“Lecture Title: Designing Optimal Wells with Inflow Control Technology”

Lecturer’s Name: Kåre Langaas Lecturer’s
Employer: Aker BP ASA

Abstract: The lecture presents a systematic approach to continuously improve the lower completion design process, especially relevant for long horizontal wells with sand screens and inflow control technology (ICT). ICT enables optimal inflow into a well and helps control unwanted fluids. The potential is enhanced value and environmental benefits such as reduced CO2 emissions. Since the first SPE paper on ICT in 1994, the industry has evolved towards autonomous inflow control technologies (AICT). Langaas has managed flow performance testing of multiple AICTs from 2015-2023 as well as the correct modelling and evaluation of ICT wells in the reservoir model. The achieved improvements are a result of open collaboration with several technology vendors and inter-disciplinary teamwork. The success recipe applied for more than 40 horizontal branches consists of eight steps. Each step will be explained through examples.

1. Understand the reservoir and the key objectives for the well.

2. Understand and chase improvements in ICT.

3. Make a mathematical model of the ICT.

4. Pre-drill design studies of the well. Understand the best ICT and establish the lower completion strategy.

5. During drilling, update the understanding and models according to the actual drilling result. Update the design and position any in-well tracers optimally.

6. After start-up, secure good well surveillance including a tracer-based (or mechanical) production log.

7. Perform history match of well performance to compare the lower completion model with the observed data, incorporating the inflow estimates.

8. Learn and improve. Key Takeaway from the Lecture: A systematic approach to designing better wells.

Biography: Kåre Langaas is a Senior Advanced Reservoir Engineer at Aker BP. Langaas has a PhD in physics from the University of Bergen, in close collaboration with the University of Oxford, and has 30 years’ experience within reservoir technology research, reservoir engineering, field developments, and reservoir management. He was the Chief Reservoir Engineer for Det Norske and Aker BP from 2015-2020 and has since been Principal Advisor for lower completion design and in-well tracers. Langaas is the author/co-author of more than 25 papers/publications and has been the responsible/driver for Alvheim area testing/deployment of AICT and tracer technology, contributing to the Norwegian Petroleum Directorate IOR prize for 2018. Langaas is a member of SPE.
