A New Biocide Enhancer for a Better Pipeline Treatment

Product Number: 51324-20576-SG

Biocide Enhancer (BioMETT) is a PETRONAS in-house chemical technology developed by PETRONAS Research Sdn Bhd (PRSB). BioMETT development took place back in 2015 where PRSB started to develop a biocide enhancer formulation that could enhance and boost up further the efficacy of current Tetrakis(hydroxymethyl)phosphonium Sulfate (THPS) biocide used by operation in mitigating corrosion problem inside crude oil pipelines due to Microbial Induced Corrosion (MIC). PRSB continued to test out the formulation in the actual offshore field environment where the BioMETT technology was piloted in two separate fields namely field A and B. The purpose of the pilot is to evaluate further the effectiveness of BioMETT formulation (a mixture of THPS and enhancer) in reducing the current biocide dosage injection between 30% to 40% at both pipelines while still showing the same efficacy as that of existing dosage in maintaining the acceptable low Sulfate Reducing Bacteria (SRB) count reading of <10 cfu/ml. Feasibility study was conducted to ensure the enhancer do not cause any corrosively effect to the pipeline on its own or when mixing with THPS. Furthermore, the mixture was also compatible with other oilfield chemicals and did not cause physical problems such as foaming and emulsion. Upon completion of the pilot, the results obtained showed a successful reduction of 30% in the biocide dosage, translated into 30% reduction in the biocide injection cost per every operational pigging (OP).

Enhanced Biocide Mitigation of Microbiologically Influenced Corrosion In Enhanced Oil Recovery

Product Number: 51317--9039-SG
ISBN: 9039 2017 CP
Author: RU JIA
Publication Date: 2017

MIC is a problem in the oil and gas industry due to seawater injection. Biocides lead to resistance by microbes over time. In this work, D-amino acids were used to enhance the tetrakis (hydroxymethyl) phosphonium sulfate (THPS) biocide against a tough field biofilm consortium.

MIC is a major threat to oil pipelines because it reduces the service life of pipelines and can potentially leads to catatrophes. Microbial communities commonly associated with pipeline corrosion include sulfate reducing bacteria (SRB), acid producing bacteria (APB), acetogenic bacteria and methanogens. In a field environment, SRB, APB and other microbes often live in a synergistic biofilm consortium. Sessile SRB are often the main culprit of MIC. They can utilize sulfate as the terminal electron acceptor and various carbon sources and elemental iron as electron donors. Corrosive APB biofilms are also a contributing factor in an acidic environment because they release H+ which is an oxidant.
