An overshot tool is a kind of oil tools designed for drilling the petroleum oil fields . These down hole equipments are used for the fishing operation to fit into place the outside plane of a tool or a pipe. Fishing refers to the act or operation in which the specific tools are lowered down the hole on the drill string in order to get back a fish. Here the fish does not refer to the biological body but it is anything that is lost or dropped down the hole.
Most times , there are few objects that get stuck in the bore of the well and then require removal with the help of the overshot tools. This object called the fish is gripped by the grapple or any instrument of the similar mechanism which is situated on the overshot. This function of the overshot allows the appliance of the tensile force and the grating action.
The overshot tools are also geared with the release system that is put so that it may enable the overshot to be detached and get back in the case when it is not possible to remove the fish. Such incidents of losing the fish inside the bore or get it stuck can result in great loss to the man and machinery and thus should be taken care of.
At times, we don’t emphasize enough how essential it is to have the proper quality equipment for serious jobs. Purchasing cheaply manufactured oil tools can results in problems, even catastrophes, as the BP oil spill in the gulf of Mexico can attest.
With the help of these overshot tools, this problem is solved to a great extent.
Now we have establised the importance of quality and great tools. Bettermachines is a manufacturer of such tools, in Snyder Texas. These tools are made up of corrosion resistant and strong material to withstand the tensile force exerted at the time of removing or getting back the fish. Thus by making use of such oil tools in the process of drilling the oil fields, we can increase the production and reduce the losses to a great extent.
