It is a drilling technique used to reduce the chip holding pressure when it be forced and make a difficulties to remove a part of rock by bit through rotary carbon steel teeth bit and by weight on bit , it used the UBD to make a secondary annulus by using another casing like tie back to divided the annulus to two part to relief the hydrostatic column drilling fluid pressuer and that will reduce the chip holding ppresseure and will be traet even the kicks without breaking the drilling operation to treat the kick off well
their drilling samples
The data collected by the drilling ship Glomar Challenger confirmed continental drift.
i dont have any idea what it is it makes no sense
To investigate the evolution of ocean basins by core drilling of ocean sediments and underlying oceanic crust.
MWD is measurement while drilling. It records values like direction, inclination, toolface etc, which all are values needed to achieve a successful drilling. LWD is logging while drilling. It records logs (which generally are run by wireline, after drilling). Most common being gamma and resistivity logs. It gives us real time log data which helps to geosteer. In BHA, the arrangement is like... [ BIT - RSS* - MWD* - LWD* ] (* - optional)
I believe you mean what are the risks in drilling a hole (oil well) underbalanced. The result can be a blowout and oil well fire. Drillers must keep the right mud weight in order to hold back gas that is trying to come to the surface.
They are drilling into the earth's crust. Geothermal energy comes from heat under the surface of the earth.
The fact that oil is under ground.
Diamond drilling occurs in primarily under development countries. Many countries in Africa such as Botswana, Liberia, and South Africa all use diamond drilling in their mining industry.
Off-shore drilling is the search for and collection of oil lying in the ground under the relatively shallow waters of the continental shelf.
Drilling for oil on land is usually cheaper than drilling under the seabed due to several factors. On land, the infrastructure costs are lower, as there is no need for specialized equipment, platforms, or pipelines. Additionally, the depth and pressure of the reservoirs under the seabed can be much higher, requiring more complex and expensive drilling techniques. The harsh marine environment also leads to increased operational and maintenance costs for offshore drilling.
In Army terminology, ROC Drill is a Rehearsal of Concept.
No. Generally they are pulled by tugboats.

Onshore oil is a nickname for oil that is obtained through oil drilling that is completely on land, as opposed to offshore oil, which is collected from drilling under the seafloor with floating oil rigs.
In offshore drilling, rigs mine oil from under the ocean floor. The oil is then carried to the surface via large pipes, so that it can be shipped away and refined into petroleum products.
