Drilling fluid pH is an important factor in drilling and production operations. If the acidic, this will cause metallic parts such as string casings to corrode. Also, much more additives be needed achieve right rheological properties. In work, suitability of agro waste oil palm fruit fibre, ripe plantain peels unripe control agents was studied. The materials were gotten from local sources subje...

This chapter evaluates and compares the indoor performance of different concentrations non gelatinized starch in drilling fluid, modified at 80°C, then aged high temperature. Taking plastic viscosity (PV) filtration loss (FL) as main evaluation indexes, a formula with better was selected additive used follow-up study. At same time, inhibition water-based fluid investigated.

Abstract Because of the rock carrying property drilling fluid, it is usually necessary to add bentonite and polymer into fluid improve viscosity fluid. However, will seriously affect rheological property, sand speed, degassing effect, etc. Therefore, develop a new environment-friendly low cutting agent for In this paper, konjac gum was modified by metal complexation. Some were studied. The effe...

Based on its good water solubility, temperature resistance and environmental protection, oligosaccharides are widely used in food beverage, baking medical care. In view of the poor lubrication performance drilling fluid ultradeep wells, long horizontal wells highly deviated problems protection faced by lubricants, application is limited. Therefore, order to reduce limitations improve applicatio...
