74 • Offshore • September 1998

The development of drilling and comple-tion fluids beyond the basic liquidpumped downhole reflects much of thepetroleum industry’s growth. At onetime, drilling fluids were expected to do

little more than cool and lubricate the bit, trans-port cuttings, and control pressure. Completionfluids were of little consequence beyond pro-tecting the tubing string from corrosion.

By 1988, a handbook of drilling fluids, pub-lished by a still viable if differently named mudsupply company, listed ten drilling mud func-tions. Today, the role of completion fluids hasgrown with the complexity and creativity ofcompletion scenarios, driven by such innova-tions as high-angle wells, overbalanced perforat-ing, and gravel pack operations.

Drilling fluids research through theyears has revealed the negative effectsof using drilling or completion fluidsincompatible with producing formationchemistry. Proper fluid selection pro-tects the formation during the drilling,completion, and cleanup stages of thewell, while the wrong fluid chemistrycan inhibit production via excessiveskin damage or fluid invasion that candrastically reduce formation perme-ability at the near wellbore.

Wellbore stabilityBeyond pressure and formation

damage control and remediation, fluidselections now must consider wellborestability, shale and clay sensitivities,penetration rates, and countless othersubtle and not-so-subtle effects ofdownhole chemical reactions.

Drilling and completion fluids suppli-ers have become adept at targeting individualwell problems.

Special additives are made available for wellswhose geometry or lithology suggest the riskof stuck pipe problems. Additives exist to helprelease pipe differentially plastered to the sideof the wellbore. Fluids recipes are dictated byeverything from wellbore angle to degree offormation depletion.

Hydraulic fracture fluids have become ascience of their own as fracturing has grown toinclude huge volumes of proppant depositedfar from the wellbore to increase productionfrom low-permeability formations to relativelysmall fractures in high-permeability formationsfor sand control and near well bore, post-perforation cleaning.

A factor of the times has been added to the

world of fluids as preservation of the environ-ment becomes a more pronounced issue world-wide. The choice of base mud and additives bestsuited to the surrounding environment is criti-cal. Drilling through an underpressured zone inthe American west, for example, requires a fun-damentally different chemistry than might thesame set of circumstances in the NorwegianContinental Shelf.

Water, oil, syntheticsOne result of the environmental movement

on fluids chemistry has been fundamental. Atone time, all muds were water-based, oil-based,or a combination inverted emulsion. In re-sponse to environmental restrictions on over-board cuttings discharge when drilling with

oil-based muds, the substitutes, called synthetic,or pseudo-oil muds, were born.

These fluids responded to a need to use oilbase muds in the high risk world of high-angledrilling and to maintain the high penetrationrates associated with oil-based muds while com-plying with increasingly strict environmentalregulation. Where OBMs must be used in aclosed, zero-discharge system, cuttings fromsynthetic muds may be discharged overboard inmany areas (though in some areas where thepractice is allowed, it is under scrutiny - mostnotably the UK North Sea).

While synthetics are, by-volume, moreexpensive than water- or oil-based systems, theyare less costly than other muds when their useresults in fewer drilling days by virtue ofimproved penetration rates.

New drilling and completion technologiesdemand fluids responses. The proliferation dur-ing the 1990s of high-angle and horizontal wellshave spawned a unique set of responses to theneed for non-stick, non-invasive fluids asprospective producing formations must oftenremain exposed to drilling mud for extendedperiods of time.

In high-angle wells, the effective circulatingdensity of the mud must naturally rise with mea-sured depth while the fracture gradient of therock remains essentially the same, the chem-istry of invasion, and even lost circulation,becomes more challenging as reach sectionsgrow ever longer.

As the oil and gas industry expands itsdrilling and completion theaters, fluids must

evolve. The immediate challenges tothe fluid chemists are in deepwaterand in drilling through subsea salt. Indeepwater, particularly in the Gulf ofMexico, shallow, flowing aquifers arecausing considerable problems fordrillers attempting to set conductorpipe. One approach to the problemhas been to seek a polymer to act as awater shut off.

Drilling and casing through extendedsalt sections is fraught with danger. Saltis capable of near-fluid movement,impinging on the wellbore, and at thesame time, it can be washed out easily.

As the following fluids survey bearswitness, proper fluid selection is ascritical and complex a pre-drilling con-sideration as casing size, bits, or any ofthe myriad decisions involved in plan-ning a new well.

Fluids directoryThe 1998-1999 Environmental Drilling &

Completion Fluids Directory is a comprehen-sive listing of 56 of the industry’s top fluid manufacturers and their individual products.The directory is differentiated into 14 sectionsbased on the type of fluid.

Six new companies have been included inthis year’s directory: Hydro Chemicals that hastaken over the products of Forbrico, DeepSouth Chemical, Integrity Industries, CabotSpecialty Chemicals, Sun Drilling Productswho has acquired the products of CoastalSuperior Solutions, and txi Energy Services.Each listing includes new and updated prod-ucts provided by each company with a descrip-tion of the product and the product’s generalcharacteristics.∆
