Oil & Gas - Betafib

MCF as viscosifier, is a 100% natural biopolymer that has a unique stability at elevated levels of temperature AND alkalinity. The presence of electrolytes has no impact on its stability.  That makes it the product of choice in drilling, cementing, fracturing applications and suppletion fluids.

Introduction
Viscosifi cati on is one of the key operati ng factors in the oil & gas industry. In today’s world, making the most of every reservoir becomes increasingly relevant. As a result, service companies are facing more challenging conditions. Increased levels of temperature, alkalinity and pressure in complex matrices demand new chemistries and innovative technological soluti ons. At the same time the requirements
for environmentally friendly production and drilling fluid additives is increasing due to the growing awareness of sustainability in both society and industry. Biobased viscosifiers offer a potential solution in this challenging environment.







Benefits
The use of Betaf b delivers the following benefits:
• Excellent particle carrying properties under low and no shear conditions
• Fast enzymatic breakdown
• Low dosages and synergies with clay
• One viscosifier covers a broad spectrum of fluids
    Temperature stable up to 356 °F
    Unaffected by pH from 1 – 14
    Stable under presence of electrolytes, also for heavy brines
• Ease of handling because of down hole activation whilst
remaining pumpable due to shear thinning character



Applications
• Drilling muds
• Fracturing fluids
