| Drilling hydraulics become increasingly complex in today’s more prevalent 3D long-reach wells. HYDMOD is a comprehensive drilling hydraulics program that covers almost all aspects of hydraulics, including pressure drop and flow regime, surge and swab, equivalent circulation density (ECD), nozzle selection, hole-cleaning efficiency, and volumetric displacement. Results are displayed effectively for quick and easy analysis.
HYDMOD now includes correlations for calculating pressure drops in slim annuli. ECD's in slim-hole wells can be adjusted by varying flow rate ("Dynamic Kill") since pressure losses in the annulus are a
significant proportion of overall pressure drop.

Detailed hydraulics analysis results are displayed and readily accessed.
Clearly displays relationships between hydrostatic, pore, fracture, drill-pipe and annular pressures with depth.
The Sensitivity utility helps you quickly gauge the impact of variations in key parameters.
The Dynamic Kill utility is very useful for comparing the results of changes in flow rate, mud weight, and pipe rotation on bottom-hole ECD in slim holes. |
