DRILLING FLUIDS WATER-BASED SYSTEMS

Our water-based drilling fluid systems deliver cost-effective performance with minimal environmental impact. We are a pioneer in developing high-performance systems specially formulated for a myriad of applications even in environmentally sensitive drilling areas.

HYDRO-FOIL

is the original KCI / PHPA low solids, non-dispersed fluid system that is primarily used to drill moderately reactive shales. FEATURES AND BENEFITS

The two primary shale inhibitors in the system are potassium ions for cation exchange with the clays, to reduce hydration and swelling, and partially hydrolysed polyacrylamide to encapsulate drilled cuttings for more effective solids removal efficiency on surface. In recent times environmental restrictions onshore have restricted the discharge of chloride-based fluids, which has resulted in the use of alternative aqueous-based fluids, including:

TYPICAL FORMULATIONS AND PROPERTIES OF A CONFI-DRILL SYSTEM WITH A LINEAR PARAFFIN PRODUCT

The CONFI-DRILL invert emulsion system consists of three phases: non-aqueous, brine and solids phase. The most important parts of the system, however, are the emulsifying chemicals designed to create and maintain the invert emulsion. The system can be formulated using various base fluids, including Low Toxicity Mineral Oil (LTMO), Linear Paraffin (LP), Linear Alpha Olefin (LAO) and Internal Olefin (IO).

This system has excellent rheological and filtration characteristics which are easily modified to meet changing temperature and pressure conditions. TYPICAL WELL COST COMPARISON USING CONFI-DRILL VS. INHIBITIVE WBM $

CONFI-DRILL is an invert emulsion system, the composition of which can be tailored to meet environmental regulations and performance criteria. CONFI-DRILL is a very stable invert emulsion synthetic drilling fluid, selected because of its great flexibility in meeting changing drilling conditions.

TYPICAL FORMULATION AND PROPERTIES OF A CONFI-DENSE SYSTEM Increasing demand for drilling deviated HTHP wells has resulted in the development of an HTHP non-aqueous drilling fluid with unique suspension properties to avoid commonly observed density differentiations under extreme conditions. The CONFI-DENSE system is stable to temperatures above 400 °F and exhibits minimal density differentiation under dynamic and static conditions. The system can be weighted to densities above 18.5 lb/gal (SG 2.20) using API barite, or alternative weight materials including HyPR-BAR (fine grind barite), NANO-BAR a proprietary, non sag, alternative weight material with a minimum SG of 4.35, Haematite or Micromax.

The potential for barite sag can be a major concern issue with non-aqueous fluids particularly in directional wells with inclinations > 30° and mud weights > 12.0 lb/gal, a potential which, if not addressed, can lead to critical well control issues especially in HTHP wells. This potential is exacerbated at the highest inclinations, 60° – 75° in long tangent ERD wells and where thinning of the fluid occurs due to high temperatures and pressures.

CONFI-DENSE is typically maintained with an O/W range of 85/15 - 90/10 and is specifically designed for use with commonly available synthetic base fluids. Static barite sag tests with CONFI-DENSE show excellent results that fall well within the sag factor criteria specified by major oil companies. CONFI-DENSE also exhibits very low amounts of supernatant oil (syneresis) in samples aged both static and dynamically. Field tests demonstrate that the laboratory formulation properties further improve during drilling conditions as drill solids are incorporated into the system combined with the shear from the drilling operation.

A simple sag factor measurement has been developed to conveniently express the degree of settling, with CONFIDENSE results being well within the acceptable range of 0.50 – 0.53. Calculated as follows: Sag factor =

p bot (p bot + p top)

Where: p top = Maximum density (top), g/cc p bot = Maximum density (bottom), g/cc Recent developments include the use of alternative different particle size weighting materials such as fine grind barite, HyPR-BAR, NANO-BAR, an alternative 4.35 SG weight material, fine grind Haematite and Micromax, shown on previous page, to deliver reduced sag potential and ECD values. CONFI-DENSE is field proven in areas including Malaysia and Thailand giving our customers exceptional HTHP drilling performance.

AFTER HOT ROLL @ 200 ºF for 16 hours

Conventional invert drilling fluids address cold water issues by lowering the viscosity at surface temperature in order to achieve a decreased overall rheological profile to counter the increased rheological profile under cold temperature conditions, i.e. at the seafloor. This approach will give lower ECD when encountering cold temperatures, however as a consequence, what often results is poor hole cleaning, barite sag and other downhole drilling problems related to a greatly reduced low rheological profile under bottom hole static and circulating temperatures. Conversely, adjusting the rheology upwards to compensate for higher BHT will lead to high ECD and excessive gel strengths producing pressure spikes that can break down the formation and promote lost circulation.

Drilling fluids formulated with the CONFI-DEEP technology are designed to minimise the downhole losses normally associated with deepwater drilling. CONFI-DEEP achieves this with the use of an enhanced rheological modifier thus minimising the use of organophilic clay in the formulation. The result is a fluid system which has exceptional low end rheological characteristics over a wide temperature range, thereby promoting hole cleaning, whilst minimising ECD, surge and swab pressures.
