  • Stable up to 400°F (204°C)

Product introduction

UBDrill-261 is a kind of OBM thinner and then diluting them with a certain amount of white oil while using. During the drilling process, fine drill cuttings particles will disperse and accumulate in the drilling fluid. Excessive solid phase can rapidly lead to an increase in rheological parameters, including static and dynamic shear.

An increase in rheological parameters will reduce drilling speed and increase pump pressure until it exceeds the fracture pressure of the formation.

The addition of UBDrill-261 diluents to oil-based mud effectively solves the problem of increased rheological parameters caused by ultrafine drilling cuttings in the absence of efficient solid control equipment.

Frequently Asked Questions (FAQ)

What is UBDrill-261 and how does it work?
UBDrill-261 is an oil-based mud (OBM) thinner. It works by diluting with white oil during use to effectively control and reduce the rheological parameters (such as static and dynamic shear) caused by the accumulation of fine drill cuttings in the drilling fluid.
What are the primary applications of UBDrill-261?
UBDrill-261 functions primarily as a thinner to reduce drilling fluid viscosity. It is highly suitable for use in high-temperature and high-pressure (HTHP) wells.
What is the recommended dosage for UBDrill-261?
The recommended dosage for low-density systems is 0.1% to 0.25% (v/w), and for high-density systems, it is 0.5% to 1%. However, a pilot test is highly recommended to determine the optimal dosage for your specific drilling conditions.
What is the thermal stability limit of UBDrill-261?
UBDrill-261 exhibits excellent thermal stability, remaining stable at temperatures up to 400 °F, making it ideal for demanding downhole environments.
How should UBDrill-261 be packaged and stored?
It is packaged in 55-GAL drums. It should be stored in a dry, well-ventilated area with containers tightly closed. Keep the product away from heat, sparks, open flames, and incompatible materials. Follow standard safe warehousing procedures.
