How does washout affect the TOC calculation?

Washout increases the effective hole diameter, which increases the annular volume and results in a different `calculate_toc_depth` result compared to a perfect cylinder.

Can I account for cement lost to the formation?

Yes, the `calculate_toc_depth` tool includes an optional parameter for losses to adjust the effective slurry volume.

What is displacement volume?

Displacement volume is the amount of fluid needed to push the cement to its target depth, which can be calculated using `calculate_displacement_requirements`.

This MCP server provides specialized engineering tools for wellbore operations. It allows AI agents to determine the Top of Cement (TOC) depth by accounting for hole size, casing diameter, slurry volume, washout, and formation losses. Users can also calculate displacement requirements to move cement to target depths, determine bottom fill volumes, and compute annular capacity per unit length.
