Downhole Tools: Effective Equipment to Extract Untapped Oil from Oil Wells


What are Downhole Tools?
Downhole tools are the equipment that are used in numerous operations including the production of oil and gas, well interventions, well completions and well drilling. To perform these activities, a number of downhole tools like drilling jars, roller centralizers, shock tools, drag friction, tubular tools, drill pipes, and fishing tools are used. Other than this, these types of tools are also used in bottom hole assembly for well completions as well as workover operations. These are mostly useful for processes that are conducted during harsh temperatures and pressure conditions.
Downhole tools are used for bringing down the costs associated with oil recovery-activities and also making sure that there is a surge in oil production. Apart from this, these tools find use in a variety of operations such as casing, fishing, well-bottom communication, cementing, logging, drilling, fracturing, and well measurement.

In summary, downhole tools are a type of oilfield equipment, used for well drilling, workover activity combined with well intervention. Massive amount of oil is left untapped underneath the surface; wherein downhole tools offer a host of benefits such as elevating the production levels from the oil wells. In addition, these tools also help maintain the flow from a reservoir. For completing these kinds of activities, a broad range of downhole tools like drag friction, roller centralizers, fishing tools, shock tools, tubular tools, drill pipes, and drilling jars are used.

Types of Downhole Tools
Reamer
A reamer refers to a type of rotary cutting tool that is used in the process of metalworking and also for drilling to expand the size of the holes. Reams gives a finish of top quality as well as straightness when the operation is completed.
Drill String
A drill string can be defined as a string of a drill pipe that is located on a rig. This rig is used for transmitting the torque along with drilling fluids to the drill bit.
Tubular Jars
Tubular jars are a special tool used in slickline operations along a slickline, which is either warped back or stretched. The tubular jar generally finds use in fishing operations, where there re high chances of debris or other things that can clog the wellbore.
Slickline Tools
Slickline finds widespread use in production tubing. It can be described as a single strand of wire that helps run the tools into a wellbore for various purposes. Several slickline tools that are used for conducting various functions include stems, rope sockets, running, pulling tools and jars.


Region-Based Demand for Downhole Tools
A number of operators in the Middle East as well as North Africa are more active in drilling operations, with the aim of implementing numerous latest downhole tools technologies. International companies are striving to explore new horizons to gain from the increasing supply of crude oil in these regions. To illustrate, mounting demand for advanced downhole technologies has prompted Halliburton in the Middle East to create a strong name in project management and also lower down the cost of drilling wells.
North America remains a substantial region, making massive demand for downhole tools. The highest demand for downhole tools originates from the United States (U.S.), given the high concentration of a large number of oil field services vendors coupled with the increasing use of advanced technologies.
