Wireline fishing is an unplanned but often necessary part of Well Intervention operations. The retrieval of items, known as fish that may have become lost or stuck within the wellbore can range from simple recovery to extremely complex scenarios which require experienced field operators to resolve. In these situations production will often cease resulting in a locked-in/shut-in well.
Depending on the fishing scenario, a variety of tools attached to the toolstring can be run into the well to diagnose or retrieve lost or stuck items, in order to clean and safely return the well back into production.
Using small diameter slickline or larger compacted type braided lines, the tools deployed in wireline fishing cover a variety of functions, from taking impressions, basic pulling and recovery tools to spears and overshots.
Whatever the scenario, deferred production means loss of revenue which can be extremely costly. Having a reliable fishing package on hand to cover unplanned scenarios will greatly reduce the impact of downtime.
Strength and reliability are key factors when considering fishing operations, because of this we have designed our tools specifically to ensure safety and speed are always paramount.
LiMAR Wireline Fishing tools cover every deployment eventuality from Lead Impression Blocks, Bailers and High Power Magnets to basic Pulling Tools, Finders and Wire Grabs up to heavy duty options for stubborn tools with fish necks such as Heavy Duty Pulling Tools (HDPT) or lost fish without a standardised neck including Releasable Overshot’s & Releasable Spears. We believe that our retrieval tools are best in class using only the best materials including 130KSI strength alloy steel, designed to be used in prolonged heavy jarring situation.
As former field engineers, we understand the pressures of well downtime and the importance of retuning to production, quickly and safely. We offer a number of fishing packages which will cover most unplanned eventualities, resulting in less downtime and for those situations where bespoke engineering is required, we have a highly experienced technical team who will collaborate with the field personnel to produce an effective and successful fishing tool.
