What is your challange?

  • Corrosion 
    (of tubing and other wellbore assembly elements)
  • Fishing
    (of dropped and accidentally lost downhole tools)
  • Obstruction
    (of inflow into the well)
  • Valve Failure
    (of safety and regulatory/gaslift valves in the nipples or tubing-pockets)
  • Scale
    (barite and other chemical scaling in the borehole during oil production)
  • Leakage
    (due to isolation and fitting problems, or faulty seals)

Downhole fishing

Dropped objects (lost BHA, remnant cable, stuck valves, etc.) could cause significant issues with well integrity and affects production. Using Lead Impression Block (LIB) commonly called “confusion block” might cause further complications with increased operational cost and time, sometimes even without success.
Zerlux OptEye Downhole Camera inspection can perfectly visualize fish, determines the exact shape of fish top, define position of fish and all relevant information for planning further fishing operation that could reduce operational time and cost of fishing services with a more precise and successful action plan.

Corrosion

Corrosion of wellbore equipment is a major, frequent and global issue. Hundreds of thousands of older wells are affected by corrosion. Production containing corrosive fluids (CO2, H2S, etc.) often with high temperature and pressure causes issues related to well integrity. Operators responsible for managing well integrity issues understand the importance of up-to-date, exact and reliable information is essential for accurately diagnostic to have early identification and effective remedial actions.
Zerlux OptEye Downhole Cameras can reliably provide unique and clear view about downhole corrosion in wellbore to the operators.

Valve Failure

Proper, safe and reliable operation of any kind of downhole valves are essential, especially for downhole safety valves. Although valves are manufactured according to high quality standards, but valve failures are a very common observation and require urgent repair needs. The most trustable and convincing method to check the actual condition of valves is the visual inspection. Zerlux OptEye Downhole Cameras provide unique and clear visual information to the operators about the status and operability of downhole valves.

Well Leakage

Usually as a result of corrosion or mechanical failure (sometimes assembling mistakes) of wellbore hardware, small scale or significant leakages could appear inside the tubing having the potential to cause serious issues or in-well blow-out in some condition. The production flow could enter into tubing from the annulus space (or vice-versa) resulting an immediate impact on safety of well operation, health and environment. Using Zerlux OptEye Downhole Cameras this dangerous leakage can be easily locate and identified, finding the exact location, with shape and dimensions being precisely measured and visualized.

Hard Scaling in wellbore

Carbonate or special hard scale like barite becomes the second leading operational issue globally that causes production decline and immediate termination of production. According to case video downhole jewellery and perforation have been totally covered by barium hard scale while extreme downhole mineral precipitations are observed. Considering the actual conditions, Operators could decide action plan to make the well scale free again. Using Zerlux OptEye Downhole Cameras, precise identification of nature, size and location of hard scaling can be achieved to choose a cost-effective, most proper solution to apply.

Restrictions in flow

Downhole tubulars (tubings, casings) can limit the flow in a numerous way resulting production decline or immediate safety and environmental problems. Wellbore access could be completely barriered and with limited available information from well-depth about the actual downhole conditions operators might be unable to make proper decisions. Using Zerlux OptEye Downhole Cameras downhole barriers can be identified, and a cost-effective and most safe solution could be applied.
