Gas lift is a key lifting aid for mature oil producing wells to help reduce the fluid density in the wellbore and enable easier extraction of the fluid. It is a cost-effective technique for mature fields to maximize total recovered hydrocarbons. However, three main factors affect the efficiency of gas lift – namely the injection rate, the lifting depth and the gas lift valve (GLV) type/orifice size and setting. Over time however, issues can arise with the well that stop the gas lift from operating at maximum efficiency. There are non-intervention specialized techniques that can be used to diagnose the efficiency of gas lifted systems and provide recommendations on remediation and optimization. It is not only important to look at gas lift on an individual well basis, but also at the field level. Evaluating the potential of field level optimization via data driven workflows and nodal analysis can help maximize potential production.
At the end of this webinar, you will be able to:
- Describe the fundamentals of gas lift
- List the issues that can occur with gas lift and how they can be diagnosed
- Explain the gas lift optimization workflow on a per-well basis
- Describe the process of full-field gas lift optimization
- Adopt learnings from case studies of gas lift surveillance and optimization which could benefit your business
This webinar will cover:
- Gas lift principles and common issues
- Surveillance technology available to correctly diagnose gas lift systems without intervention
- Per-well and full-field gas lift review and optimization workflow
- Case studies
At SGS, we can help you improve your production optimization or cost reduction process to streamline delivery of oil and gas. Our integrated consultancy service uses data-driven analytics, and ScanWell’s unique surveillance equipment with advanced modelling capabilities. We use this combined data along with our production technologists experience, in conjunction with the operator’s team to provide key recommendations for remedial and optimization potential.
