In oilfield workover operations, a base beam serves as a crucial stabilization system, acting as an alternative to ground anchors, particularly in challenging terrains, and ensuring the rig’s stability during operations.
Here’s a more detailed explanation of its purpose and function:
Purpose:
- Stabilization: Base beams provide a stable foundation for well service rigs, especially in areas where traditional ground anchors are impractical or impossible to use (e.g., shallow soils, rugged terrain, swampy areas, permafrost, or shallow bedrock).
- Alternative to Ground Anchors: They are a viable alternative to ground anchors, allowing for operations in a wider range of soil conditions and terrains.
- Enhanced Stability: Base beams enhance stability, particularly near larger cellars on multiwall pad configurations.
- Smaller Footprint: They contribute to a smaller footprint of a deployed well service rig.
- Rig Up/Rig Down Times: Base beams can help decrease rig up and rig down times.
- Safety and Efficiency: They are designed for safe, efficient, and economical operation.
Function:
- Rig Stabilization:
Base beams are designed to withstand the rigorous stresses of the oilfield and provide a stable platform for the well service rig during operations. - Guying Solutions:
They are designed to meet the requirements of API RP 4G 14.3, which outlines best practices for well service rig stabilization. - Mobile Rig Operations:
They are suitable for use with mobile rigs, allowing for flexibility in well servicing operations. - Blow Out Prevention Equipment:
Base beams may be equipped with a stump or pedestal upon which Blow Out Prevention Equipment (BOPE) can be stored and transported. - Transportability:
They are designed to be transported on truck trailers over long distances. - Engineering Standards:
Base beams must be engineered to meet safety, performance, and fabrication optimization standards. - Industry Standard:
Base beams have served as a standard form of well service rig stabilization for over 20 years.
