Drone-Based Monitoring of Energy Infrastructure Sites. Chelpipe.avia Project

Drone-Based Monitoring of Energy Infrastructure Sites

Скачать каталог

Chelpiper 75 is a drone enabling panoramic and vertical still and video aerial photography and other similar functions. Its modular design allows to quickly replace various drone payloads and modify the onboard equipment configurations.

Chelpiper 75 drone's technical characteristics make it a highly efficient unmanned system for protection of oil and gas pipelines.

With air range of at least 360 km, operating altitude 50 ÷ 500 m and flying time of more than 4 hours, the drone is stable and docile enough to be used in challenging weather conditions. The pulling propeller design perfectly suits the intended application and ensures personnel safety.

The extra onboard volume inside the wings allows the drone to carry a broad range of instrumentation. The drone's onboard instrumentation and Automatic Control System enable video and photo data recording while registering multiple service parameters (coordinates, altitude, frame number, etc.), which greatly facilitates post-processing and, most importantly, automates the stitching of frames and helps determine target coordinates. The drone carries photo and video cameras, a thermal imager and a gyrostabilized television camera.

Complex analysis of data streamed by the drone allows to:

  1. Monitor oil spills
  2. Locate illegal taps 
  3. Locate pipeline sections laid at non-standard depths
  4. Monitor new objects within the protected zone 
  5. Monitor and identify moving objects within the protected zone, even during the night
  6. Quickly receive video and photo data from hard to reach locations 
  7. Evaluate forest invasion to predict deforestation needs along the pipeline
  8. Evaluate the speed and quality of repair and construction operations
  9. Evaluate pipeline condition at ground-to-water transitions 
  10. Perform large area still and video photography 
  11. Create photomaps
  12. Perform multiband photography 
  13. Perform industrial and environmental monitoring 
  14. Perform land inventory and status assessment work 
  15. Perform cadastral work

Investigation Operations

Professionals in Rimera Group's Well Logging Division command a system of successful techniques for examining wells and managing drilling emergencies.


Cased Well Investigations in the Course of Construction

Скачать каталог
Our set of well-logging operations insures that geological investigation objectives are achieved by lowering radioactive and acoustic logging tools three times.
  • cross-cut lithological layering and subsequent correlation;
  • reservoir quality discrimination;
  • assess reservoir porosity, clayiness, and permeability;
  • assess reservoir saturation characteristics;
  • identify oil-water, gas-oil, and gas-water contacts and subsequently tie perforation intervals to these;
  • check casing condition using acoustic cement bond logging, flaw detection, temperature logging, gamma flaw detection, gamma thickness measurements, electromagnetic collar logging, electromagnetic flaw detection, acoustic video cable logging, and mechanical pipe profile logging.

In the course of the operations, we perform MWD, log drilling fluid characteristics, such as content of hydrocarbons and other fluids flowing from tapped reservoirs; collect and perform quick analysis of sludge and core.

Open Hole Investigations

Скачать каталог
The investigations are aimed at:
  • lithological layering of cross-cut using electric logging techniques;
  • identify reservoirs;
  • assess reservoir saturation characteristics. Rocks that comprise geological section have different specific resistance, depending on their lithological composition and reservoir saturation characteristics.
  • assess reservoir porosity and permeability.

Perforation operations having various applications and performed inside deep wells using powders, high explosives and other explosives. Blasting helps eliminate accidents, restore circulation, back off, shake, break or cut drillstrings, break for subsequent removal, or in some cases, remove metal objects left inside the well due to emergency, prevent sticking, etc.

Perforation (Cable and Pipes)
