When poor integrity leads to blowout A case study reviews well integrity in ageing assets and the remediation efforts required in the aftermath of a land-based well blowout in the Middle East.
Language: Inglés Publication details: ene. 2021Description: [c.a.] 4 pOnline resources: In: E & P Summary: There are a variety of triggers that can lead to surface and underground blowouts on oil and gas wells. Drilling and workover operations that exhibit a compromised hydrostatic barrier can permit formation fluids to come to surface. Additionally, a surface barrier may fail on a production well. In both cases, these events could lead to a surface blowout. On the other hand, underground blowouts can happen if there is formation flow from a high-pressure reservoir to a formation with lower integrity. This is typically the result of some type of downhole failure. A particularly severe event can occur if loss of well control barriers follows. The crucial factor in the ability to cap a surface blowout, or reenter and concentrically kill an underground blowout, is the well control specialist’s ability to gain access to the wellhead.| Current library | Status | Barcode | |
