ONGC Increases ROP by 40% to Save 15.7 Rig Days Using StingBlade Bit

Publication Date: 06/09/2017

Oil and Natural Gas Corporation Limited (ONGC) in India needed to drill a minimum of 300 m [980 ft] through a volcanic dike formation. In an offset well, the operator encountered high variation in unconfined compressive strength (UCS) throughout the section—in some places as high as 33,000 psi [228 MPa].

While drilling the offset well, nine bits were used to penetrate through 550 m [1,804 ft] of Mesozoic formation with an average ROP of 0.5 m/h [1.6 ft/h]. This resulted in high drilling costs. Moving forward, ONGC needed to cut costs in order to drill the deepest offshore HT well in the India and Bangladesh region.
