Key features and benefits
Unique — FLI is a unique method of well intervention using disposable fiber optics for data measurement and well profiling.
Fourth Line in Intervention — FLI is a fourth method of well intervention, alongside wireline, slickline and coiled tubing, offering clients an alternative low cost option for data acquisition. Instead of piggy-backing on other well intervention or workover activities, FLI can be quickly and independently deployed at low cost, any time. Fiber optic data capture is also faster, more reliable and more accurate than other intervention methodology, such as measurements taken using wireline tools and transmitted via copper wire.
Disposable — FLI’s fiber optic line and probe are disposable, so they completely degrade in the well environment over time. Once the data has been captured, the line is cut and ‘rig down’ is immediate. There is less risk of stuck in hole or lost in hole situations and no NPT associated with pulling out of hole.
Compact — FLI is compact and portable, ideal for offshore, onshore and remote locations worldwide. The FLI kit can be delivered to site on the back of a pick up truck onshore, or in a small container offshore, and be ready to run in less than an hour compared to around ten hours for slickline. It uses bare fiber optic line rather than being encased in a carbon rod or other media. It requires no heavy, bulky, costly tool strings, lubricators, slickline or other ancillary equipment which can be complicated and time consuming to rig up and down on site.
Fast — FLI is a plug and play system. It is taken onsite ready to run for rapid implementation. It takes two people around an hour to rig up and prepare the equipment on site. The survey can take as long as required and rigging down is immediate.
Low Cost — FLI is the most cost-effective method of downhole data capture available. FLI abolishes the need for teams of personnel and removes almost all of the mobilisation costs associated with conventional intervention. Compared to an onshore well intervention in the US, FLI offers an approximate 75% product cost saving and an approximate 90% operational cost saving offshore the US.
Low Risk — FLI is the lowest risk method of downhole data capture available. There is no need for high levels of personnel or support equipment and project logistics and time are significantly reduced. There is less risk of getting stuck in hole, less risk of lost equipment and no lost in hole charges. There is no non-productive time associated with rigging down and the cost savings are dramatic.
Active Technology — FLI can be upgraded with technology to enable tractor access to previously unobtainable depths and deviations. It can provide single point measurements and 4K HD camera surveillance alongside pressure, temperature and acoustic information.
Multiple Fibers — FLI can install multiple fibers. Typically a ‘Triple FLI’ deploys two single mode fibers and one multimode fiber simultaneously. This gives an optimised solution for performing DAS, DTS and single point measurements or video.
Well Access — FLI is deployed in vertical wells at an optimised speed of 8ft/s. Free fall speed is adjusted to the well conditions by varying the drag coefficient of the probe rather than its weight. FLI can access highly deviated and horizontal wells by a single trip tractor. Stop, start and speed control commands are sent from the surface.
Complete Lifecycle Solution — FLI can be used across the full lifecycle of the well, from exploration to production and decommissioning. It can perform low cost surveillance on an entire field of wells, leading to more efficient and safer recovery of hydrocarbons.
