About Crude Oil & Gas Operations
In the high-stakes environment of energy production, microbial activity is a constant, invisible threat to asset integrity and operational safety. Advanced biocidal solutions by Speciality Organics Pvt. Ltd. provides a robust defense against Microbiologically Influenced Corrosion (MIC), reservoir souring, and biofouling, ensuring your infrastructure remains resilient from extraction to refining.
Biocides & Corrosion Inhibitors
CR Shield® GGL 20
Glutaraldehyde based non-oxidizing broad spectrum biocide to rapidly eliminate bacteria and control biofilms in both drilling and production phases. Significantly reduces microbiologically influenced corrosion (MIC).
CR Shield® THPS
Tetrakis Hydroxymethyl Phosphonium Sulfate (THPS) based highly effective, environmentally friendly, and biodegradable biocide for controlling iron sulfide, sulfur-reducing bacteria (SRB), and souring (H2S). Non foaming also workd as scale inhibitor
CR Shield® QAC 50
Quaternary ammonium compounds (QAC) based biocide to control bacteria (including Sulphate Reducing Bacteria – SRB). Also works as an effective cationic surfactant for enhanced oil recovery (EOR)
CR Shield® S
Chloromethylisothiazolinone and Methylisothiazolinone (CMIT & MIT) based Formaldehyde Free Broad Spectrum Non Oxidising biocide
CR Shield® DPA-W20
Dibromo nitrilopropionamide (DBNPA) based Broad Spectrum Bactericide and Fungicide for Quick kill action. Used in Hydraulic Fracturing (Frac Fluids), Water Injection/Water Flooding, Drilling Muds & Packer Fluids, Pipeline Corrosion Prevention.
CR Shield® QAC BL-300S
Bronopol based Broad Spectrum Bactericide and Fungicide. Highly effective to control aerobic and anaerobic bacteria, particularly Sulfate-Reducing Bacteria (SRB), in water-based systems
CR Shield® TRA
Hexahydro S- Triazine (HHT) based Broad spectrum biocide generally used as liquid chemical scavenger for neutralizing Hydrogen Sulphide H2S by converting it into safe, non-volatile, and water-soluble by products.
