The rig's calculations, in one place you can trust
Type your well once and DrillPro works out the rest: volumes, strokes, pressures, fills and the schedule, drawn and checked on screen, ready to print or send.
Kill sheets that keep up with the well
Enter shut-in pressures, pit gain and your slow circulating rates, and the whole kill sheet is ready: kill mud weight, ICP and FCP, MAASP, strokes and minutes for every part of the well, and the pressure step-down schedule with its graph.
- Lite and advanced surface kill sheets
- Step-down tables per 100 strokes and per tenth
- Every mud pump and SCR reading on the same sheet
- A detailed breakdown of every capacity, length and weight
- Kill mud
- 11.8 ppg
- ICP
- 940 psi
- FCP
- 548 psi
- String volume
- 208.4 bbl


Five ways to look at the same well
Every casing, liner, open hole section and string component is drawn and labelled with its depth and ID the moment you type it. Switch between engineering, stepped, simplified, geological and plot views, true scale or exaggerated.
- Liner tops, shoes, bit and BHA marked on the depth track
- Light and dark themes, full screen on any device
- The same drawing goes into your reports

Catch a gain on the stand it happens
The live trip sheet compares the calculated fill with your trip tank readings stand by stand. Interval and cumulative differences are worked out as you go, and a stand that takes too little or too much is flagged in red at once.
- Pulling out or running in, wet or dry
- Trip tank limits, warnings and re-zero
- Stands and single joints from your string

Volumes, strokes and times without the spreadsheet
String, annulus, bit to shoe, bottoms up and the whole system, in barrels, strokes and minutes for the pump you choose, for any mix of casing, liner, open hole and tapered string.
- Tapered strings, liners and extra surface volumes
- Capacities from the data sheets or your own IDs
- A schematic of the well under the results
- Bottoms up
- 602 bbl
- Strokes
- 5,042
- Time
- 85 min
- Whole system
- 823 bbl


Tallies that add themselves up
Type, paste or photograph your lengths and the tally fills itself: running totals, stands, total with BHA, air and buoyed weight, capacity and displacement, with a check that flags a short, long or doubtful joint. Build the BHA from the bit up, then join them into one string.
- BHA, drill pipe, casing and combined strings
- Serials, connections, ODs, IDs and fishing necks
- Excel-style editing, formulas and Format mode
- PDF and Excel exports, saved in Flying Brain
- Joints
- 60 · 20 stds
- Length
- 1,856.65 ft
- Air weight
- 28,778 lb
- Checks
- No problems


Your mud tanks and pumps at a glance
A live board of every tank: level, volume, empty space and dead volume, active and reserve, with totals for the whole system. Pump output comes from liner, stroke and efficiency.
- A board laid out like your rig: drag and size every tank
- Fill, pump and transfer between tanks, with a log
- Rectangular tanks and vertical or horizontal silos
- Triplex and duplex pumps in bbl and gal per stroke


The drilling data book in your pocket
Tubular and flange data sheets for drill pipe, HWDP, collars and casing, a library of drilling formulas, and an oilfield unit converter with hand tools, all searchable.
- Tubular weights, capacities and displacements
- Formulas with the equation on every card
- Depth, pressure, volume, flow, torque and density units

Smart Me goes where you go: phone, tablet or computer.
Ask in plain words, type numbers or send a photo of a report. Smart Me opens the right calculator, fills it in, and the app shows its own results, so you can check every number. Your files become its memory in Flying Brain.
- Fills kill sheets, trip sheets, volumes and tallies for you
- Reads data sheets, reports and spreadsheets you give it
- Works in your language, Arabic included
- “Give me your SIDPP, SICP and mud weight and I’ll fill the kill sheet”
- “Describe your casing and string, I’ll build the well”
- “Pump output from liner size, stroke and efficiency”
