How do you optimize the performance and maintenance of your wells? This question lingers in the minds of oil & gas industry players, as wells may record reduced productivity at one point. But that’s not the end of it all.
There are remedial options you can employ to improve performance. One of the best solutions is to apply well intervention techniques. Read this article to discover the three best well intervention techniques to restore and increase productivity.
- Wireline Services
As a light intervention, wireline involves running tools and other equipment in the well using slickline, braided lines, or electric lines. These tools aim to clean walls and perforate, log, and damp cement.
Knowing how to attach the wireline and understanding ‘weak points’ will save you from loss of equipment or other possible financial penalties. Working with Renegade Wireline Service professionals guarantees safety.
This technique can be used both offshore and onshore. However, offshore use might demand heavy intervention equipment depending on the type of offshore well. Wireline can run real-time data transfer from the downhole to the surface. Additionally, you can use wire lines to convey other sensors.
- Coiled tubing(CT) operation
This operation involves drilling continuous flexible pipes into the well. The pipes pass down well-servicing tools and liquids for cleaning purposes. You can opt for CT due to its ability to reach the inaccessible parts of a wall and its cost-effective nature compared to traditional methods.
You might also do a range of activities with CT, such as acid stimulation, fracturing, cementing, stuck pipe prevention, and retrieval. Other advantages of using this technique include:
- It’s time-saving as it doesn’t involve connecting and disconnecting pipe joints.
- It can work in live wells.
- CT reduces rig up and trip time.
- Hydraulic Workover(HWO)
This technique utilizes hydraulic cylinders to pull pipes in or out of wells. Using hydraulic cylinders makes it flexible to control pipe moments. HWO can be used in heavy-duty well activities, eliminating the need for large mast construction. Some activities that you can employ HWO for are:
- Large cleaning operations
- Big perforating operation exceeding tool weight limits for wireline requirement
- Production tubing repair.
- Heavy-duty oilwell fishing operations.
HWO is an excellent, well-service operation offshores and in areas where weather conditions can be harsh. Compared to CT, HWO can push high-pressure pipes in deep reserves. On the other hand, it’s more costly to operate HWO than a CT. Before making your pick, consider the unique requirements of your wells and the finances at your disposal.
Conclusion
Well-intervention techniques are essential in discovering the earth’s subsurface wealth in the oil industry. Invest in the three techniques in this article to unlock the full potential in your well. Ready to enhance productivity? Let experts help.
