Ensuring hydrocarbon extraction remains effective

As offshore wells and reservoirs become increasingly complex and difficult to manage, the importance of monitoring and event logging is critical to ensure hydrocarbon extraction not only remains effective, but also cost effective.

Using traditional monitoring technology can be costly and risky, however inflow monitoring technology has emerged as an effective alternative. With no requirement for cables, connections or well intervention, and no use of radiation, the safety benefits of inflow tracer monitoring technology are significant. Costs are also kept to a minimum with no need for additional personnel or rig time.

These benefits will be the topic of discussion at the next Society of Petroleum Engineers (SPE) Aberdeen Section technical meeting, which will be presented by RESMAN UK and Maersk Oil UK.

Since the company’s inception in 2005, RESMAN has developed Intelligent Tracer Technology which addresses these risks and concerns and are custom-designed to achieve clients’ specific well monitoring objectives. The technology has been so well proven that it has been used in long horizontal sand screen wells across Maersk Oil UK assets.

RESMAN UK’s Senior Well Technology Engineer Erlend Faevelen will discuss the application of the Intelligent Inflow Tracers and will be joined by Hope Okhuoya, Senior Production Technologist at Maersk Oil North Sea UK. Together the duo will highlight how the technology has been used in long horizontal sand screen wells across Maersk Oil UK assets.

Prior to the February event, Mr Faevelen explained: “With the current status of the oil price, companies are looking to reduce cost and risk from their operations. At the same time data is required in order to maximise hydrocarbon recovery. The inflow tracer technology is seeing continued, growing interest despite the market situation. With the enhancements in our monitoring capabilities, RESMAN provides valuable data for reservoir management decisions, spanning years of interventionless production monitoring.”

Ross Lowdon, chairman of SPE Aberdeen, said: “This presentation will highlight a number of case histories such as confirmation of oil contribution, quantitative inflow distribution, and detection of gas and water producing zones. These examples will demonstrate the many benefits of this type of technology; minimised risk, long-term, cost efficiencies and HSE-friendly, and this promises to be an interesting presentation.”

Senior well technology engineer, Erlend Faevelen joined RESMAN Norway in 2010 as a tracer system designer before being reassigned to the well technology team. In 2014 Mr Faevelen relocated to RESMAN UK, Aberdeen where he is senior well technology engineer for projects in the UK and West Africa.

Hope Okhuoya has worked with Maersk Oil North Sea UK for over six years. As senior production technologist, Mr Okhuoya has been involved in projects ranging from production optimisation on FPSO operations, to completion design in various fields with subsea developments. Prior to joining Maersk he worked with Halliburton, ExxonMobil Nigeria and Enventure.

The presentation will take place on Wednesday, 25 February at Aberdeen’s Douglas Hotel, with registration from 6pm and the presentation commencing at 6.30pm.
