Paraffin Control with Carbon Numbers from C40 to C58 in Oil Wells

Para-Bac™ products are used to control paraffin, corrosion, and scale in producing oil wells, as well as in microbial enhanced oil recovery (MEOR). Para-Bac is also used in above-ground production facilities to keep tanks, separators, and flow lines clean.

The Para-Bac product line includes:

  • Maintenance treatments that eliminate the need for hot oiling, solvents, paraffin cutting and hot water. 
  • Soaking treatments that clear perforations, remove skin damage, clear tubing and perform thorough well clean up that persists for months.
  • Stimulation treatments that increase daily production averages, impact formation flow characteristics, initialize flow, mobilize heavy fractions and increase net oil production. Increase in production can occur from 10% to up to 40%, and sometimes more.


Para-Bac is a proprietary combination of natural, facultative anaerobic biologicals and biochemical used in oil well operations to control paraffin chains of length C16 and above. Para-Bac can disperse, dissolve, and prevent paraffin deposition through its metabolic by-products, such as biosurfactants, organic acids, ketones, and alcohols. These same metabolic by-products also act to inhibit scale formation.

The products are targeted to, but not limited to, solubilizing different length paraffin chains, described as follows: Product PB PBX PBXX PBXXX

Chain C-16-22 C16-40 C40-58 C45-60+


These products are often used in combination for optimum performance. Application of Para-Bac can result in cleansing of the formation face, production string, flowline, production vessels, and tanks. Para-Bac also increases the oil’s ability to dissolve paraffin while decreasing its cloud point/pour point. Reservoir permeability in the wellbore region is also improved due to paraffin removal and biosurfactant production.

    Para-Bac comes as a ready-to-use liquid formulation and can be introduced to the well by batch or squeeze treatments. Batch treatments usually involve the product being applied to the annulus and flushed with clean lease or fresh water. For optimum performance, it is recommended that the well be shut in for one to three days after treatment however, this is not mandatory.

    Treatment begins with an inoculation to establish the bacterial population of the well system. Thereafter, at predetermined intervals, maintenance dose of Para-Bac can be added to maintain the colony of bacteria. Squeeze treatment applications are a function of fluid production, porosity, perforation interval, and desired depth of penetration. The well is shut in for three to seven days.

  • Handling and Safety

    Para-Bac meets EPA requirements for release into the environment. Special clothing or equipment are not required for handling Para-Bac. Routine sanitary hygiene practices should be observed. 

  • Shipping

    Para-Bac is shipped in two sizes, in 5 gallon containers (45 lbs), and in 55 gallon containers (495 lbs), F.O.B. Round Rock, Texas.
