This paper discusses the use of specific ion electrodes for determining the anion-free water. This method is simpler and more accurate at low electrolyte concentration than ordinary chemical methods. It is potentially useful for oilfield application and laboratory automation. The mobility of this water is also examined under forced conditions with pressure gradients. It is expected that by using the methods developed in this paper, one may obtain a better understanding of the clay properties. 

Test results from various vaoe type mist extractors showed that they remove almost all particles larger than 25 microns in diameter. This will produce efficient separation in most oilfield applications. 

Oilfield applications -polyacrylamide additives [ACRYLAMIDE POLYMERS] (Voll)... 

Polyacrylamides are used in many other oilfield applications. These include cement additives for fluid loss control in well cementing operations (127), viscosity7 control additives for drilling muds (128), and fracturing fluids (129). Copolymers [40623-73-2] of acrylamide and acrylamidomethylpropanesulfonic acid do not degrade with the high concentrations of acids used in acid fracturing...

Amine ethoxylates are found in a wide variety of applications as corrosion inhibitors (oilfield applications), emulsifiers (asphalts), and as wetting agents processing aids, antistatic agents and lubricants (textiles).

A depol5nnerized carboxyl alkyl guar with a degree of substitution of up to 3 carboxylic groups per sugar unit can be used as a scale inhibitor in oilfield applications (40 This is a biodegradable scale inhibitor which is effective under severe scaling conditions. 

Pol5mciers having phosphorus-containing end-caps, especially polymers comprising acrylic acid, are widely used as scale inhibitors, particularly in oilfield applications (9). 

These requirements eliminate many interesting possibilities for scale inhibition chemistry that are very useful in other crystal growth applications. For example, polymers containing hydrophobic character can be quite effective for inhibiting crystal growth in a simple system, but are generally not suitable for oilfield applications. 

As can be seen, there are many water-soluble polymers for potential use in oilfield applications. Partially hydrolyzed polyacrylamide and xanthan gum are the most commonly employed in EOR applications [40]. Therefore, this review will concentrate on these polymers in addition to hydrophobically associating polymers. 

Comonomer reactivity ratios for AMD and NaAMPS are given in Table 5 (147). AMD/AMPS copolymers and AMD/NaAMPS copolymers maintain their anionic charge at low pH and have a high tolerance to many divalent cations. They are used as flocculants for phosphate slimes, uranium leach residues, and coal refuse. There are also many oilfield applications. 

To illustrate the above, inhibitor evaluations by means of the so-called "Wheel Test [iO] fail all three quality criteria. This test has in the past been used extensively to evaluate corrosion inhibitors for use in oilfield applications. The results are always based on weight loss and are, therefore, not unique. They are not relevtmt, because as the test bottles turn on the wheel to which they are affixed, the flow regime or agitation is not defined. The results are also not predictive, because the controlling variables do in general not reflect field conditions. Disregtirding these most basic quality criteria has in the past been, tind still is, a major resison for costly failures in the field of oil tmd gtis production.

General information. Glutaraldehyde is a 5-carbon dialdehyde that has seen extensive use in industrial water treatment applications. In addition to its use as a biocide in oil and gas operations, it is also used in cooling water, paper making, and preservative applications, medical instrument sterilization, and as a non-biocidal crosslinker for leather. X-ray films, and enzyme immobilization. It is often used in oilfield applications in combination with other non-oxidizing biocides such as QAC s and formaldehyde and is compatible with the oxidizing biocides typically used in cooling water applications. 

General information. Chemically, THPS is tetrakishydroxymethyl phosphonium sulfate. It is used in oilfield applications, but has also been used in traditional water treatment applieations as well as some non-biocidal applications. A closely related product, THPC (tetrakishydroxymethyl phosphonium chloride) is a widely used flame retardant. THPS is used on both the injection and production side of an oilfield and has a unique mechanism of action which enables it to perform three functions in an oilfield. THPS will kill microorganisms, reduce hydrogen sulfide concentrations and react with and dissolve iron sulfide.
