Biocides
Biocides are used in all stages of oilfield development, from the initial drilling of the wells and the day to day production of oil and gas, and in all aspects of the maintenance of the field. They play an important role in the life of an oilfield and are a valuable tool in ensuring that oil and gas are produced safely and reliably.
Application :
-
Oilfields Development
-
Water Treatment
GLUTARALDEHYDE Basd
NON-OXIDIZING COOLING WATER BIOCID
It is used in recirculating cooling water systems and closed loop systems to control microbial growth. The product is effective over a wide pH range against the microorganisms typically found in these systems.
FEATURES AND BENEFITS
-
Good on fungi, fair on aerobic, anaerobic, and algae
-
Excellent broad spectrum micro biocide
-
Does not adversely affect cooling water treatment components
-
Non-foaming
-
Compatible with halogen biocides
-
Dosing: 45 to 115 ppm maintenance dosage, max slug dosage is 225 ppm. Most water treatment applications base dosage on bacteria dipslide results.
-
1 gallon at 100 ppm dosage treats roughly 12,000 of water.

Stabilized Liquid Bromine
COOLING WATER BIOCID
Stabilized Chlorine Bromide solution used in recirculating cooling water systems to control microbial growth. The product is effective over a wide pH range against the microorganisms typically found in these systems.
Advantages
-
There are a few reasons to use this product instead of just sodium hypochlorite. It has a better kill in higher pH waters and it is more stable over time. Sodium Hypochlorite breaks down fast and quickly over a short period of time.
-
Feed rate: Free residual of 50 to 100 ppm surplus.
-
Control: 0.5 to 1.0 ppm bromine (total DPD chlorine x 2.25).
-
Single drum alternative to bromine/chlorine feed.
-
Excellent broad spectrum micro biocide.
-
More effective than chlorine at elevated pH.
-
Quick kill micro biocide.
-
Compatible with common scale and corrosion inhibitors
-
Tolerates pH >9
-
Stabilized liquid bromine biocide.
-
7.1% as Cl2 (16% as Br2).
-
Very good for control of aerobic bacteria; good for anaerobic bacteria, fungi, and algae at pH 6.0 to 9.0.

THPS Biocide
NON-OXIDIZING WATER TREATMENT BIOCID
THPS biocide is a kind of environmental-friendly water treatment microbiocide which is made of tetrakis(hydroxymethyl)phosphonium sulfate (THPS) solution. It can withhold sulfate reducing bacteria (SRB), most of aerobic bacteria including microorganisms that form biofilm in enhanced oil recovery process, production and other supporting systems such as water injection equipments, well water disposal facilities, water holding tanks, recirculating water treatment systems and pipelines. THPS biocide is also effective in controlling microbial growth in drilling muds and stimulation fluids for oil and gas wells. Tetrakis(hydroxymethyl)phosphonium sulfate is characterized by its low solidity point and good stability.
