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.
