For decades, non-aqueous drilling fluids (NADF's) have been the fluid of choice to drill challenging wells. This is because they possesses high robustness, high rate of penetration (ROP) and high thermal stability. However, there is a growing interes

Two hydrophobic vinyl saccharide monomers based on D-glucose and D-fructose were polymerized by employing the reversible addition-fragmentation transfer (RAFT) miniemulsion polymerization technique to prepare well-designed glycopolymers. Three dithio

Oil-based drilling fluids using a micronized ilmenite (5 µm) as weighting materials are proved to be suitable for HP/HT drilling operations with good rheological properties, low sag tendency, and low filtration volumes, even after heating at 400°F

Hydraulic fracturing is used extensively to develop oil and gas wells in both high and low-permeability formations. Biopolymer-based fluids, including guar or guar derivatives, constitute the majority of polymers in fracturing fluids. These polymers

Sugar latexes based on saccharid derivatives, such as 3-MDG, 1- or 3-MDF and ITDF, have been synthesized in batch and semi-continuous emulsion polymerization. The polymerizations were carried out at 60 or 70°C, initiated by potassium peroxodisulfate

Ilmenite (FeTiO3) was first introduced as a weight material in the North Sea area in the early 1980's. The quality of ilmenite suitable for drilling fluids was continuously improved to meet the drilling criteria. Ilmenite as a weight material offers
