Services > Directional Drilling

DrillScan offers services in directional drilling based on our wide expertise and our in-house advanced software solutions. We offer support at various stages of the field/well development process. Our services can be delivered in-house or in the field and our team can rapidly provide solutions in emergencies.



Planning

At this stage of development, the aim is to define the best directional technique compatible with the project objectives. We provide a full BHA and bit design proposal for each section of future field development based on all today’s available technique analysis, including rotary, steerable motors, RSS and RWD systems. Uncertainties linked to formation effects, equipment characteristics, operating parameters, etc can be analyzed and integrated to quantify final risks & performances.



Pre-engineering

When planning a well, the drilling engineer may need to conduct a full BHA and bit design & optimization, or validate its direction driller (DD) proposal. We can rapidly integrate all operational context information to perform this pre-engineering analysis and provide primary & contingency BHA and bit design solutions.



Post-analysis

During the initial phases of a field development, the post-analysis of a BHA run is an important step that can speed up the learning process. We can explain underperformance and/or propose BHA and bit design changes in order to improve performance. Our analysis is based on the following steps:

  • Segmentation
    Runs are usually composed of multiple equilibrium curvatures due to BHA settings, formation or operating parameters changes. The run must be cut into segments where conditions remain constant before analysis.
  • Fitting
    Comparison between predicted and observed results is used to fit formation related parameters that present an significant uncertainty, improving the prediction reliability.
  • Recommendations
    Using the fitted parameters, a sensitivity analysis on the BHA and bit design is conducted to evaluate modifications that could improve performance.
