Which polymer is used as Viscosifier in drilling mud?
Which polymer is used as Viscosifier in drilling mud?
Haizan DHV is high viscosity dispersible xanthan gum biopolymer that gives high viscosity build at low shear rates. It can be utilized as a viscosifier in oilfield drilling, workover and completion fluids. It is a high molecular weight polysaccharide produced by fermentation of carbohydrate with Xanthomonas Campestris.
What does Viscosifier mean?
viscosifier (plural viscosifiers) A chemical that viscosifies.
What is a weighting agent?
Weighting agents are used to control formation pressures, prevent formation caving, and facilitate the pulling of dry pipe.
What are drilling fluid additives?
Drilling fluid additives are specialty products that serve a specific need. CLAY-DRILL polymer-based HDD fluid is designed to provide borehole stabilization, counteract the sticking tendencies of clay, and maximize clay/shale inhibition without the need for additional additives.
What is water based mud?
Water-based mud is a type of drilling mud consisting mainly of water, which has additives to modify it and make it more effective. Water-based mud is a drilling fluid composed of water and bentonite and heavy minerals which are also added for weight.
Which are the rheological properties?
Rheology properties are manifestation of the rate and nature of the deformation that occurs when a material is stressed. These parameters can be used to predict how the fluid will behave in a process and in determining the energy requirement for transporting the fluid from one point to another in processing plant.
Is Sucrose a Viscosifier?
Sucrose was used as a viscosifier, however we note that this additive leads to finer emulsions (droplet size is reduced with an increase of the sucrose content) (Fig. 3(b)).
What are emulsifying agents?
An emulsifying agent (emulsifier) is a surface-active ingredient which adsorbs at the newly formed oil–water interface during emulsion preparation, and it protects the newly formed droplets against immediate recoalescence.
What is beverage emulsion?
Beverage emulsions are concentrated emulsified systems designed to be further diluted and/or incorporated in beverages and drinks as carriers of water insoluble ingredients.
What are the types of drilling fluid?
There are three broad categories of drilling fluids: • Pneumatic fluids, which use compressed air or gas, foam and aerated muds; • WBMs, which use water or brine as the base fluids; and • NAFs, which use oil or other non-aqueous base fluids called OBMs or SBMs.
Why is barite used as drilling mud?
Barite plays an essential role as a weighting material in drilling muds used in oil and gas drilling, primarily to prevent the explosive release of gas and oil during drilling.
Which type of clay is used as a drilling mud?
bentonite clay
Water-based drilling mud most commonly consists of bentonite clay (gel) with additives such as barium sulphate (barite), calcium carbonate (chalk) or hematite.
