organophilic lignite

What is organophilic lignite?

A organophilic lignite that has been coated with a chemical that renders it dispersible in oil. The treatment is sometimes accomplished with a kind of quaternary amine compound.

Advantages of organophilic lignite:

Mixes simply

Controls HTHP filtrate

Works altogether kinds of Oil Base Muds and synthetic Base Muds at variable concentrations

Increases the stability of fluids to temperatures above 400 F

Provides supplemental emulsion stability at high temperatures

Organophlic lignite is amine treated lignite work in oil drilling

The treatment is usually accomplished with a type of quaternary amine compound.Organophilic lignite (amine treated lignite) is a filtration‐control additive designed for use in all oil‐base systems, as well as synthetic‐base systems. It is an effective alternative to asphalt or gilsonite where their use is undesirable.  Amine treated lignite effective and applicable in all oil‐ and synthetic‐base drilling fluids, and is compatible with other additives.

How to product Organophlic lignite – amine treated lignite (Versalig)

50 parts of lignite, dry basis (66.8 parts as received) were mixed with 150 parts hot water and 7.5 parts sodium hydroxide in a Waring Blendor for five minutes. In a separate Waring Blendor jar there were mixed 130 parts of hot water, 18.5 parts of concentrated hydrochloric acid (37% HCl) and 55 parts the Partial Amide 0.7. The lignite solution was added to the Blendor jar containing the HCl and Partial Amide 0.7 and mixed 7 minutes. The slurry was then dried at 150° F. and the Organophlic lignite – amine treated lignite (Versalig)  ground to a fine powder.

The invention provides a novel process of preparing Organophlic humate derivatives wherein: an aqueous solution of a humic acid-containing material is prepared with an alkali metal or ammonium base; an amine containing at least 16 carbon atoms and at least one functional group per molecule selected from the group consisting of primary amino, secondary amino, quaternary ammonium, and mixtures thereof, is mixed with the humate solution; an acid is mixed with the amine-containing humate solution in an amount at least sufficient to neutralize all of the alkali metal or ammonium base used to prepare the humate solution; and thereafter the organophilic substituted ammonium humate derivative is recovered.
