Drill plan data points can be edited, inserted, deleted, or imported into the drill plan table.
A drill plan point can be edited in the Edit Drill Plan Data dialog box by right-clicking on the drill plan point
and selecting Edit or by double-clicking on the drill plan point in the list or on the chart. See the
Inputting
and Editing Drill Data
section for more information on importing, inserting, and editing drill plan points.
Confidence Points
The confidence points table displays a list of all the points physically measured during the bore and input
into the steering tool file by the computer operator. Confidence points are used to override the calculated
drill path and to force the graphed data to pass through the measured point. The use of confidence points
requires topography and a drill path for reference. The columns in the table include:
Conf.Pt.
– Number of the confidence point as it appears left to right on the profile and plan view
charts.
Dist.
– Distance from where the tool enters the ground (Rod 0) to the specified confidence point.
Units are those displayed in the job information field for depth.
Depth
– Vertical distance from the terrain surface to the specified measured confidence point.
Units are those displayed in the job information field for depth.
Course R/L
– Distance right, R, or left, L, from the reference heading line to the specified
measured confidence point on the plan view chart. Units are those displayed in the job informa-
tion field for depth.
Confidence points can be edited, inserted, deleted, or imported into the confidence points table.
A confidence point can be edited in the Steering Confidence Point dialog box by right-clicking on the
confidence point in the table and selecting Edit or by double-clicking on the confidence point in the table
or on the chart. See the
Inputting and Editing Drill Data
section for more information on importing,
inserting, and editing confidence points.
Chart Area
The profile and plan view charts give a graphical representation of the information contained in the data
tables and can be annotated to provide additional details about the job. The common features of the two
charts are discussed below. See the help topics in the LWD software for more information.
Graphed Points
– Data points, drill plan points, terrain (topology) points, and confidence points
that have been logged or imported and have not been hidden or deleted display in the chart area.
Axes
– The X and Y axes of each graph are labeled for the type of data contained in the chart.
The X-axis of each chart shows the horizontal distance from the drill. The Y-axis of each chart
differs, as discussed below.
Cursor Coordinates
– When the cursor is placed anywhere in the chart area, the value of the
coordinates at that position display. If the cursor is placed on a data point, all values recorded at
that data point will display.
Zoom
– To zoom into an area of the chart, hold down the control button on your computer then
click and hold (control-click) on your mouse while you drag the pointer through the area you wish
to explode. Release the mouse button once the area is selected. To return the chart to its normal
scaling, control-click anywhere in the chart area.
