S3 FLUIDS for HORIZONTAL DIRECTIONAL DRILLING Works

A Perfect Drilling Fluid Formulation plays a major role in the successful execution of any Horizontal Drilling Operation.

It is imperative to establish an appropriate Mud program before commencement of drilling. The Mud Program shall take into consideration the type of Ground conditions and the equipment setup.

During the drilling operation itself, the Mud Properties should be constantly monitored.

Modifications to the mix design & drilling fluid properties to be carried out as needed to optimize performance or counter any unforeseen situations such as lost circulation, severe torque and drag etc.

Functions of a Drilling Fluid for HDD Works

Transporting drill cuttings to the surface by suspending and carrying them in the fluid stream flowing in the annulus between the bore wall and the drill pipe/product.
Cleaning off build-up on drill bits or reamer cutters by directing fluid streams at the cutters
Cooling the downhole tools and electronic equipment.
Lubricating to reduce the friction between the drill pipe/product and the bore wall.
Stabilizing the bore, especially in loose or soft soils by building a low permeability filter cake, and exerting a positive hydrostatic pressure against the bore wall. The filter cake along with positive hydrostatic pressure reduces collapse of the bore and prevents formation fluids (i.e. groundwater) from flowing into the bore or drilling fluids from exiting the bore into the formation (loss of circulation)
Providing hydraulic power to downhole mud motors.

S3 FLUIDS for MICRO TUNNELLING – PIPEJACKING Works

To ensure the success of a MicroTunnelling –Pipejacking Operation, a carefully selected appropriate Drilling Fluid Formulation is necessary that should be able to overcome the frictional resistance induced during the jacking of the pipes in the ground.

When excavating through unstable formations, a suitable mud must be formulated to achieve an efficient face support and help the excavation, as well as easing the removal of excavated cuttings.

Functions of a Lubricating Fluid in Microtunnelling – PipeJacking Operation:

The Lubricating Fluid helps to reduce the jacking force by reducing the Frictional forces caused due to the contact between the soil and the pipe.
The Fluid also assists in the stabilisation process of the oversize cut in unstable soil.
The Rheological Properties of a Lubrication Slurry need to be constantly monitored and adjusted whenever necessary in different Ground Conditions, eg. to limit the hydration of water sensitive formations eg.sticky, swelling clay etc.

S3 FLUIDS for SPECIAL FOUNDATION Works

The Selection of an optimal Fluid Formulation in Special Foundation works depends on factors such as Type of Excavation: Bored Piles, D-Walls / Cut-Off Walls etc. in addition to the Ground Conditions & the Equipment being used for the purpose.

The Functions of the Drilling Fluid in a Deep Foundation Operation:

Ensure the stability of the excavation during the drilling upto the Concreting Stage. The formation of an impermeable cake in case of a Bentonite Fluids permits the application of the required hydrostatic pressure to counterbalance the Ground stress arising from earth pressure and the groundwater.
The Fluid maintains the cohesion of the soil in the vicinity of the open trench thanks to its yield point that limits the penetration of the drilling mud into the formation.
The drilling fluid also helps suspend excavated Solids, allows the transport and the removal of the cuttings.
