Problem and Challenges
- Sustained casing pressure observed in multiple wells
- Uncertainty regarding the leak rate and whether it falls within API acceptance limits
- Unknown liquid level in the annulus
Solution
- Annulus Pressure Diagnostics (APD)
- Liquid Level/Echometer Survey (SBHP)
- Direct flow measurement of liquid and gas at the surface
Results
- Obtained comprehensive information on annular integrity status for each well, referenced against API standards, enabling the operator to make informed decisions for rectifying or managing each issue
- Provided SBHP data (without intervention), comparable to conventional SBHP logging data acquisition
