What are the benefits of using biological products in an oil production operation?

The major benefit is maximizing oil production. Other benefits typically include a reduction in maintenance expenses, wear and tear on pumps and equipment, as well as operating costs and, in some cases, federal tax credits, in addition to an improvement in oil characteristics, and flowline performance. Last, but not least, all our products are 100% safe to use and environmentally compatible.

What is the usual application method?

Almost all the treatments are pumped in without any modification to the existing well configuration. Treatments can either be pumped down the annulus or applied through the tubing depending on the well setup and type of lift. Some setups may require coiled tubing to spot pills in horizontal legs, although, in most cases, it is unnecessary.

How do our biological applications differ from techniques like hot oiling, chemicals and cutting?

The standard hot oiling, chemical and cutting oilfield practices are used as a temporary patch to production problems. Biological programs, on the other hand, are long-term solutions which benefits can last for months, including their continued effects producing significant changes in the near-well-bore area and in the resulting oil quality. Viewed in another way, the microorganisms set up shop near the well­ bore area to produce ketones, alcohols, surfactants and other chemical reactants, which eliminate the operator's need to supply them - very much like having a natural chemical factory in each well!

Is there any operating restriction associated with the use of our products?

For the most part, there are very few..BioActive ChainBreaker products when it comes to temperature it’s not a factor while the chloride content, we have ChainBreaker microbes working in wells completely saturated at 25% or 250,000ppm..Overall, our products are much safer - having fewer handling and use restrictions - than most common oilfield methods, such as chemicals, hot oiling methods, and diesel or xylene flushes.

How can one product produce these results over a wide variety of production practices in a multitude of different production scenarios?

The products used for your oil field project are custom blended according to your specific well conditions and the desired results. Derived from the latest microbial technology, our products are designed to maximize your production through timely repeated treatments.

Where has this technology been successfully applied?

Since its commercial introduction during the 1930s, these products have been used all over the world; from Venezuela to Malaysia, from China to Canada, from the mid-Continent to the Slope, and from the Gulf of Mexico to the Gulf of Guinea. To date, successfully treated wells in the thousands, worldwide.

Is special equipment required?

No. The equipment required is dependent upon how the application is carried out. Most applications can be completed with standard oilfield equipment, such as our service units if needed. Note that workover rigs are not required.

What is a 'typical' pumping well application?

A typical down hole application for Paraffin, Asphaltene, scale and corrosion reduction, including emulsion breaking, would consist of the following: Batch treat down the backside of each well with highly concentrated live ChainBreaker microbes flushed with a minimum of 1 barrel of produced water or KCL-treated water to ensure that the microbes pass the down hole pump and settle into the cellar of the well. Once in the cellar, the microbes begin their duplication process. This batch treatment recommendation would be repeated within two weeks to make sure that the microbial culture is well established in the cellar and the cleaning is continued in the well. With each treatment, a recommended two-day shut in would be given. Communication between the well operator and Bioactive technical staff would determine if, after the first 2 treatments, a monthly treatment would be sufficient to maintain the well's performance. Generally, looking into the pig sender for cleanliness, monitoring the load on the rod string and the daily production plus oil and water analysis should determine if treatment adjustments and interval duration need to be adjusted.

Considering that what already exists in the well is harder to break down, the microbes not only stop any future build up, but they work on softening and removing the original accumulation. By starting a new well program and treating at two-week intervals, possible production fluctuations are to be expected as scale, paraffin and asphaltene are softened and removed. In most cases, other than with high producers, monthly treatment intervals would maintain the well's performance and long term objectives.

Do the products need nutrients or other additives for maximum results?

No. These ChainBreaker microbial products are delivered dormant in a ready-to-use form; All that is needed is 24hr activation period before pumping. In most cases, the micro-organisms are chased with production water or KCL (2-3%). In water sensitive formations, our technical staff will develop alternative custom methods to respond to individual requirements.

How do the products work? What are the mechanisms?

Production stimulation works through several mechanisms: removal of hydrocarbon deposits from the formation, reduction in oil viscosity and changes in wettability. These changes are produced by the micro­ organisms' by-products, which include bio-surfactants, solvent molecules and other agents.

Will BioActive product(s) damage my wells?

No.

Will BioActive products cause souring or a H2S production?

No. Souring and production of H2S (hydrogen sulfide) are caused by a special group of micro-organisms called sulfate-reducing bacteria (SRB). Our products do not contain SRB’s and using our products does not lead to souring. In fact, we have ChainBreaker microbial treatments reducing H2S from 50,000ppm(5%) to 35,000ppm(3.5%) after 3 treatments.

How long will a treatment last?

The lasting effects of a treatment depend on its type and are well specific. However, repairing frac damage, for example, can last for the life of the well, while the beneficial effects of stimulation treatments normally last between 3 and 5 months, and sometimes longer. Maintenance treatments differ; they are usually much smaller than stimulation treatments and should usually be repeated every l to 2 months.

Why do I have to shut my well in after treatment?

Biological treatments work best if the microbes are allowed to grow or "colonize" the wellbore and formation before resuming production. The shut-in period normally lasts between 2 and 7 days, depending on well conditions and the treatment design. Also, depends on their fluid levels and if they are horizontal wells. During this growth phase, the micro-organisms multiply and produce beneficial products.

Will microbes work in depleted wells or wells with a high water cut?

Yes. Biotechnology can be effectively applied throughout the life of the well. Each well must be evaluated separately for its potential. BioActive's technology can be successfully applied to new wells, and to depleted wells with a high water cut.

Will microbes work in high-rate wells?

Yes. Impressive results were obtained from the treatment of wells producing more than a thousand barrels of fluid per day. In fact, production from one well peaked at over 5,000 barrels of oil per day after its treatment!

Will microbes work in water Injections Wells and Water Floods?

Injection pressure reductions are generally noticed when microbes are used on injection wells resulting in the elimination of restrictions around the perforations and into the formation, as scale and hydrocarbon are reduced. On water floods, microbial treatments assist in the release of oil molecules from the rock face in the formation, thus increasing the life of the well; as well as in the elimination of several production problems and costs by preventing them from occurring. Microbes can add several years to the life of a well, allowing the producer to profit from more recovery.

Do Microbes work well to remove Heavy Tank Bottom Sludge?

Many oil companies throughout the world have had their tank bottoms removed by simply using microbes, which rejuvenate the heavy hydrocarbons. Using the method of treating microbes directly into the tank and agitating it by mechanical means in very large tanks, or in some cases, through the continued use of the field production tank as an agitation, provides a very safe and cost-effective means of elimination for tank bottoms. In most cases, the gains made from rejuvenated saleable hydrocarbons completely offset or reduce the cost associated with the treatment and services.
