Tasman Oil Tools has a wide range of oilfield fishing and re-entry tools for the retrieval of lost or damaged tooling from the borehole. When damaged equipment falls into the wellbore the “fish” or “junk” must be removed as quickly as possible to minimise down time. Tasman’s wide range of fishing tools for the oil and gas industry include casing scrapers, junk baskets, overshots, fishing spears, fishing jars, fishing magnets and more. Each individual downhole fishing tool is precisely designed for a specific function and to retrieve a certain type of junk. Tasman’s wide range of fishing tools can assist with all your borehole retrieval needs. Take a look at our range below or contact Tasman’s friendly staff for more information.
