OEE Calculation: Definitions, Formulas, and Examples | OEE
OEE can also be calculated using the simple calculation. Formula: (Good Count × Ideal Cycle Time) / Planned Production Time. Example: (18,848 widgets × 1.0 seconds) / (420 minutes × 60 seconds) = 0.7479 (74.79%) The result is the same in both cases. The OEE for this shift is 74.79%. Download Free OEE Tools.

Introduction. Casing and cementing are essential to drilling oil and gas wells. Lining a hole with casing keeps it from caving in after it is drilled, sealing the wellbore from encroaching fluids and gasses. Cementing the casing in place ataches it firmly to the wellbore wall and stabilizes the hole.

Common Well Cementing Problems and Solutions
Solving a gas migration problem is typically dificult and costly. To determine the leak path, cement evaluation logs can be used. The leak path is then perforated, a cement squeeze is performed, and the well is checked to see if the gas migration problem has been resolved. Gas migration paths are typically quite small.
