Oilfield bacteria are present everywhere water can be found in the hydrocarbon production process. Unchecked bacteria populations can result in operational issues through the upstream and midstream production environment. Starting at the producing formation itself, bacteria introduced into the formation during drilling, completion, or flooding can result in the plugging of the formation as well as the wellbore.
Though freshwater has traditionally been the primary vehicle for hydraulic fracturing well completion, a variety of stressors are driving exploration and production (E&P) companies to increase their use of produced water. These stressors include freshwater availability and use in E&P operations, increased costs associated with the acquisition of fresh water, and the costs and regulatory limits on the disposal of produced water.
Injection wells and drilling can be a quite confusing subject for those who are unfamiliar with oilfield operations. This short application spotlight is intended to provide readers with a brief overview of the terminology and processes associated with this subject.
