Fracing Casing Failure Mechanisms and Modeling
All
Casing failure is a serious issue in our industry. We approach the start of a New Year, new technology is available and can help us design better wells and components. In 2019 imagine an accurate erosion / wireline damage model that could be used real time to assess tubular health.
LaserStream's BEMIS(TM) systems have been used to help analyze internal damage in several high profile tubular failures, including the Aliso Canyon Blowout. Think of it as a 5000 arm laser caliper taking millions of high precision measurements on the inside of your tubular asset (or LIDAR for the inside of Pipe)
Some uses of the technique in assessing your tubular failures.
- Measure ovality accurately
- Measure erosion. See erosion signature coming in and out of connections
- Measure wireline cuts
- Measure connection mismatch and pin to box interface
- Measure ERW seam/trim end to end
Using this technique. Wireline cut is being measured in wells from multiple basins and applications. The damage is only getting worse as we pull more tension in our systems and run more descents. We have manufacturing irregularities, then wireline cut, then frac, then corrode, CT keyseat (REPEAT). Corrosion is happening on top of erosion and mechanical damage. It's a multiple factor mechanism. Laser Profilometry can efficiently resolve these damage mechanisms to provide a digital record that can be immediately dropped into FEA models or CFD models.
