  • Can modified starch derivatives be used to control filtrate in drilling fluids?
  • This study investigates the potential of using starch derivatives modified with vinyl esters from fatty acids, as additives to control filtrate in invert-emulsion (W/O) drilling fluids. There are no reports of the use of modified starches as additives to control filtrate in non-aqueous systems.
  • Are starch derivatives used in oil & gas drilling?
  • Starch derivatives are infrequently employed as filtration reducers during the drilling of the top-hole sections of oil and gas wells (i.e., surface/intermediate casing intervals). When they are utilized, it is usually with salt-water-based DF or under high salinity conditions.
  • Is modified starch suitable for drilling?
  • The review considers the processes and economic and environmental issues involved in DF applications of modified starch. Drilling fluid (DF) is an essential requirement for the safe and efficient drilling of all types of boreholes (Davoodi et al., 2022).
  • Which starch is used as DF additive?
  • The most widely used modified starches as DF additives are pre-gelatinized precipitates, carboxymethyl starch, hydroxypropyl starch, sulphonated starch, graft copolymerization products, and phosphate oxide starch. Of the modified starches mentioned, carboxymethyl starch displays the highest temperature resistance.
  • Can modified starch be used as a DF treatment agent?
  • When used as a DF treatment agent, modified starch generally has good performance in reducing filtration loss, increasing viscosity, and stabilizing wellbores during drilling (Davoodi et al., 2022; Guan et al., 2021).
  • Can modified starches be used as filtrate control additives?
  • Nevertheless, there are no reports of the use of modified starches as filtrate control additives in oil-based drilling fluids. The characteristics of the geological formation and the well geometry determine the type of fluid to be used in a drilling operation .
