Fracturing & Waterflooding

One of the most promising and most cost effective areas of interest for CarbonSeal™ is in Fracturing. One major oil company has been using CS to increase production for several years with amazing results. In our own preliminary tests, we poured CS down two non-productive wells, then let it rest for two weeks to work itself into the formation. The CarbonSeal™ successfully drew enough oil into the pipe to restart production.

When waterflooding, a 1% mixture of CarbonSeal can be added to the formation water at the injection well to enhance hydrocarbon recovery.

Remediation

CarbonSeal™ can be used to clean up and restore land damaged through environmental accidents by application directly to the soil, swamp, marsh or coastline. When the degradation requires it, the soils and organic materials should be stripped and loaded into a slurry vat for treatment. This vat can be any open container sufficiently large to hold the volumes being treated.

When the contents are slurried with the CS, then stirred or mixed to allow permeation of the CS to all the hydrocarbon molecules which have made the soil sterile, then allowed to "steep" as the CS separates the hydrocarbon molecules from the organic slurry and "floats" the oil contaminants above the CS, the oil products can then be drained and reincorporated into the petroleum company's system, helping to "pay" for the CS. The CS is either drained or collected for further cleansing or odor remediation uses, with the soil or marsh material being returned to its original location and production.

If a spill is so extensive as to not allow mechanical extraction and reapplication of the cleansed soil, a different process of applying CarbonSeal™ to the contaminated site is utilized. Heavier concentrations, if needed when determined onsite by our engineering representative, are applied as a "cap" to the soil.

When CS is applied to dry soil or marsh lands, the same baseline application as that used in cleaning interior tanks should be used, i.e. two cubic inches per one square inch of surface to be covered. "CarbonSeal Land Rule of Thumb": to clean 1,000 sq. ft. spill area requires approximately 167 gallons of CS to return soil to its pristine condition.

In extreme cases, anaerobic bacteria can be added to the process, which operates in conjunction with any remaining soil bacteria to assist in breaking down the hydrocarbons as they are attacked and bonded by the CS. In these instances, the CS is applied in a heavier concentration as it is left on the ground where it biodegrades after the hydrocarbon molecules have been consumed by the bacteria. This usually will take place within a thirty day time frame. A soil analysis can be performed to determine if the adding of commercial grade humates to the soil is necessary to return the soil to its original fertility level.

Rig Cleaning

As an EPA-approved de-greaser, CarbonSeal is especially effective cleaning oil rigs and platforms. Completely biodegradable and all-natural, it can be used in even sensitive areas without fear of environmental impact. Just put it in your powerwasher. It has a low-suds formulation that is easy to work with. CarbonSeal's grease-cutting capabilities work best when heated to around 180 degrees.

Pipeline & Storage Applications

When used in lieu of a mechanical pipeline pig for cleaning oil pipelines, storage batteries, refinery towers, oil transports, bunkering tanks and/or loading facilities, CarbonSeal™ (CS) is applied either through ingestion into flow of the oil moving through the pipeline or containment system, or is applied externally as a cleansing solvent in its water carrier.

When CS is being used to clean paraffin buildup in pipelines, it is injected into the oil stream at the head of the pipeline via a centrifugal or mag pump. The CS in solution should be at a 6:1 water to CS ratio. This same solution rate applies when used for any internal cleansing application.

When cleaning bunkers, storage tanks, ship holds, etc., CS should be applied via a spray application whenever feasible. The hydrocarbons will "dissolve" while the CS will flow to the lowest point of gravity, allowing the hydrocarbon material to be removed for refining and sales.

At this point, since the CS has a water carrier, it will separate from and settle under the hydrocarbons, allowing for suction removal or gravity discharge via a lower drain. The CS will naturally be on the lowest level of the separation, with hydrocarbon products "floating" above it.

When CS is used in an external cleansing capacity, a 10% CS solution is satisfactory. CS collected from a pipeline or "tank" cleaning application can be collected after separation and recycled for cleansing usage on outside deck work and metal surfaces.

