But with the technological developments over the years, the cost involved in offshore oil and gas projects has come down. Higher capital investments are involved in offshore projects and such projects receive returns on investments over an extended duration. Recent industry analysis indicates that with increasing investments in offshore projects the global market of directional drilling will experience growth. The telecommunication companies have also been using these services for the installation of fiber-optic cables.ДЄ Brief Overview of Global Market for Directional Drilling Services Directional drilling services are extremely exacting for this application category.Дirectional drilling services are employed extensively for the placement of pipelines that cross beneath rivers. Following this, mud and water are pumped into the relief well to kill the wild one. In relief well drilling, an uncontrolled or wild well is intersected near its source. The possibility of drilling problems increases with drilling a vertical well through a salt dome. Production of formations can be found under the hard, overhanging salt dome caps. Hole conditions may also be affected because of formation pressures along fault planes. With respect to unstable areas, a wellbore drilled through a fault zone could be exposed to risk due to the probability of movement or slippage along the fault. For this, the wellbore may be sidetracked perpendicular or parallel to the fault for enhanced production. It becomes very difficult to drill a vertical well through a steeply inclined fault plane to reach an underlying hydrocarbon-bearing formation.

If a certain direction is critical in locating an anticipated producing formation, oriented sidetrack is required. With a blind sidetrack, drilling around obstructions, such as a lost string of pipe, is usually accomplished.

This technique may be employed either to drill around obstructions or to reposition the bottom of the wellbore for geological reasons. This also finds application in multiple production zones which are adjacent to a fault plane or beneath a salt dome. Directional drilling happens to be the most economical approach for a multiple completion in cases in which the bed dips of the producing formations are designed in such manner. Intersecting multiple targets with a single wellbore is a highly cost-effective way of delivering high production rates. Directional drilling services are required for applications like this where wells with вЂextended-reachвЂ™ are most commonly drilled. It is the location of a producing formation that dictates the remote rig location and directional-well profile. When a well is inaccessible with normal vertical-drilling practices, the technique of directional drilling is employed to reach a producing zone. Consequently, the demand for directional drilling services is constantly increasing. Directional drilling technique has immensely contributed in bringing down the costs and the ecological impact of this application. With respect to field developments, specifically offshore and in the Arctic, it is important to drill an optimum number of wells from a single platform or artificial island.
