According to a recent study, more than 50 percent of the world's energy currently comes from oil and natural gas. So how does Production Chemistry discipline play a role in this? Can we use the discipline to enhance or accelerate production? And what happens if we get it wrong? Will it have a detrimental impact on production?
The Production Chemistry threats to business are getting more challenging and frequent, reflecting the changing complexity of our Project and Operations portfolio (deeper water and complex interventions, longer subsea tie backs leading to colder fluids and more wax / hydrate challenges; or smaller tieback to hosts operated by others yielding compatibility challenges).
Production chemistry threats in Project and Operations represent a significant challenge to safe and competitive operations. The impact of getting it wrong can be severe, leading to deferrals and increased operational costs. The root causes of many of these deferrals can be attributed to late or unstructured production chemistry involvement during the Project stage and limited support during Operations stage.
The objective of this paper is to highlight the importance of understanding the financial impact of production chemistry decisions to safety, production assurance, operational expenditure (OPEX) and capital expenditure (CAPEX) for Project and Operations. Moreover, this paper will highlight the criticality of engaging production chemistry at the appropriate project phase to get the desired outcome. This paper provides a number of case studies. In a number of cases, production chemistry engineers correctly evaluated the project threats during engineering design, leading to a correct selection of preventative barriers which proved to be financially favorable, and reduced HSSE risks throughout life of the asset. In addition, one case study describes the operational experiences where the impact of production chemistry was incorrectly assessed and a production loss was incurred during Operations stage.
Based on these case studies, production chemistry engineers should be cognizant of the impact of their decisions on the projects including threat assessment and barrier selection throughout the project lifetime. In addition, the production chemistry engineers should be able to effectively communicate their technical decisions and associated reasoning and values provided with the project stakeholders.
