  • Can modified starch be used as drilling fluid additives?
  • The current state of the art with respect to applications of modified starch as drilling fluid (DF) additives and the main modification methods to produce them are reviewed in detail.
  • 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.
  • Do modified starch products have high-temperature tolerance?
  • However, certain modified forms of starch do display high-temperature tolerance that increases their attractiveness for a wider range of applications. In particular, modified-starch products are becoming more widely used in drilling fluids (DF) and certain enhanced oil recovery (EOR) techniques.
  • Is modified starch suitable for drilling deep wellbores?
  • For example, after treatment of modified starch with copper sulphate and antioxidants ( Soto et al., 2020 ), although the heat resistance can be improved, it cannot exceed 130 °C and is not suitable for DF involved in drilling deep wellbores ( Soto et al., 2020 ).
