ABSTRACT
A choke bean used in an oil–gas field has catastrophically failed during operation. It is shown that that the damage has been caused by leakage of the corrosive and abrasive drilling fluid. The choke bean adapter made of carbon steel has been corroded and embrittled by hydrogen ingress leading to its fracture in the presence of stresses created by the pressure of accumulated fluid at the bottom section. On the other hand, the choke corner body made of stainless steel has been damaged by abrasive wear of its outer surface.
4. Conclusion
It is concluded from the present study that the components of the choke have been damaged by leakage of the abrasive and corrosive drilling fluid. Most evidence point out that the beam adapter has been damaged by corrosion and hydrogen embrittlement in the presence of the stresses created by the fluid pressure eventually leading its fracture along the longitudinal direction. On the other had, the abrasive fluid traveling at high speed and bypassing the normal passage through the internal surface of the choke corner body has lead to abrasive wear of the outer unprotected surface.
