Definitions
- a drilling fluid such as a drilling mud
- a drilling mud When a drilling mud is used, it is continuously circulated from a storage area on the surface, downward through the drill pipe, and then upward through the borehole to the surface.
- the purpose of the mud is to remove drilled solids, such as cuttings and formation carvings, from the borehole to the surface.
- the fluid acts not only as a carrier, but also serves to cool and lubricate the drill bit, and to prevent pressure from being lost if a void or high-pressure gas pocket is encountered.
- drilling fluids for maritime drilling are more environmentally friendly than drilling fluids for land based use, but even so, most drilling fluids and muds contain a number of components, including barium, hematite, iron sulfite, and the like as weighting agents.
- Drilling muds and drilling fluids are typically mixed with oil to produce the final form of mud.
- the oil component is known as synthetic oil.
- synthetic oils exhibit minimal toxicity toward aquatic life and possess desirable rheological and filtration control properties for use in drilling fluids as compared to ordinary oil.
- the use of synthetic oils, particularly oleogomerized olefins, for drilling fluids has recently been patented these are referred to a synthetic oil based drilling muds or (SBM).
- SBM synthetic oil based drilling muds
- Mercer et al. in U.S. Pat. No. 5,096,883 discloses the use of compositions consisting essentially of branched paraffin having between 16 and 40 carbon atoms per molecule (such as the hydrogenated dimer of 1-decene) for this use.
- Patel et al. in U.S. Pat. No. 5,189,012 discloses the use of compositions comprising branched chain oligomers.
- Drilling muds are usually classified as either water-based muds or oil-based muds, depending upon the character of the continuous phase of the mud, although water-based muds may contain oil and oil-based muds may contain water.
- Water-based muds (WBM) conventionally comprise a hydratable clay, usually of the montmorillonite family, suspended in water with the aid of suitable surfactants, emulsifiers and other additives including salts, pH control agents and weighting agents such as barite. The water makes up the continuous phase of the mud and is usually
- Oil-based muds generally use a hydrocarbon oil as the main liquid component with other materials such as clays or colloidal asphalts added to provide the desired viscosity together with emulsifiers, gellants and other additives including weighting agents.
- Water may be present in greater or lesser amounts but will usually not be greater than 50 percent of the entire composition; if more than about 10 percent water is present, the mud is often referred to as an invert emulsion, i.e. a water-in-oil emulsion.
- invert emulsion fluids the amount of water is up to about 40 weight percent with the oil and the additives making up the remainder of the fluid.
- Oil-based muds were traditionally formulated with diesel oil or kerosene as the main oil component as these hydrocarbon fractions generally posses the requisite viscosity characteristics. They do, however, posses the disadvantage of being relatively toxic to marine life and the discharge of drilling muds containing these oils into marine waters is usually strictly controlled because of the serious effects which the oil components may have on marine organisms, particularly those which are commercially important for food. For this reason, offshore drilling rigs must return oil-based muds to shore after they have been used whereas water-based muds may generally be discharged into the ocean without any deleterious effects. The recycling of the OBM has become extensive and therefore in that respect an environmentally desirous outcome of the environmental movement. While the reuse of the OBM is environmentally friendly the use of diesel as the oil phase has a deleterious effect in that oil is left on the cuttings, which are discarded overboard.
- OBM's may be made environmentally acceptable by the use of oils which posses low inherent toxicity to marine organisms and good biodegradability. These properties are associated in hydrocarbons with extremely low aromaticity. For these reasons, drilling fluids based on linear paraffins, olefins, alkanes and esters are considered desirable, and these are known as synthetic based muds (SBM). In recent years the environmental impact of overboard cuttings disposal both SBM and WBM has come under scrutiny by the regulatory environmental agencies.
- This invention addresses the further remediation of the cutting produced from use of SBM, WMB, and OBM. It will be utilized in conjunction with and after the solids control equipment that would already be on the drilling rig
- An object of the present invention is to provide an additive, which can be added to drilling fluids that have been used in the drilling process to make the organic contaminates found in SMB's, WBM's and OBM's available to indigenous marine life as a food.
- Another object of the present invention is to provide and environmentally safe method for remediating drilling muds so that "mounding” does not occur on the sea floor near drilling rigs, creating “dead zones” for marine life near the rigs.

Therefore, theoretically a system with biodegradability factor of 80% in 28 days could be improved to 1 to 3 days. It is commonly assumed that if carbon-bearing material exits the environment within 3 to 7 days then it has been consumed and the carbon utilized as bio fuel.
- the most preferred composition according to this invention of is a mixture an alkali metal oxide, most preferably lime (preferably hydrophobized lime), and a cell transport support agent of Fulvic acid.
- This invention by the addition of the prescribed non-hazardous chemical treatments in the prescribed manner, convert the entire mass of drill cuttings to a food source (the hydrocarbons, carbon-based polymers, cellulose etc), a source of minerals (calcium, magnesium), a source of nutrients (enzyme like cell transport agent) necessary for growth of the available acclimated micro and macro organisms.
- a food source the hydrocarbons, carbon-based polymers, cellulose etc
- a source of minerals calcium, magnesium
- a source of nutrients enzyme like cell transport agent
- This process eliminates the organic contamination both known and unknown that occurs in the drilling process and the "mounding" effect characteristic of the all offshore drilling.
- the drill cuttings treated under the embodied process preferably those generated from the use of synthetic oil based drilling fluid and all water based fluids, are converted into a fine silt like solid which is carried away from the drilling rig by the ocean current and very slowly descends. As the material very slowly descends the finely dispersed and micronized organic contaminants which have been combined with a cell transport and a mineral carbonate are consumed by all available micro and macro organisms natural to the sea environment at the given location.
- the byproducts of this process are dirt, sand, clay, barite, salt, carbon dioxide and a small amount of biomass, which are natural excrement's of all sea life. This process should take place within 1 to 7 days of initial exit from the rig.
- the invention relates to a method for treating drilling fluid with organic contaminates comprising the steps of: mixing the drilling fluid with organic contaminates in a high shear mixer; adding to the drilling fluid a solidification agent which expands when hydrated and electrolytically attracts said organic contaminates to its surface; adding a cellulosic additive, wherein the celluslosic additive is a member of the group: ground wood, ground corn, ground wheat, ground cotton, ground rice, ground hemp, ground sugar cane, ground nut shells, ground carboxy methyl cellulose, pulverized recycled paper, and most preferably hibiscus canabinus, in an amount between 1 and 50 wt % based on the amount of said organic contaminate in the drilling fluid, forming a mixture; adding a cell transport agent to the mixture in an amount between 0.5 wt% and 10 wt% based on the amount of said organic contaminate in the drilling fluid, wherein said cell transport agent is capable of transporting large organic molecules through cell walls and neutralizing said mixture to
- the high shear rate mixing preferably has a duration from 5 minutes to 2 hours per batch, more preferably 10 minutes to 1 hour per batch.
- the mixing is preferably performed at a temperature between 210°F and 500°F. If a continuous mixing process is used, the preferred flow rate is 30-40 MT per hour.
