension reduction
    •   Emulsification


    Non-Emulsifier | NE

    Field proven, proprietary surfactants added into stimulation fluids to increase the separation of produced oil and water post stimulation.

    •   Discourages tight oil-water emulsions.
    •   Improves flowback.
    •   Reduces emulsion blockage and formation damage.
  • Fluid Rheology

    Polymer Blend
    High molecular weight water soluble polymers are produced in dry and inverse emulsion forms. When added in the aqueous-based fluids, such polymers can improve their flow and rheological properties. A unique dry polymer process allows fast, complete, fisheye free hydration. In addition, no degradation of molecular weight is seen with this process. Inverse emulsions and dispersions are available when dry polymers are not desired. These polymers can be tailored for specific brine and temperature applications.

    Flow Improvement

    •   Decreases the energy loss
        (pressure drop) in turbulent
        flow (friction)


    Friction Reducers | PUMPex®

    Fast-hydrating, high-performance dry friction reducer functioning at low dosage (0.1 – 0.2%) for stimulation fluids in low to medium salinity brines.

    •   Logistic advantages (easy transporting and stable storage).
    •   Environmentally benign (No organic or harsh solvents).
    •   Add on the fly (hydrates and achieves maximum performance in less than a minute).

    Viscosity Control

    •   Increases fluid viscosity and
        carrying capacity
