    Earth Pro PAC

    Earth Pro PAC is a primary fluid-loss reducer for water-based drilling fluids and also serves as a suspending agent.

    This polymer’s highly polyanionic nature grants it shale stabilizing properties by binding to positive sites on formation substrates, forming a protective barrier. These suspension properties are crucial in maintaining formation pressure and ensuring consistent performance across different drilling applications.

    A bag of regular polyanionic cellulose polymer. The bag is black and has the text: “PAC-R API Spec Regular PAC. Industrial grade. Rheology and filtrate control for water-based drilling fluids. 22.68KG Net weight. For industrial use only.”
    A bag of low-viscosity polyanionic cellulose polymer. The bag is green and includes the text: “PAC-LV API Spec low vis PAC. Filtrate control for water-based drilling fluids. 22.68KG net weight. For industrial use only.”

    Earth Pro PAC Properties

    Not only is Earth Pro PAC a fluid-loss reducer for water-based drilling fluids, but it’s also a suspending agent that stabilizes viscosity. Here are some key properties you need to know about this polymer.

    Physical Properties

    Appearance: Off-white powder
    Specific Gravity: 1.5
    Flash Point: Not available
    Auto-Ignition Temp: 170°C

    Chemical Properties

    Type: Cellulose fluid loss polymer
    Solubility: Soluble (forms gel)
    pH: 6 – 8.5
    Microtox (Regular): > 600 kg/m3
    Microtox (LV): 10 kg/m3

    Packaging & Controls

    WHMIS: Not controlled
    TDG: Not regulated
    Packaging: 50lb sack


    Regular and low-viscosity grades of Earth Pro PAC are applied at concentrations ranging from 3.0 to 10.0 kg/m3 in salt-based mud systems, while freshwater-based mud systems typically use concentrations between 1.0 and 3.0 kg/m3

    Earth Pro PAC is also compatible with oxygen scavengers, allowing its use at temperatures reaching up to 150°C.

    Mixing & Handling

    We recommend storing Earth Pro PAC in a dry location. When adding it to fluid environments through the hopper, gradually pour it for 30-40 minutes per sack to help prevent lumping.

    Additionally, wearing a dust mask and eye protection is advisable while mixing all powdered products.


    Earth Pro PAC is available in two grades: PAC-R (regular) and PAC-LV (low-viscosity).

    PAC-R not only reduces fluid loss but also contributes to secondary viscosity, and Pro PAC-LV is ideal for controlling fluid loss without having to increase viscosity.
