What is Schlumberger SandCADE Software?
Schlumberger SandCADE is an engineering software application designed to assist in the design and simulation of sand-control completion strategies, with a particular focus on gravel-packing and frac-packing operations. It provides a comprehensive environment for engineers to model various aspects of these treatments, aiming to optimize designs and predict performance.
Core Capabilities for Sand Control and Gravel Packing
SandCADE integrates various sand-control completion elements into a unified platform to facilitate the design of optimal gravel-pack strategies. Key features include:
- Gravel-Packing Process Simulation: The software simulates gravel-packing processes, enabling engineers to conduct sensitivity analyses. This includes evaluating variables such as completion intervals, carrier fluids, gravel sizes and concentrations, pump rates, downhole fluid leakoff, and surface returns. This allows for detailed understanding of how different parameters impact the operation.
- Integrated Design Environment: It combines all necessary components for sand-control completion design, streamlining the workflow from initial concept to detailed planning.
Advanced Frac-Pack Design and Simulation
For frac-packing treatments, Schlumberger SandCADE offers advanced simulation capabilities:
- Coupled Hydraulic Fracturing and Wellbore Simulation: SandCADE couples a hydraulic-fracturing simulator with a wellbore simulator. The hydraulic-fracturing component models fracture geometry, proppant distribution, and 2D fluid flow within the fracture. This is integrated with a wellbore simulator that models fluid and slurry flow within the screen-casing annulus and Alternate Path shunt tubes, providing a comprehensive view of the frac-packing process.
- Multilayer Fracturing Simulation: A specialized feature allows for the simulation of simultaneous fracturing of multiple layers. This capability supports modeling scenarios both with and without shunt tubes, aiming to achieve more uniform fracture lengths and widths across a completion interval. This is crucial for optimizing production across heterogeneous formations.
Why Choose SandCADE: A Differentiated Approach to Frac-Packing
An independent SPE technical paper has highlighted a key differentiator for Schlumberger SandCADE: it is described as the only commercially available software that accounts for completion and gravel-packing equipment when modeling frac-packing treatments. This specific capability provides engineers with a more accurate and comprehensive understanding of how mechanical completion components interact with the hydraulic fracturing and gravel-packing processes, leading to more reliable designs.
Understanding the Impact of Equipment Integration
The ability to integrate completion and gravel-packing equipment into frac-pack models means that simulations can more realistically represent downhole conditions and interactions. This detailed modeling helps engineers to:
- Predict the impact of specific hardware on slurry placement and gravel distribution.
- Refine treatment designs to avoid potential complications related to equipment presence.
- Optimize equipment selection based on simulation outcomes for various scenarios.
