High-Performance Chemicals for Drilling
For most of the oil companies, the costs for drilling become higher and higher with more and more difficult well conditions. A series of suitable chemical additives are essential for the completion a successful and economical well. L.E.A.D.'s R&D has focused on the drilling chemicals for years, with our lab's selection and on-field applications, L.E.A.D.'s drilling series has been verified with high performance and low cost in drilling process.
With consistent product quality and essential development, our
drilling solutions offer best impact on the fluid system.
Maximizing the efficiency and lower the total cost, not limited,
most of L.E.A.D.’s additives are certified as environmental
friendly, which are important against the environmental low.
L.E.A.D.’s drilling series include viscosifiers, HTHP fluid loss
agent, shale inhibitor, lubricants, foamers, defoamers, etc. With
our broad range of products, users could solve the most
challenging problems on the field, to maximise the total output
with lower input. With no stop improving the quality and
performance, we L.E.A.D. would like to help service companies
to obtain the best outcome with L.E.A.D.’s products.

Drilling Portfolio High-Performance Chemicals for Drilling and Completion Fluids
L.E.A.D. offer a broad range of specialty chemicals across the
drilling completion process. the focus is on high temperature
stable, high performance, salt tolerance, low dosage, low
damage, low toxic products for drilling and completion fluids.
Also, L.E.A.D.’s products works well in fluid loss and shale
inhibitors.
Clean up additives are also L.E.A.D.’s advantage compared with
other chemical companies, with low dosage, L.E.A.D. surfactant
could work fast and efficiently to clean up the waste matters from
the flow back fluid, providing a functional condition for the drilling
process.
High-Performance Chemicals for Drilling and Completion Fluids
Drilling fluids are used to transport the cuttings to the surface.
After preparation of the fluid, the drilling mud is pumped into
the drill string. Downhole, the drilling fluid leaves the drill bit
through nozzles, cooling and lubricating the bit. Then, the fluid
rises in the annulus, carrying the cuttings upwards. Above
surface the drilling fluid is processed, refined and reused for
as long as its technical properties can be maintained.
The drilling fluid has other important tasks including hydrostatic
protection of the wellbore against collapse and prevention of
formation fluid influx into the well. Additionally, through formation
of a filtercake at the borehole wall, the fluid has to minimize
the loss of water to the geological formation. If water loss is
uncontrolled, control of the well while drilling may be compromised
and subject to undue risk.
Drilling fluids are characterized by shear thinning flow behavior
and – at rest – by gel formation. This is of special importance
when the circulation of the fluid must be stopped, e.g., to add
further drill strings or to change the drill bit. In these situations
the drilling fluid, which was thin and easily pumpable,
has tothicken instantly to keep the drill cuttings in suspension.
How L.E.A.D. Oilfield Solutions could help with your drilling and completion mud
L.E.A.D. offers a broad range of specialty chemicals across the drilling completion process. the focus is on high
temperature stable, high performance, salt tolerance, low dosage, low damage, low toxic products for drilling and
completion fluids. Also, L.E.A.D.’s products works well in fluid loss and shale inhibitors.
L.E.A.D.’s Hole-Mers product range covers most of the additives widely used in drilling fluids. They function as viscosifiers,
shale inhibitors, lubricants, biocides, fluid loss control agent, etc.
Dris-K is a fluid loss control additive for water and salt water drilling mud. Dris-K is composed by several high performance
polymers with special functions. It could works well above 210 C/ 400 F.
Dris-Vis is a range of products used as viscosifiers for drilling muds. It is natural or synthetic high molecular polymers
which work well for the typical type of fluid systems. For the deep wells, L.E.A.D. offers customised viscosifiers witch could
tolerate the high temperature and high salt in downhole.
Sili-D is a type of silicone defamer designed for drilling muds, it could break the foam fast and equip with good foam
inhibition function.
L.E.A.D. drilling fluid additives are temperature-stable, high performance and high cost-effective products for a variety of drilling fluid systems.
