Periodic Batch Treating

To keep an active colony of microbes thriving and expanding within the wellbore and formation, periodic treatment with microbes in a nutrient solution is typically once a month or based on the production of the well.

Microbial Energy ME-1 microbes and nutrients are mixed, then dispersed into a pump truck and wells are treated. After treatment, wells are normally put on circulation or shut-in overnight if unable to circulate to ensure that the microbes have a chance to colonize at an oil-water interface in the wellbore and formation.


Stimulation and Remedial Treating

Routine, periodic MEO/GR treatments are not the only type of treatment performed. Other methods allow microbes to be placed further into the formation in a shorter time, such as placing microbes in a frac pre-pad or in a gelled frac fluid itself. These methods allow for a larger microbe colony to be established.

The colony is established along the fracture flow conduit and the microbes are ideally placed to form an effective bio-reactor. Placing microbes in frac fluids decreases load recovery time and increases producing rates. An alternative is to squeeze the microbes into the formation in a separate procedure. This treatment may be a high rate squeeze using ball sealers to distribute the microbes into the formation matrix, or may be at a lower treatment rate down the annulus. On wells with near wellbore damage, large production increases have been achieved.


Microbial Migration MEO/GR Technology

An established microbe colony in the wellbore allows for migration deeper into the reservoir. Actual production increases support microbial migration and fluid viscosity reduction. Production rates increase before resuming a “pre-treatment” decline rate. The increased production rate and some decline rate results in increased ultimate recovery. Enhanced recoveries increase as soon as MEO/GR begins, however, recovery can be increased at all stages of reservoir depletion. Recovery is also increased due to an improved mobility ratio and improved relative permeability to oil/gas.

A special blend of bacterial cultures and surfactants selected and adapted in such histories as:

  1. Calcium carbonate scale
  2. Barium Sulfate scale
  3. Corrosion from iron sulfate scales
  4. Emulsion breaking
  5. Paraffin & Corrosion Control
  6. H2S and iron sulfide scale

In downhole applications the bacterial cultures are mixed with a nutrient mixture prior to injection into the bore hole. The liquid is injected under pressure to distribute evenly in the well. Use of this product can result in higher oil recovery from the well. M. E. LFH contains a surfactant to stimulate rapid bacterial reproduction and degradation.

Microbes are also available in Bio-remediation.
