Specific Program Modules

Well Configuration Page

The core of the program—define your drill string, casing scheme, hole size, depth, and pump strokes.

Get instant calculations for:

• Pump pressure
• String volume
• Bottoms-up time
• Open-hole annular volume

Additional features:

• Graphical representation of system pressure losses (through drill string & annulus).
• Fluid velocity plots for all string components and annuli.
• Visual well trajectory plotting (with BHA components highlighted in orange).

Hydrostatic Pressure Evaluation (New in Version 13.0)

• Simulate pumping a fluid train (up to 5 fluids with user-defined weight & volume).
• Evaluate underbalance risks for up to four formations during the process.
• Supports vertical and deviated/horizontal wells (uses active survey data).
• Plots hydrostatic pressures and real-time fluid positions while pumping.
• New in Version 14.2: Hookload estimation plot added.

Ton-Miles & Hookload Calculations

• Calculates hookload and ton-miles for vertical, deviated, and horizontal wells.
• Uses industry-standard formulas from:
  • IADC Drilling Manual
  • Green Drilling Data Handbook

Hydraulics Page

• Automatically imports drill string & casing scheme data from Well Configuration.
• Calculates pressure losses across the entire well system, including:
  • Drill string components
  • BHA components (mud motor, MWD, LWD, Rotary Steerable Systems, etc.)
  • Bit nozzles
  • Up to 50 annuli sections
• Uses MI’s Drilling Fluids Manual for calculations.
• Supports Directional Drilling Contractor formulas (currently one contractor coded).

Single String Cementation

• Cement any string inside any previous casing and open hole size (as long as it's physically possible!)
• Easy pull-down selection for casing strings, cementing contractor, and additives.
• Customize and save your own cement chemicals & unit settings.

Balanced Cement Plug

• Define cement stinger, running string, casing scheme, and cement additives via pull-down menus.
• Enter key well data (plug length, top of plug, excess %, under-displacement, etc.)—the program does the rest.

Surveys Page

• Store up to five surveys with 1,000 survey stations each.
• Enter surveys, generate various plots, and interpolate data.
• The Active Survey Listing is automatically used in:
  • Hole Cleaning module
  • Horizontal Kill Sheet
  • Horizontal Well Control Simulator
• New in Version 11.1: 3D Virtual Reality survey viewing.

Hole Cleaning Evaluation (Experimental Feature)

• Calculates slip velocity, cuttings transport ratio, and cuttings transport velocity.
• Works for vertical, deviated, and horizontal wells using the Preston Moore Correlation.
• Future updates will factor in ROP, porosity, and other parameters.

Pre-Recorded Well Data Page

• Automatically imports drill string & casing scheme from Well Configuration.
• Displays all essential well data at a glance.

Kill SheetsVertical Kill Sheet

• Designed for vertical well control, as taught in well control schools.
• Enter kick data & shut-in pressures—program generates a kill sheet with step-down charts & graphs.
• Print and bring to the rig floor (for guidance only!).

Horizontal Kill Sheet

• Designed for horizontal well control (not typically covered in-depth in well control schools).
• Uses survey data from Active Survey Listing.
• Enter kick data, shut-in pressures, and kill mud weight—program generates a kill sheet.
• Print and bring to the rig floor (for guidance only!).

Horizontal Well Control Simulator

• Simulates circulating out a gas influx using Driller’s Method.
• Works for vertical, deviated, and horizontal wells.
• Based on constant bottom-hole pressure, with user-defined temperature profile.
• Real-time calculations & plots for:
  • Influx position, height, and volume
  • Pit gain
  • Choke panel readings (DPP & CP)
  • Casing shoe pressure & fracture pressure
• Print graphs & kill sheets for rig floor guidance (not a substitute for official well control procedures!)

Kick Tolerance (New in Version 14.2)

• Calculates kick tolerance (in barrels) based on assumed kick intensity (ppg).
• Uses current well configuration & LOT/FIT data.

Brine Calculations & Salt Tables

• Calculate the exact amount of NaCl, CaCl₂, or KCl needed to mix a brine of specific weight.
• Determine how to mix different brine densities to achieve a target weight.

Detailed Annuli Data

This pop-up window shows various calculated data for each separate annulus section, for the given well Configuration:

• Fluid velocity (ft/min)
• Flow regime (Laminar/Turbulent)
• Pressure loss (psi)
• Length (ft)
• Capacity (bbl/ft)
• Slip velocity (for vertical holes)
• Cuttings transport ratio & velocity (for vertical holes)

User-Defined Plots

• Pump Pressure vs. Bit Depth (up to 5 curves for YP/PV)
• Hookload vs. Bit Depth
• ECD vs. Bit Depth
• Hole Fill vs. Bit Depth (when tripping out)

Liner Cementation (under Construction)

This program has many more features and continues to evolve. Check the Screenshots Page for more details.
