OIL DRILLING STARCH
 [CODE NO. 3349 ]

Starches are an environment-friendly drilling mud additive for water-based fluids.A drilling- mud additive used to control fluid loss in water muds ranging from freshwater to saturated- salt to high-pH lime muds. Starches have thermal stability. They are subject to bacterial attack unless protected by high salinity or bactericide. Drilling-grade natural starch has API/ISO specifications for quality. The use of starch typically causes a minimal increase in viscosity while effectively controlling fluid loss. Modified starch polymers provide improved high temperature fluid loss performance when incorporated into well drilling fluids.
Starches are an environment-friendly drilling mud additive for water-based fluids. These starches are used as viscosifiers in oil well drilling and are exported 100% to the Middle East. These are also one of the key ingredients of a mud chemical system.

A drilling-mud additive used to control fluid loss in water muds ranging from freshwater to saturated-salt to high-pH lime muds. Starches have thermal stability to about 250°F [121°C]. They are subject to bacterial attack unless protected by high salinity or bactericide. Drilling-grade natural starch has API/ISO specifications for quality. Starches are carbohydrates of a general formula (C6H10O5)n and are derived from corn, wheat, oats, rice, potatoes, yucca and similar plants and vegetables. They consist of about 27% linear polymer (amylose) and about 73% branched polymer (amylopectin). The two polymers are intertwined within starch granules. Granules are insoluble in cold water, but soaking in hot water or under steam pressure ruptures their covering and the polymers hydrate into a colloidal suspension. This product is a pregelatinized starch and has been used in muds for many years. Amylose and amylopectin are nonionic polymers that do not interact with electrolytes. Derivatized starches, such as hydroxypropyl and carboxymethyl starches, are used in drill-in fluids, completion fluids and various brine systems as well as in drilling-mud systems. The use of starch typically causes a minimal increase in viscosity while effectively controlling fluid loss.

It is used for reducing fluid loss in a variety of water based drilling fluids and has beneficial secondary effects on mud rheology. In drilling wells, a liquid (mud) is pumped into the hole to clean and cool the drill bit and to flush to the surface the drill bit cuttings and suspending the drill cuttings while drilling is paused. The most important physical characteristics of the drilling fluid is the viscosity and the water holding/retaining characteristics.
 
Starch is traditionally supplied as cold water soluble - either made by a semi moist/dry thermo-mechanical gelatinisation on screw extruders or by suspension reactions and subsequent drying on drum dryers. Wet reactions carried out in starch suspensions are easy to control and the resulting precisely engineered starches are of high, uniform quality with wider applications. Potato starch retain fluids better than other starches due to the large size of its molecules.
