ERD TRAINING

Covering the fundamentals of hole cleaning and drilling load generation through to advanced engineering subjects, our training will help you and your team drill further, faster, more efficiently.

ERD SOFTWARE

We’ve designed TDH to be as quick and simple to learn as possible yet offering advanced features for those that need them. If you do not run torque, drag and hydraulics models every day, the last thing you need to do is relearn the software each time you use it.

Offset Well Review

The offset well review is where it all starts. It’s the foundation for reliable well delivery later on down the track. The objective, supportable assumptions which are validated through this exercise create a firm base for which to layer on the complexities involved in extended reach, high angle and complex wells. Reviewing 3 to 5 wells provides the most reliable data to verify friction factors and subsurface modelling assumptions, ensuring that subsequent conceptual well designs and feasibility studies are grounded in fact, with the lowest possible uncertainty.

Feasibility Study

Accurately determine what it will take to reach a prospect from existing infrastructure. Define a dependable drilling radius for field development planning and/or to identify minimum rig specifications for your challenging wells. These are a few of the factors that a detailed feasibility study allows the drilling manager to assess. Merlin’s work is based on our knowledge of what’s possible, gained from working on the industry’s most challenging wells in over 40 countries.

Problem Review

Fresh eyes and a lack of preconceived ideas is what Merlin brings to a problem review. Our focus on challenging extended reach wells enables us to provide a unique view on wells which have experienced difficulties during the construction process. By assessing drilling operations against an ERD methodology, we are able to identify areas where a revision to engineering or operational practices will yield performance improvements and a reduction in unplanned events.

Detailed Well Design

Systematically building on the offset review and feasibility study outputs, the detailed well design is the last opportunity to make sure that critical risks are engineered out of the well architecture, rather than controlled through process. Merlin can undertake the detailed design work in its entirety or support in specific areas – whatever is necessary to create the greatest opportunity to assure drilling success. Specifically, we can support with trajectory design, targets, drill string and BHA design, casing scheme options, drilling fluid specification and properties, wellbore stability and casing wear assessments as well as any of the other routine and not so routine considerations which feed into a complex well design.

Performance Optimisation

Successful, reliable well delivery is the first challenge to be overcome on many projects. Once that’s in the bag, how do we ensure we keep moving up the performance learning curve? Keeping the bit on bottom and drilling efficiently whilst minimizing energy lost through vibration, understanding system limits to optimize tripping speeds for drill pipe and casing, proactively managing planning and programming activities to gather and integrate lessons learned – all of these activities will allow us to drill further, faster, more efficiently, more often. Merlin’s integrated performance optimisation processes can facilitate this process quickly and efficiently.
