Q: What are the benefits of using Drilling Specialties Company's biological products in my oil production operation?
A: The major benefit is increased oil production. In addition to the increased oil production, operators usually see reduced maintenance expense, reduced wear and tear on pumps and equipment, improved oil characteristics, improved flowline performance, lower operating costs and, in some cases, federal tax credits. And of course, all the products are safe to use and environmentally compatible.

Q: How are the products applied?
A: Almost all treatments are bullheaded in without modifying 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. In some cases coiled tubing is used to improve placement; however, it is usually unnecessary.

Q: How do these new product applications differ from techniques like hot oiling, chemicals and cutting?
A: These standard oilfield practices are used to temporarily fix production problems. Biochemicals are quite distinct from these methods in that they are a long-term solution whose impacts endure for months at a time and work continuously to achieve significant changes in the near-well-bore area and in the oil itself. Viewed in another way, the biochemicals set up shop in the near well-bore area and produce ketones, alcohols, surfactants and other chemical reactants which eliminate the need for the operator to supply them. It’s like having a chemical factory in each well.

Q: Are there any operating restrictions to utilizing biochemicals?
A: Very few. Temperatures can be as high as 270°F and chloride content can be up to 10% (100,000 ppm). The biochemicals have fewer safety restrictions than chemicals, hot oiling methods, diesel or xylene flushes and most other common oilfield methods.

Q: How can one product line produce such a wide variety of results including increased production in a multitude of different production scenarios?
A: The products are proprietary blends of biologicals and biochemicals specially formulated for your specific downhole application. Years of research and development in the field of biotechnology have allowed us to develop customized products with far-reaching benefits over traditional methods of application. One treatment with our B-Chem™ 6 product line can produce far better results and save valuable resources than using many other chemicals and methodologies.

Q: Where has this technology been successfully applied?
A: To date, successfully treated wells number in the thousands worldwide. As always, our customers’ confidentiality remains a priority, but we have a full range of success stories to share.

Q: Is special equipment required?
A: No. The equipment required is dependent on how the application is being achieved, but all standard applications can be completed with standard oilfield equipment such as vacuum trucks. Workover rigs are not required.

Q: What is the cost of the product for a typical application?
A: In the worldwide oilfield, "typical" is hard to find. Perforation height, formation porosity, oil characteristics, product concentration and formation penetration all factor into the treatment equation. If one assumes a 50' perforation height, a 3' 0" formation penetration, a product concentration of 50,000 ppm, 25% porosity and average oil characteristics, the product usage in a one-time treatment will be 2.5 drums (135 gallons) of biochemical stimulant. A one-time treatment will produce results for 90-270 days, sometimes longer.

Q: Do the biochemicals need any other additives for maximum results?
A: No. The biochemical products are delivered in ready-to-use form with the necessary nutrients already in place. In most cases the biochemicals are chased with production water or KCl (2-3%). In water-sensitive formations, our technical staff will work out alternative methods on a case-by-case basis.

-
Q: How do the products work? What are the mechanisms?
A: Production stimulation works by several mechanisms: removal of hydrocarbon deposits from the formation, reduction in oil viscosity and changes in wettability. These changes are produced by the byproducts of the microorganisms which include bio-surfactants, solvent molecules and other agents.

Q: Will these biochemicals damage my wells?
A: No

-
Q: Will your products cause souring or production of H2S?
A: No. Souring and production of H2S (hydrogen sulfide) are caused by a special group of microorganisms called sulfate-reducing bacteria (SRB). Our products contain no SRB and use of our products does not lead to souring.

Q: How long will a treatment last?
A: How long a treatment lasts depends on the type of treatment and well specifics. Repairing frac damage can last for the life of the well. Beneficial effects of stimulation treatments normally last 3-9 months, and sometimes longer. Maintenance treatments are usually much smaller than stimulation treatments, and usually should be repeated every 1-3 months.

-
Q: Why do I have to shut my well in after treatment?
A: Biological treatments work best if the biochemical-producing microbes are allowed to grow or "colonize" the wellbore and formation before resuming production. The shut-in period is normally 3-7 days depending on the well conditions and treatment design. During this growth phase the microorganisms multiply and produce beneficial products.

-
Q: Will your products work in depleted wells or wells with high water cut?
A: Yes. Biological technology can be effectively applied throughout the life of the well. Each well must be evaluated separately for its potential. However, the technology can be successfully applied to new wells for initialization, and to depleted wells with high water cut.

-
Q: Will the products work in high-rate wells?
A: Yes. We’ve had impressive results from 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 we treated it!
