P&A / Decommissioning
Plug and Abandonment (P&A) in the oil and gas industry refers to the process of permanently sealing and abandoning a well that is no longer productive or economically viable. This operation is crucial to prevent any potential environmental impact, such as groundwater contamination and greenhouse gas emissions.
ScanWell’s advanced technology can provide critical diagnostic information during various stages of P&A activities, that is traditionally unavailable that can both reduce risk of failure, and also reduce expensive rig-time due to reduced uncertainties.
Acoustic TOC Determination
ScanWell’s EzScan System and Acoustic Software empower operators to locate the Top of Cement (TOC) and cement plug depths without intervention. This reduces uncertainty, minimizes rig time, and cuts costs, ensuring efficient and successful P&A operations.

XLOT’s (tbc) for formation stress evaluation
The Extended Leak-Off Test (XLOT) measures stress in wells to predict stability. It involves multiple cycles and longer data collection to determine fracture propagation pressure (FPP). ScanWell uses ATEX-rated equipment for rigless XLOT testing, aiding in stability, fracturing, and sand production evaluations.
