Mono Trip Gas Lift (MTGL) Completion is an advanced well completion technique introduced by Baker Hughes, designed to significantly improve the efficiency and reduce cost of gas lift operations. In traditional gas lift completions, multiple trips in and out of the wellbore are required to install the lower and upper completion equipment. The MTGL completion technique simplifies this process by allowing the installation of the entire gas lift system and a packer in a single trip. Additionally, cementing operations, packer setting, and cleaning operations can all be done offline once the rig skids off to another well. This application drastically reduces well costs. The MTGL completion is particularly well-suited for small reservoir fields or brownfields where well economics are very low. With traditional completion techniques, the well cost would be so high that development of the field would not be economical.
Here are some key advantages of MTGL Completion:
- Single Trip Installation: The primary feature of MTGL completion is that it allows for the installation of all necessary gas lift equipment, including gas lift mandrels and valves, in one run into the wellbore. This significantly reduces the time and cost associated with well completion compared to conventional methods that require multiple trips.
- Efficiency and Cost-Effectiveness: By reducing the number of trips needed, MTGL completion minimizes the operational time, decreases the risk of operational mishaps, and lowers the overall cost of well completion.
- Cement Through Design: Special equipment within the MTGL system is designed to be tolerant of cement, allowing for installation of the production tubing and other tools before cementing the wellbore. This minimizes risks and streamlines the process.
- Integrated Design: MTGL systems are designed to integrate seamlessly with existing well architecture. They often include pre-installed gas lift mandrels and valves on the production tubing, ensuring that the system is ready for immediate use once installed.
- Operational Flexibility: MTGL completion provides operational flexibility by allowing for adjustments and optimizations of the gas lift system without requiring additional trips. This can include changes in gas injection rates or the replacement of gas lift valves if necessary.
- Enhanced Production: By streamlining the installation process and optimizing gas lift operations, MTGL completion can enhance hydrocarbon production rates, making it an attractive option for wells that require artificial lift to sustain or increase production levels. Studies have shown that MTGL completions can increase oil recovery by over 15% compared to traditional methods.
- Reduced Risk: Fewer trips in and out of the wellbore reduce the risk of complications such as stuck pipe, well control issues, and equipment failures, enhancing overall well integrity and safety.
