Biocides

Bacterial contamination of oil and gas production
systems is a serious production challenge. Bacteria
may have been introduced in many ways and over
many years—drilling well completions, reinjection
of produced waters for pressure maintenance, EOR
projects, workovers, hot oil/water treatments, etc.
It’s often impossible to determine the cause, but once
bacteria take up residence in a reservoir or production
system, they are difficult to eliminate. The good news
is that with Water Technologies & Solutions’ chemical
treatments, bacteria-related issues can be controlled
and production issues reduced.
It’s important to assess the locations of the bacteria in
a system. Water Technologies & Solutions’ technical
teams will collect samples of fluids and conduct
tests to identify and numerate the types of bacteria
in a production system. Based on the finding, select
chemistries and mechanical solutions are used to
attack the bacteria where they reside. Some colonies
of bacteria take root on the surfaces of the pipe, and
over time build a protective layer that allows them to
thrive. Some take root inside storage tanks, where they
metabolize organic acid and inorganic ions to produce
noxious gases.
What’s unique about Water Technologies & Solutions
is that wherever the issues reside, we have the
know-how to deliver the knockout punch to bacteria.
Specially designed formulations penetrate bacterial
films and destroy the active colony. Nano-filtration
systems can remove all bacteria from injected fluids,
effectively providing a green solution for water needs.
Our technical teams work in collaboration to deliver the
optimal system to address bacterial issues in a system.
By selecting the best program, Water Technologies
& Solutions will sterilize process water used in
fracking and water injection, helping to maintain the
highest levels of asset integrity. This contributes to
reduced operational costs due to challenges which
might include microbiologically induced corrosion
(MIC), H2
S generation and the subsequent issues that
arise, polymer degradation, filter plugging and safety
concerns attributed with bacteria.
Some benefits involved in biocide control include:
• Reduction of fouling from iron sulfide
• Reduction of sour oil and gas production
• Reduced levels of H2S, which cause real safety concerns when it accumulates in equipment and ponds
• Reduction of sour oil and gas production
• Reduced levels of H2S, which cause real safety concerns when it accumulates in equipment and ponds
