See the build rate, dog leg and tool face needed for the planned TVD, inclination and vertical section. Project to the bit and see whether landing VS is short or long.
DIRECTIONAL DRILLING SOFTWARE
Land the curve
from your pocket.
Your well plan. Your surveys. The tool face, slide and build rate it takes to land on target—all on your phone.

01 / THE NEXT STAND
Know what it
takes to land.
CurveDrill brings your plan, surveys, slide history and landing target together. At every survey, see what the next stand needs to get you there.
Choose your way back.
Compare two tool face options side by side: one aimed at the plan line and landing point, and one for angle and direction only.
Let the slide log do the math.
Enter each slide once. CurveDrill calculates slide seen, slide ahead and motor yield from your slide footage.
Keep the rig-floor entry simple.
Type the bit depth and survey. Your sensor offset handles survey depth, while the app works out depths and calculations.
Start with your Excel plan.
Import the plan you already have. Keep several wells and switch between them, with no project database to build or laptop software to install.
Carry it into the field.
Install from your browser on iPhone or Android. Work without signal once installed, with wells and surveys stored on your device.
02 / WHAT’S IN THE APP
From the first import
to the last curve survey.
The tools for the whole curve job, in a format made for the phone you carry.
01Plan & setupBring the well plan you already use.
- Import Excel plans with MD, inclination and azimuth, plus TVD, N/S and E/W when available.
- Read the plan’s vertical section azimuth and check your VS direction against it.
- Keep multiple wells and switch between them.
- Set sensor offset and stand length once.
02Surveys & slide logEnter once. Keep the calculations connected.
- Calculate minimum curvature surveys from a tie-in that includes VS.
- Enter bit depth throughout the app. Sensor offset converts it to survey depth.
- See VS, dog leg, build rate and motor yield at every survey station.
- Log manual From and To slide depths. Slide seen and slide ahead are calculated automatically.
03Live curve guidanceKeep your bit, plan and landing in view.
- Running inclination (RINC) between surveys, with running motor yield.
- Projected inclination and azimuth at the bit.
- Two tool face options: back to the plan line and landing point, or angle and direction only.
- Build rate, dog leg and slide versus rotate needed to land, recalculated at each survey.
- Landing VS short or long of the plan.
- Left/right and above/below the plan, measured by closest approach perpendicular to the plan.
- Next survey point with bit depth and survey depth for the next stand. Enter inclination and azimuth straight into the survey list.
04Plot & phone experienceSee the well. Take it with you.
- Side, top and 3D views of the plan, surveys, projection to the bit and path to landing.
- Rotate the 3D view with one finger and pinch to zoom.
- Install from the browser on Android or iPhone. Works offline once installed.
- Large, high-contrast numbers, with light and dark modes.
- Well plans and surveys stay on your device. The app checks your license when online; an online re-check is required every 30 days.
03 / CURVEDRILL & THE OUIJA BOARD
Keep the whole
curve in view.
A basic paper or spreadsheet Ouija Board answers one geometry question at a time. CurveDrill connects that next decision to your plan, surveys, slide history and landing target.
Swipe the table to compare both columns →
| On the job | Basic Ouija BoardPaper or standalone spreadsheet | CurveDrillOn your phone |
|---|---|---|
| The next stand | One geometry answer per setup: a tool face or a change in inclination and azimuth. | Tool face, build rate, dog leg and slide needed to land. |
| Your well plan | Compare the result with your plan separately. | Import Excel plans. See left/right, above/below and landing VS short or long. |
| Projection to the bit | Work it out separately. | Built in from the last survey, slide log and running inclination. |
| Motor yield & slides | Calculate yield and keep the slide record separately. | Per-survey and running motor yield. The slide log feeds slide seen and slide ahead. |
| Tool face options | Set and read for the individual geometry question. | Two options on screen: back to the plan line, or angle and direction only. |
| Calculation method | Dog leg geometry for one step at a time. | Minimum curvature across the well, recalculated at each survey. |
| Where you use it | Paper, a spreadsheet or a laptop. | On your phone, installed like an app. Works offline once installed. |
Desktop Ouija modules within rig-site planning software can connect to a plan and slide sheet. This comparison describes a basic standalone workflow. CurveDrill brings the rig-floor part of that job to your phone.
