ePROQDRIL is diesel based drilling fluid system and helps lower well construction costs. Relying on emulsion and polymer

technology for rheology, this new drilling fluid system, with 3 (primary & secondary emulsifier and wetting) in 1 emulsifier, delivers the

durable and temperature stable invert emulsion performance, without the associated elevated gel strengths.

How it works

Conventional oil based fluids require excessive pressure to break the gel structure resulting in significant surge on the wellbore,

resulting in increased losses. Lower oil content requirement and the 3 in 1 emulsifier of the ePROQDRIL system help operators save

on actual diesel costs and the transportation costs to the job location. With the decrease in deliveries to location, there are fewer

opportunities of HSE incidents, resulting in increased safety performance.

ePROQDRIL requires less pressure to initial circulation resulting in significantly lower downhole losses while drilling, running casing

and cementing. The system's well performance at 6 RPM dial reading and the gel structure allows for superior cuttings transportation,

dramatically improving hole cleaning.

Features Benefits

•Primary & secondary emulsifier and wetting function in 1 additive •Simplified logistics

•Lower rheological properties result in lower pump •Optimized drilling efficiency

•Lower HPHT fluid loss excellence solids, temperature,

contamination tolerance

•Higher water ratio, especially in the lower drilling fluids densities

•Lower pump pressures


2.2 eTALENDRIL / eTALENCLEAN (Engineered to meet any drilling fluid requirement)

The eTALENDRIL and eTALENCLEAN systems are oil based fluids, formulated with TALEN COAT & TALEN WET or TALEN EMUL &

TALEM COAT emulsification packages, and the two fluid systems are engineered to meet most of the drilling fluid requirement.

The difference between the two systems is that the eTALENCLEAN system uses a highly refined mineral oil as the continuous

external phase, while the eTALENDRIL system is formulated with diesel oil.

Applications

Both systems deliver very good thermal stability for drilling deep, hot holes. eTALENCLEAN and eTALENDRIL systems can minimize

the damage to produce formations through the prevention of water intrusion, thereby eliminating clay swelling, which can cause

reduced permeability of the pay zone. They also provide increased rates of penetration and ability to drill thick, water sensitive shale

sections with relative ease, thus providing for gauge hole drilling.

2.3 eSHALDRIL Excellent Shale Gas Drilling Fluid

With its flat rheology, this unique eSHALDRIL system maintains consistent fluid properties. This fluid system are specially engineered

to work synergistically to maintain stability throughout the drilling and evaluation phases. With deep research on the filtration

mechanism of the shale gas and proper plugging agents plus super shale inhibitor, this system controls filtration without increasing

overall viscosity and has a higher tolerance for drilling solids which can cause progressive gel strength.

Flexible nano-emulsion with namo particles, perform like "wall-pasting" and change

the particle size distribution of the mud.

Softenable modified asphalt resin, with wide particle size distribution, and become

softened when downhole temperature rises. Finally forming a sealing membrane.

Special treated natural network fibers supplemented with micro-expansion polymer

and elastic micro-particles. When entering the microcrack, by bridging, expansion and

forming a high strength sealing membrane to plug the filtration channel.

Applications

With stable borehole and variable choice of plugging agent, eSHALDRIL is a preferred system for shale gas drilling. In addition, low

fracture gradients and narrow ECD windows, which are often encounter in deepwater operations, greatly increase the risk of lost

circulation, which can drastically increase the cost of the operation.

Features Benefits

•Lower fluid losses and reduced fluid and well construction costs •Flat rheological profile over a wide temperature range

•Improved ECD management •Reduced sag potential

•Minimized formation fractures •Less dilution / maintenance

•Optimized drilling efficiency •Improved hole cleaning, cuttings suspension

•Significantly reduced whole drilling fluids losses •Reduced pressure spikes
