Frequently Asked Questions
Do you provide mud training?
Yes. We offer a unique three-step approach that includes fluids planning and consulting assistance, fluid training and education for frontline staff, as well as technical assistance and service. Learn more about our Drilling Fluid Training, Support Services, and Consultation via this link.
Is drilling mud toxic?
Drilling mud itself is not inherently toxic, but its safety depends on the additives used. Many common water-based drilling fluid components are considered low-toxicity; however, certain chemicals, polymers, or contaminants introduced during drilling can make the mud irritating or mildly hazardous if handled improperly. To ensure safety, proper PPE should always be worn when mixing, handling, or disposing of drilling fluids and additives.
What types of drilling products does Di-Corp offer?
Di-Corp manufactures, distributes, and supplies a comprehensive selection of drilling solutions, including bentonites, cements and grouts, flocculants and coagulants, general chemicals, greases and lubricants, lost circulation materials, polymers, thinners and dispersants, weighting materials, and waste treatment and solidifying agents.
What factors should I consider when choosing directional drilling fluids?
Selecting the right directional drilling fluids depends on soil type, bore length, flow requirements, and expected downhole challenges. Properties such as viscosity, gel strength, fluid loss control, and suspension capability all play a role in how well a fluid performs in different formations. At Di-Corp, we’ll help you determine the directional drilling fluids your operations require.
How do I know if my HDD drilling mud system is performing correctly?
A well-performing HDD drilling mud system will maintain steady pump pressure, carry cuttings efficiently, prevent excessive fluid loss, and support steering accuracy. Regular flow checks, density readings, and rheology tests help ensure fluid quality stays within target ranges.
