Modified starch makes the access to oil and gas deposits easy! Drilling starch is a chemically modified variant of starch derived from Maize, Potato and Tapioca that plays a crucial cameo in the complex and challenging process of oil and gas drilling. It helps by controlling the viscosity and fluid properties of the mixture of fluids, solids and chemicals, combinedly called the ‘mud’; used for perforating, lubricating and helping move the broken rock out of the way while drilling.
The starch molecules absorb water and then work like a thick gel that sticks to the walls of the hole being drilled. This gel seals the walls, preventing the precious drilling fluid from leaking into the surrounding rocks. Think of it as a plug in a leaky faucet to stop the water from dripping out. This helps keep the drilling process efficient and prevents the loss of valuable drilling fluid.
Additionally, Drilling starch can also enhance the filter cake formation on the borehole walls, further reducing fluid loss by creating a more robust barrier against fluid migration.
As hydrocarbon exploration is becoming more challenging especially during drilling in ultradeep water and high temperature and high pressure formations, conventional drilling muds fail to be effective as the high temperature and pressure alters the rheological properties of the drilling fluid.
Bluecraft Agro offers an economic yet highly effective solution to this challenging and complex procedure. We produce three impressive starches that simplify the task of drilling oil and gas, namely, High temperature drilling starch (HTDS), Low temperature drilling starch (DS) and DRILFLO 1009TM Carboxymethyl Starch (CMS)
HTDS, is a modified starch based filtration control agent that meets all high temperature drilling requirements. Bluecraft’s HTDS will reduce filtrate in freshwater as well as saturated salt environment whilst not increasing the fluid viscosity. Our uniquely engineered modified starch ensures seamless functionality without compromising fluid viscosity, making it a reliable choice for applications in both Drilling Fluid and reservoir settings.

Another feather in Bluecraft’s cap is the Low Temperature Drilling starch (DS). It proudly meets the API specification 13A. Our drilling Starch (DS) is proven to regulate filtration rates, bolstering bore-hole stability and handling drill cuttings in diverse water-based drilling fluid systems. Its adaptability to various drilling conditions and non-damaging characteristics position it as a dependable option for streamlining drilling operations. Formulated to diminish mud filtrate without substantial viscosity increments, DS guarantees optimal drilling performance by efficiently managing fluid properties.

Bluecraft also boasts of producing Drilflo1009TM, which is a Carboxymethyl starch-based filtration control agent that meets drilling specification. It like our previous variants is also used as an additive to control fluid loss in most water-based fluid system. Drilflo1009 is functional in simulated well site water as well as saturated salt environment and does not increase fluid viscosity. Drilflo1009 is non-damaging and can be used in both drilling fluid and reservoir drill-in fluid application.
