Course Overview

Painful experience has shown that even the most robust drilling programme can fail through incorrect implementation techniques.

Due to the increased challenges and numerous procedural revisions associated with high angle wells, educating personnel on how to identify issues before they become problems is crucial in delivering a successful deviated well.

Invest in yourself, your team and ultimately your results by attending Merlin ERD's Horizontal & High Angle Operations & Engineering Training Course.

What Will I Learn?
  • How to determine the maximum reach from your location
  • Key planning considerations to delivering trouble free wells
  • Root cause of problems encountered in high angle wells
  • Identifying minimum equipment specifications for ERD projects
  • What others are doing around the world to assure success
  • Latest tools and techniques used to reliably deliver ERD projects
  • How to minimise downtime due to 3rd party tools

ERD Quiz

Test your knowledge of ERD with these 10 multiple choice questions

First Name
Company Name
1. Downhole tool measurements indicate possible whirl vibration while drilling. Select the best course of action. (1 correct answer)
2. At what frequency should torque & drag measurements be taken while drilling the second well of the development project? (1 correct answer)
3. 9-⅝”, 43.5, L-80, VAM TOP Casing is selectively floated on a high angle well (12-1/4” HS 24,000 ft / 7,300 m MD; 15,000ft / 4,573 m TVD). 11.0 ppg / 1.32 s.g. oil based mud, 73° Inclination. Which of the risks below would be of most concern whilst running the casing? (1 correct answer)
4. What part of the "S-shape" well normally has the highest rate of casing wear? (1 correct answer)
5. At what inclination is the hole hardest to clean? (1 correct answer)
6. A 12-1/4" hole section of an ERD well (75° inclination) is drilled with 1,200 GPM / 4,550 LPM & 160 RPM. There is a constant flow of cuttings on the shakers and torque & drag data follow the expected trend. What is the average cuttings bed height in the tangent section of the well? (1 correct answer)
7. On an ERD well, after the 12-1/4” hole section was drilled to TD (20,000 ft / 6,000 m), a clean-up cycle of 5 x bottoms up was performed at 1,000 GPM (3,770 LPM) and 80 RPM. Shakers are clean of material. Based on the clean-up parameters used can you assume the hole is clean for safe tripping?
(1 correct answer)
8. What is the main downside of drill pipe sinusoidal buckling? (1 correct answer)
9. After drilling a 12-1/4” hole section on an ERD well, 4 x bottoms up are circulated at TD with parameters above hole cleaning thresholds. After the 2nd bottoms up the shaker hand reported the decrease in cuttings to a background level, which remained the same for the rest of circulation. Is it safe to start pulling out of hole on elevators? (1 correct answer)
10. In the middle of the trip out of the hole, having successfully backreamed a problematic 650ft / 200m interval, what is the next step? (1 correct answer)
