HIBTEC^® is a standard high-performance water-based, clay free drilling fluid system. In more basic terms, it is classified as a non-dispersed, ultra-inhibitive system for environmentally sensitive areas on and offshore including highly reactive shales. It is designed to:

  - Provide superior shale inhibition and wellbore stability

  - Provide low accretion and bit balling tendency

  - Offer flexibility in density and base brine selection

  - Compete with NAF systems without a sacrifice in the drilling performance

  - Provide the environmental benefit of unrestricted cuttings discharge based on most worldwide water-based fluid environmental regulations

  - Applications in reservoirs containing reactive clays as return permeability studies demonstrate the HIBTEC^® system is non-damaging

HIBTEC^® system is non-toxic and biodegradable as same chemistries used in food and cosmetic products. You can use HIBTEC^® in virtually any offshore or onshore well anywhere in the world with no concern over its environmental acceptability.

HIBTEC^® has an inhibitive capability closely matching that of nonaqueous drilling fluids. Its quadruple-inhibition approach deters the most reactive shales and provides superb wellbore stability, preventing sloughing and swelling that can cause stuck pipe and washouts. 

The system encapsulates cuttings with a thin polymer coating that virtually eliminates shale dispersion, reducing the need for dilution and disposal of large fluid volumes. The HIBTEC^® system also coats the bit, BHA and drillpipe with an accretion-inhibitive coating that keeps the cutting structure clean and effective, resulting in less bit balling, superb hole cleaning and higher ROP.

HIBTEC^® system is typically used for more challenging drilling requirements, including extended reach wells where ECD is an issue, deepwater wells, gumbo and dispersive clays, highly-reactive shales, reservoirs and slim holes.

HIBTEC^® has good, stable and easy-to-maintain properties of density range within 18.5ppg (2.2sg) and temperature tolerance up to 300°F (149°C).

¬  1ppb = 2.857kg/m³, 1ppb = 1g/350ml

¬   Add microbiocide as required to reduce bacteria through the control of sulphate

¬    Temperature stability can be increased with the addition of oxygen scavengers

¬   Add defoamer as required. This may be essential in salt systems

¬   Add sized ground marble as required

¬    Pilot testing should be performed to determine the exact amount of each product used in a particular formulation under elevated temperatures

To ensure that the fluid formulation truly meets your required specifications, SHARK's expert will work with you to pilot test the fluid before fully deploying it as part of your drilling program. 

To achieve a customized drilling fluids solution and optimized shale inhibition, a suite of all items in water-based mud testing have to be conducted. Besides, special designed laboratory tests are also critical to the successful application of HIBTEC^® system in the field.
