Appendix F - Slide Sheet Column Options

Date: Date of operation

Start Time: Start time of the operation

End Time: End time of the operation

Hrs: Number of hours of the operation

Start Depth: Start depth of the operation

End Depth: End Depth of the operation

CL: Course Length – The course Length between the Start and End depths displayed in the slide sheet.

State: Choose Slide or Rotate from the drop-down menu

TF Type: Magnetic (MAG) or Gravity (GRAV) Toolface

TTF: The Target Toolface the directional driller is aiming to slide on.

ETF: Effective Toolface calculated over a slide interval. This will be populated automatically under the following conditions:

• WITS data is being received and the WITS data reader is on.

• Auto populate slide sheet is selected.

• Rig States parameters for a slide are being fulfilled

Well Seeker calculates the ETF by taking each recorded toolface and calculating the distance drilled on this toolface. If survey and toolface data is being saved (option via the WITS Reader), then this data will be available to view by double left clicking on the line in the slide sheet which will open the Slide Analysis dialog.

MY: Motor Yield average used for Bit Projection

Steer Force: The steer force used by the RSS over the interval

Slide Grade: Displays the grade of the slide. This is related to the ETF and will populate automatically after a slide if survey and toolface data is being saved (option via the WITS Reader). If the slide is perfectly on one tool face for the entire slide this would give an output of 100 as the slide went in exactly the same direction the whole time. If the slide was not consistently on a steady tool face, then this value will be less than 100. The lower the value, the worse the slide.
