Starch in drilling is a common practice in the oil and gas industry due to its
effectiveness and cost-efficiency. However, it is important to note that the
performance of starch-based drilling fluids can vary depending on the source of
starch and the conditions of the wellbore. As such, it is essential to use
high-quality starch-based drilling fluids and to conduct proper testing to
ensure optimal performance.
Advantages of using Starch in Oil Drilling:
- It provides wellbore stability through filtration control
- It helpsto keep the drill bit cool and lubricate, by removing the rock fragments or
drill cuttings from the drilling area and transport them to the surface.
- It isused to stabilize rheology and to reduce the filter cake permeability
- Effectivein a wide range of make -up water, including high hardness and high salinity,
