Turkish Starch for drilling

Starch, a natural polymer extracted from diverse plant sources like corn, wheat, and potatoes, holds immense significance in the realm of drilling operations within the oil and gas industry. Its unique properties render it an invaluable additive to drilling fluids.

Different types of Turkey Starch

In the industrial landscape, various modified starches, including HT, LT, HV, and LV Turkey starch, serve distinct purposes across different sectors like food, pharmaceuticals, and oil and gas.

HV Starch (High Viscosity Starch): Engineered to possess a higher molecular weight and increased viscosity compared to regular starch, HV Turkey starch serves as a versatile thickener, stabilizer, and binder in food and pharmaceutical applications.

HT Starch (High-Temperature Starch): Tailored to endure high temperatures, HT starch finds extensive use in industries such as paper manufacturing, textiles, and oil and gas. It acts as a thickener, binder, and fluid loss control agent in drilling fluids.

LV Starch (Low Viscosity Starch): Modified to exhibit lower viscosity than standard starch, LV Turkey starch serves as a coating agent, binder, and emulsifier in food and pharmaceutical sectors.

LT Starch (Low-Temperature Starch): Designed to withstand low temperatures, LT starch finds applications in paper manufacturing, textiles, and oil and gas industries, functioning as a thickener, binder, and fluid loss control agent in drilling fluids.

The incorporation of starch-based drilling fluids plays a pivotal role in regulating viscosity and controlling fluid loss during operations. By enhancing viscosity, starch facilitates the suspension of cuttings and prevents settling at the well bottom. Moreover, it aids in reducing fluid loss by forming a thin, impermeable filter cake on the wellbore walls.

Benefit of using Turkey starch

Noteworthy benefits of starch drilling fluids include their biodegradability, cost-effectiveness, non-toxic nature, and stability even in high-temperature drilling environments. These attributes make starch a preferred choice in the oil and gas industry, contributing to operational efficiency and environmental sustainability.

However, it’s crucial to acknowledge that the performance of starch-based drilling fluids may vary based on factors such as starch source and wellbore conditions. Therefore, employing high-quality starch-based drilling fluids and conducting comprehensive testing are imperative for ensuring optimal performance.

Beyond the oil and gas industry, Turkey drilling starch finds diverse applications across various sectors, including food, gas, and oil drilling. Its lubricating properties play a vital role in mitigating heating in pipes and reducing filtration throughout various processes.

Drilling Starch Usages

starch in drilling fluid viscosity high temperature and low temperature HT LV LT HV

The utilization of drilling starch in well lubricants is a well-established practice. However, it’s widely recognized that conventional starches have a tendency to degrade at elevated temperatures over prolonged periods. Specifically, conventional starches tend to break down or degrade at temperatures of 225°F or higher when exposed to such conditions for more than four hours. These high temperatures are often encountered in deeper wells, leading to the breakdown of conventional starches and subsequently increasing the consumption of standard types required in the drilling mud.

Important Parameters in Starch Drilling Analysis and Data Sheet

1. Viscosity: Viscosity plays a crucial role in determining the starch’s ability to suspend cuttings and maintain wellbore stability. Viscosity testing is typically conducted using a viscometer, such as a Brookfield viscometer, with results reported in centipoise (cP).

2. Particle Size: The particle size of starch can significantly impact its performance as a drilling fluid additive. Particle size analysis is commonly done using a laser diffraction particle size analyzer, with results reported in microns.

3. Fluid Loss: Fluid loss is a critical parameter that influences the drilling fluid’s ability to maintain wellbore stability and prevent formation damage. Fluid loss testing is typically carried out using a filter press, with results reported in milliliters.

4. Solubility: Solubility is vital in determining the starch’s ability to dissolve in water and form a stable solution. Solubility testing is usually conducted using a hot plate, with results reported as a percentage.

5. Purity: Purity testing is essential to ensure that the starch is free from impurities or contaminants that could affect its performance. This involves analyzing the starch for heavy metals, ash content, and other impurities.
