Overpull calculation
WebIf you don’t have high confidence in your estimate, err on the side of caution and do the calc as if the string were in air. Now subtract buoyant string weight from your 80% tensile rating and you’ll have your max overpull at surface. TLDR: Available overpull = Yield - buoyant string weight Wisconsinwonder • 1 yr. ago WebLag time calculation. Light weight spot fill to balance formation pressure. Loss of hydrostatic pressure due to filling water into annulus in case of lost return. Margin of over pull. Maximum ROP before fracturing formation. Pipe elongation due to temperature. Pressure required to brake circulation. Pump out.
