With an increasing number of wells sitting idle before production, it is more important than ever to optimize microbial control throughout the lifecycle of oil and gas operations. Since the price of oil began its sharp descent in June 2014, drilled but uncompleted wells (DUCs) have doubled to about 4,000. The longer a well sits idle, the higher the risk of contamination, making the microbial control program decision for drilling and completion engineers even more important.
