Under Vehicle Search Mirror offers a wide field of view and the hinged handles lowered to ground level for maximum under vehicle penetration. The under vehicle search mirror are portable inspection mirrors that are invaluable for looking into hard to see places in high security areas. Under vehicle search mirror are used by enforcement agencies, engineering, building maintenance, armed services and security guards.
Underbalanced drilling operations reduce the hydrostatic pressure of the drilling fluid column so that the pressure in the wellbore is less than the formation pressure. It is defined as the practice of drilling a well with the wellbore fluid gradient less than the natural formation gradient. It differs from conventional drilling in that the bottomhole circulating pressure is lower than the formation pressure, thereby permitting the well to flow while drilling proceeds. Underbalanced drilling technology is a valuable method for minimizing formation invasion related problems. Most of the underbalanced drilling applications are conducted through the use of coiled tubing systems.
Underbalanced drilling is defined as drilling operations where the drilling fluid pressure in the borehole is less than the pore pressure in the formation rock in the open-hole section. The light fluids used in underbalanced drilling are usually air, gas, foam and aerated water. Unaerated oil, water and weighed mud are used for underbalanced drilling in areas where formation pore pressure gradients are higher than the hydrostatic pressure gradient of water. Underbalanced drilling technology is an integrated technology, resulting from merging traditional air and gas-drilling techniques with aerated & foam drilling method. These drilling avoid overbalanced pressure to the rock below the drill bit. Underbalanced drilling is an effective means of minimizing lost circulation problems in drilling naturally fractured petroleum reservoirs and pressure-depleted reservoirs.
Undercoating Pumps are used for spraying of adhesives and roof coatings application. It has double-toggle balances pressure on air valve trip mechanism to prevent binding or stalling. The corrosion-resistant chrome finish on piston rods alleviates packing wear.
