Increasing drilling activities owing to the increased investments in oil and gas exploration and production activities is boosting the drilling jars market. The market is expected to grow during the forecast period as the drilling activities are expected to increase across the globe. Huge investments are made by oil and gas companies to explore and drill offshore deep water and ultra deep water reserves that are unexplored. The shift from onshore to deep offshore reserves is due to depleting onshore reserves and attractive rate of returns from abundant offshore deep water reserves.
Drilling jar is an important component of drilling string. The success of a cable tool drilling very much depends on drilling jars. Drilling jars are used to free the drill string into the well bore. Drilling jars have been improved over the time to provide better results and reliability for drilling operations. Drilling jars deliver a heavy impact load to release the drilling string. The impact provided by drilling jars is known as “jarring effect”. Downhole jars are a part of drilling string and remains in the bore hole as long as the drill bit works. Hence they should be capable to withstand the extreme downhole temperature and pressure. The drilling should be able to survive the vibrational and rotator loading associated with drilling. The drilling jars are designed to reset by simple string manipulation and are capable of multiple firing or recovery operations.
While planning a drilling program, the possibility of sticking a drill string is taken into account and drilling jar is added to the bottom hole assembly to deal with this problem. Drilling jar creates an impulse force to jar free a drill string. The impulse force is created by converting strain energy into kinetic energy. Drilling jars are used in bottom hole assembly for drilling a vertical as well as horizontal wells.
On the basis of type, the drilling jars market can be segmented into hydraulic drilling jars, mechanical drilling jars, and hydraulic-mechanical jars. The hydraulic and mechanical jars are available in single unit and two unit jars that offer a combined mechanical and hydraulic action. The drilling jars also provide a two way action that enables the operator to work the drilling jar both downward and upward. The mechanical latch ensures that the jar will not accidently fire while making connections or tripping. The upwards hydraulic operation utilizes pipe stretch to assist in jarring performance and use the drill collar weight to aid in the jar impact. The jar is fired downward by overcoming the downward lock setting mechanically.
Increasing drilling activities to meet rising energy demand is acting as a driving factor for the drilling jar market. Accelerated efforts to produce unconventional energy from shale gas have resulted in drilling large number of wells in North America. Abundant shale gas reserves and deep end ultra deep water oil and gas reserves provide a huge opportunity to the drilling jars market.