The add solution/flow rate varies upon the region where the oil products are being produced with the resulting variance in quality and classifications of the oil products, its paraffin content, API, viscosity, percentage of cracker bottom residuals, etc. all considered in the equation.

We will be glad to assist a qualified client in demonstration applications so that individual application and concentration rates can be determined in situ. As an initial rule of thumb, the formulation for application is 1 gallon of CarbonSeal™ Concentrate to 2,973 barrels of crude flowing through an obstructed pipeline.

In the pipeline application, a simple separation battery at the terminus of the pipeline similar to a wellhead saltwater separation process will be the easiest method of separation of cleansed oil products from the CS. The CS is injected into the pipeline either by a centrifugal or mag pump having a flow rate meter. The CS will be mixed throughout the pipe during transit.

As the oil and CS are moving through and cleansing the pipeline, and thereby increasing the effective interior diameter, the refining process for the oil is already commencing.

The CS will decrease the oil's viscosity while it is in transit in the pipeline, further reducing the refining process's time and costs, as well as pipeline transit costs!

After the initial cleansing application of CS has opened and freed any hydrocarbon buildup and obstructions in the pipeline, ongoing applications of CS in the pipeline will maintain the free flow of oil and avoid additional paraffin buildup in the pipeline, while decreasing the costs of pipeline maintenance, pumping and refining costs dramatically.

One First-Tier world oil company conducted tests of CS in their European pipelines and determined that by purchasing and using $38,000 of CS per week, they saved over $600,000 per week in their pipeline pumping, maintenance and refining costs. While this is a phenomenal cost savings, the European crude may have a slightly different rate of return on investment than other locales' operations would have, due to the different chemical and solids makeup and the qualities of oils from different regional sources.

Still, the basic model holds true in the positive application of CS to any oil company's operation with up to a 12:1 return on investment. There is no other product known to produce this kind of savings, nee net profit.

Petroleum companies currently using CS include Unocal, PeMex, British Petroleum and the national Ecuadorian petroleum corporation.

The Ecuadorian pipeline is a classic case in point: The Ecuadorian crude is a very heavy, sour crude, thick with paraffin. It is being produced at a high and cold altitude with the pipeline running up and over the continental divide 15,000' high in the Andes Mountains. This caused an increase in the oil's already thick viscosity with resultant pumping costs being extremely high, having a minimal amount of crude flowing through the impacted pipeline.

CarbonSeal™ was added to the crude at the head of the pipeline. The CS cleaned out all the interior paraffin buildup increasing the pipe's aperture, dramatically decreased the viscosity of the crude oil, initiated the refining process in transit and lowered their pumping and refining costs significantly.

CARBONSEAL™ PROTOCOL FOR MIXTURE IN CRUDE PIPELINES

  • CarbonSeal™ solution is 1 part CS in 6 parts water
  • 2400 liters per hour of CarbonSeal™ treats 5500 barrels of crude flow per hour = 90.22 gallons of CS concentrate per hour
  • The pipelines described were 14" - 16" transmission pipelines, which were cleaned to bare metal walls, while the separated CarbonSeal™ was gathered at the end of the pipeline.

This application is based on the company's experience with Ecuadorian crude. The treated crude oil's API rose from 20 to 40 as a result of the use of the CarbonSeal™ treating the pipelines. Similar applications of CarbonSeal™ are effective on all petrochemical refining applications where petroleum by-products are built up, whether transmission, refining or loading and transportation.

The crude oil has the refining procedure initiated during transportation through the pipelines by the inclusion of the CarbonSeal™, with the preliminary cracking process already being accomplished by the time the oil is delivered at the terminus of the pipeline. This has an additional effective cost benefit for the refinery.

Separation & Cleaning of Natural Gas

One company has been using CS in the separation, cleansing and drying process of natural gas in the Philippines with the resultant wet hydrocarbons being collected for revenue instead of being separated and flared, allowing the high-end distillates to be used to increase their corporate bottom line income instead of lighting the Philippine night sky.
