Application

An established Permian operator struggled to determine the cause of a parted Electronic Submersible Pump (ESP). After a lead impression block failed to return actionable information, the operator attempted to push the ESP downwell but was unable to move it. The operator turned to DarkVision for the information they needed to determine the correct course of action.

Results

Darkvision’s HADES-F™ scanned the well at a depth of 5070 ft, where it identified a severe casing collapse. The 3D images and measurements provided by DarkVision enabled the operator to develop and execute a remedial action plan. The operator ran a casing swage to push the casing back to its nominal internal diameter.

High-resolution volumetric data from DarkVision enabled the operator to determine that fishing the ESP would not be possible, and pushing it to the toe of the well was the fastest and most cost-effective means of regaining well access. HADES-F™ opens new paths to solving complex well obstruction and restriction problems.

By combining ultra-high-resolution acoustic imaging with steerable 4-degree-of-freedom robotics, HADES-F™ can scan around restrictions and obstructions, seeing key details which would be blocked from view by traditional side and forward-facing tools. Real-time results enable rapid decision-making right at the wellhead.

Operators face growing pressure to minimize non-productive time and control costs. The flexibility of HADES-F™ helps them achieve these goals. It can be deployed on widely available e-coil and e-line conveyance and does not require time consuming and costly wellbore cleanout or fluid swapping. The high-resolution 3D data delivered by DarkVision enables operators to make informed decisions for remedial action on complex well obstruction and integrity issues.

Clear, unambiguous results from HADES-F™ eliminate risk and minimize non productive time.
