Wireline Fishing Spear


Many problems can occur which decrease the efficiency of a drilling operation and increase drilling costs. A substantial amount of time and money can be spent 'fishing' for wireline in the well-bore during a drilling operation. Wireline is used to lower measuring devices, called tools, into the hole which look at properties of the formations and the well-bore itself. When it breaks it can be quite difficult to bring the remaining wireline and tools back to surface with a wireline fishing spear. This instrument, while effective, can be difficult to attach property to the wireline. The re-designed wireline fishing tool will incorporate ideas to circumvent the problem of hooking the wireline and use mechanical design skills and some fluid flow and pressure analysis.
