Appwellco – Your Digital Driller’s Assistant for Safe Well Kill Operations
Appwellco is an essential mobile app designed specifically for drilling supervisors, driller assistants, and rig crews who need fast, reliable, and step-by-step guidance during well control events.
When an unexpected kick or influx occurs, every second counts. This app puts proven well-kill procedures directly in the hands of the operator on the rig floor — no more searching through binders or waiting for the company man to calculate volumes and pressures.

Key Features in This Release
Rapid Well Kill Guidance (Driller’s Method & Wait-and-Weight Method)
Simply input current well data (mud weight, slow circulating rate pressure, kick size, pit gain, casing pressure, drill pipe pressure, etc.), and the app instantly calculates and displays the complete kill sheet with clear, numbered steps.
Real-time Kill Sheet Generation
All critical values are computed automatically:
• Initial Circulating Pressure (ICP)
• Final Circulating Pressure (FCP)
• Kill mud weight
• Stroke counts for each section
• Pump output tables
Print Kill Sheet Directly from the Rig Floor
Connect via Wi-Fi or Bluetooth to any nearby printer and print the complete kill sheet in seconds — perfect for handing to the driller or posting at the choke console.
