EASYDRILL is a
user friendly, fully menu driven
calculator program specifically designed for use by directional drillers.
All of the repetitive tasks, including plotting, projections and
anticollision calculations are easily performed with a few keystrokes. In
addition, a unique
routine allows projections to the
bit, as well as calculation of the required slide course length needed to
obtain the desired inclination and azimuth changes.
EASYDRILL is a survey based planning program. After a survey is calculated, it becomes the tie-on from which a large variety of project ahead options can be accessed. The DD can then decide whether to attempt to get back on the original plan line or create a brand new plan from the current well coordinates.
EASYDRILL was written by a directional driller with over 25 years of field experience.

EASYDRILL will provide you with the certainty and confidence of knowing, at all times, where your well is with respect to the target or plan, what is the best trajectory to follow, and finally, how to achieve this with the tools at your disposal. With all these resources, plus your experience and intuition, you will be able to drill better wells, easier, faster and more accurately.

Following is a listing of the available project ahead/planning modes. The Tie-On can be the last survey, any survey within the survey file or the bottom of the previous projection/plan.

The following screens illustrate some of the powerful calculations that can be performed with EASYDRILL
|The program is fully menu driven. By pressing function keys F1 to F6 you can access all the program functions. In addition, a screen with a short description of each function key is displayed along with the menu keys. Even the on/off function can be performed from the program, when the calculator wakes up, it does so, automatically, at the Survey menu. Data is normally entered through single value or multiple value input forms as the ones on the left. Full editing of the survey files is possible and twenty (HP48) average length well files can be stored at one time. A compression (Zip) routine is provided.|
||The current survey is, by default, the tie-on for all projections. A temporary projections file is automatically set up upon creation of the first projection segment. Thereafter projections can be cascaded at will. You can access the plotting routine at any point. You may also save the temporary projections file into a permanent file and designate it as a plan.|
|The plotting routine is a travelling cylinder along the plan's path. The displayed inclination and azimuth are the values necessary to parallel the plan. Alternately the inclination and azimuth towards the closest point can be displayed as well as whether the object well is approaching or receding.|
||Projections can be made to any of an unlimited number of targets. The target can be shifted along and/or across the vertical section plane azimuth and/or up or down.|
||The Slide Projection routine uses the entered slide intervals and the last two surveys to calculate the sliding DLS. Optionally the program can also take into account the natural building (or dropping) tendency of the BHA. Detailed guidelines on how to estimate these values are found in the manual. Once they are estimated, the program uses these parameters plus the survey to bit distance to obtain a value for the inclination and azimuth at the bit. This projection is automatically stored in the temporary projections file. All the other resources of the program can then be used to calculate the desired inclination and azimuth at the next kelly down depth. Returning to the slide projection routine, the [NEXT] function may be accessed to calculate the needed slide course length that will produce the desired results. This "Next kelly down" projection can, in turn, be compared to the plan or you may access any of the other projection options of the program.|
The program is available in versions either for the HP50g, HP49G+ or HP49G calculators. The program must be loaded into the calculator's non-volatile FLASH ROM. This can easily be done by the user with a PC and a link cable. Furthermore the program is also available in a pre-loaded SD flash memory card that can be inserted in the card slot of the HP49g+/HP50g. NOTE: The SD card is only a venue from which it is easier to load the program into the calculator, once loaded the card is no longer needed to run the program and can be put away or used to load the program into another calculator.
Note: There have been some problems reported with the connectivity software that comes with the CD included with the HP50g. Please write to me and I will email you a version that works.
The program will not function until registration. To register simply send the developer the INTERNAL serial number of your calculator and you will promptly receive a registration code. You may download a fully functional HP49G emulator that will allow you to tryEASYDRILL on your PC. Try before you buy!!
