Lubricant Additives

Lubricant additives are purposed for decreasing friction coefficient of string against wellbore walls, decreasing torque and facilitating movement of drilling tools.

BL

Lubricant additive for drilling fluids BL is designed for processing fresh and salt muds while drilling vertical and directional sections of oil and gas wells. BL additive effectively reduces friction coefficient, considerably lowers risk of differential pressure sticking, torques during drill string rotation, makes drilling tool reciprocation easier, enhances service life of drill bits and provides increase in ROP.

BL additive does not cause foaming and besides of friction reducing also improves parameters of main technological properties of drilling fluids: structural and rheological, filtration, quality and durability of filter cake (provides friction coefficient reducing), produces an inhibiting action on argillaceous and clay-containing rocks. BL additive is easily dispersed in cold water, unproblematic in recycling, can be used in any drilling conditions and compatible with all chemical agents. Recommended for water based muds as 0.3–2% additive. It is added directly to mud. The volume of processing depends on formation types being drilled, ROP and mud cleaning system performance effectiveness.

Engineering recommendations

During mud processing with BL additive it is recommended to add reagent to the container with mixers or through the mud hopper for effective dispersing of reagent and its homogeneous distribution throughout the mud volume.

Toxicity and handling

It should be handled in accordance with general requirements of transportation, storage and use of industrial chemical agents. It is recommended to use personal protective equipment (glasses, gloves) and observe personal hygiene rules.

Package and storage

BL additive is supplied in metal barrels of 200 liters. It is recommended to keep it is cold dry place. Preserves its properties when frozen and after subsequent thawing.

BLSALT

Lubricating additive for salt water based muds and salt solutions for well completions. Represents the lubricating additive specially designed for reducing frictional forces during rotational and translational motions of drilling tool with use of drilling fluids with high content of mono- and bivalent metal salts, and also for drilling wells with complex profile and increased depth. This additive is subjected to quick biodegradation and non toxic. It also prevents balling, increases ROP and reduces risk of differential pressure sticking. It is quickly dispersed in any mud without solid phase.

Physicochemical properties

Lubricating additive for drilling fluids BL SALT represents oleaginous fluid from light yellow to yellowish brown color consisting of mixture of surface-active materials and additives produced on the basis of fatty acid esters of seed oil.

Engineering recommendations

Recommended and enough concentration of BL SALT additive for fresh and low-mineralized drilling mud is 5 kg/m3. For drilling fluids with high content of sodium, potassium and calcium salts, for salt saturated mud with high content of solid phase, calcium carbonate and barite recommended concentration is 10–20 kg/m3.

During processing muds with BL SALT additive it is recommended to add reagent to the container with mixers or through the mud hopper for effective dispersing of reagent and its homogeneous distribution throughout the mud volume.

Toxicity and handling

It should be handled in accordance with general requirements of transportation, storage and use of industrial chemical agents. It is recommended to use personal protective equipment (glasses, gloves) and observe personal hygiene rules.

BL SALT additive is supplied in metal barrels of 200 liters. It is recommended to keep it is cold dry place. Preserves its properties when frozen and after subsequent thawing.

BL-ECO

Lubricant additive for drilling fluids BL-ECO is designed for processing fresh and salt muds while drilling vertical and directional sections of oil and gas wells in offshore and onshore drilling. Additive is fully biodegradable and safe for the environment. BL-ECO additive effectively reduces friction coefficient, considerably lowers risk of differential pressure sticking, torques during drill string rotation, makes drilling tool reciprocation easier, enhances service life of drill bits and provides increase in ROP.

BL-ECO additive additive does not cause foaming and besides of friction reducing also improves parameters of main technological properties of drilling fluids: structural and rheological, filtration, quality and durability of filter cake (provides friction coefficient reducing), produces an inhibiting action on argillaceous and clay-containing rocks. BL-ECO additive is easily dispersed in cold water, unproblematic in recycling, can be used in any drilling conditions and compatible with all chemical agents.
