Varel's suite of software tools is designed to seamlessly move from the definition of the drilling challenge to the right drill bit solution. These software modules have been carefully developed to move complex data from one stage to the next without the need for keyed data re-entry or translation. All critical data is carried foward step to step.
Performance benchmarking and bit record review proceeds to analysis of rock properties from customer log data. When coupled with the well plan this analysis quantifies the drilling challenge.
Step 2: SPOT
SPOT cutting structure design is employed to create a cutting structure that will meet the drilling challenge. The SPOT mathematical model is used to perform a drilling and wear simulation to verify it corresponds with the GeoScience findings.
Step 2A: Existing Bit Design
If appropriate, an existing bit design is recommended to meet the requirements of the GeoScience analysis.
Step 3: Pro-Engineer CAD
Pro-Engineer CAD design system, custom developed for drill bit body design, is used to design a complete bit 3D model incorporating the SPOT cutting structure.
Step 4: Computational Fluid Dynamics
CFD analysis is employed to optimize the fluid flow characteristics of the CAD model. The model aids in the analysis of the cooling and cleaning characteristics of the 3D model.
Step 5: Pro-Engineer CAM
Completed bit design is programmed for complete CNC manufacturing process to produce the bit.
Step 6: Bit Run and GeoScience Post Run Analysis
GeoScience is once again used to analyze the bit's performance versus the initial plan and prognosis. If needed the initial GeoScience analysis is recalibrated prior to the start of a new iteration of bit design.
