This year he completed what is believed to be the first ever fracture stimulation procedure in Turkey: injecting a mixture of water and sand at high pressure down the wells to break up rock and release gas.
About 25, 000 wells a year are being fracked, a process in which water, chemicals and sand are injected at high pressure underground to release trapped natural gas.
As the drill progresses through the rock and sand below the seabed, the pressure of the mud in the drill string must be kept within a limited range.
It meets the highest standards of resistance to dust, sand, shock, vibrations, low pressure, high and low temperature, rain and long-term moisture.
Fracking uses high-pressure mixtures of water, sand or gravel and chemicals to crack rock formations and release oil and natural gas deep underground.
It extracts oil from the ground using a method called fracking - pumping down a mixture of sand, water and chemicals at high pressure.
They had been protesting at a site in Hesketh Bank operated by energy firm Cuadrilla which was given a licence in 2008 to extract gas by pumping water, sand and chemicals into shale rock at pressure.

The drilling technique, which uses sand, water and chemicals under high pressure to extract oil and natural gas from rock formations, has helped Eagle Ford oil production grow by 184% last year compared with 2011, according to the Railroad Commission of Texas, which regulates the state's oil and gas exploration and production.
Hydraulic fracturing pumps many thousands of gallons of mainly water and sand, with a few chemicals, at high pressure into tight gas-bearing shale deposits (hardened muds), creating cracks that allow gas to flow back up the well to the surface ( Shale Shock).
Under the process of fracking, oil or gas is extracted from shale rock by pumping a mixture of sand, water and chemicals into the rock at high pressure.
In fracking, a mixture of water, sand and some chemicals is pumped into a well under high pressure to force the gas from the rock.
Carbo Ceramics ( CRR - news - people )(CRR, 73) , a Houston firm that makes various forms of "proppant, " particles (sand or a synthetic substitute) injected along with the fracking fluid to keep the fissures propped open after the pressure is withdrawn.
