Appendix F–Slide Sheet Column Options

Start Depth: Start depth of the operation

End Depth: End Depth of the operation

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

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.

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

MY: Motor Yield average used for Bit Projection

MY Avg: Motor Yield Average – Average calculated using the previous 4 motor yields

Rot DLS: Dogleg seen while rotating

Rot TF: Toolface seen while rotating

Proj Inc: Projected Inc at the bit. Projected from the previous survey – data used by Criterion to determine directive

Proj Azi: Projected Azimuth at the bit. Projected from the previous survey – data used by Criterion to determine directive

Proj UD: Projected distance (at the bit) Up / Down from plan – data used by Criterion to determine directive

Proj LR: Projected distance (at the bit) Left / Right of plan – data used by Criterion to determine directive

Proj Delta Inc: Projected difference in inc from plan – data used by Criterion to determine directive

Proj Delta Azi: Projected difference in azi from plan – data used by Criterion to determine directive

DLS to Land: Criterion’s calculated dogleg required to land

Slide Length: Criterion’s recommended Slide Length directive for the next interval

Slide DLS: Dogleg achieved over the slide interval

Convergence: Amount of maximum degrees, whether inclination or azimuth, that Criterion will use to converge back towards the plan

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

WOB: Weight on bit - Manually entered or taken from WITS feed

Flow Rate: Pump flow rate - Manually entered or taken from WITS feed

RPM: Drill string rpm - Manually entered or taken from WITS feed

Tq: Off bottom torque - Manually entered or taken from WITS feed

ROP: ROP for the interval - Manually entered or taken from WITS feed if Rig States are recorded

PU Wt: Pick up weight – Manually entered or taken from WITS feed

Rot Wt: Free Rotating Weight - Manually entered or taken from WITS feed

SO Wt: Slack off weight - Manually entered or taken from WITS feed

Off Btm Press: Off bottom pump pressure - Manually entered or taken from WITS feed

On Btm Press: On bottom pump pressure - Manually entered or taken from WITS feed

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

Comments: Comments relating to the interval

Start Time: Start time

End Time: End time.

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.
