3. Copy Curve
It is advisable to copy the curve data instead of digitizing the second curve when the curves are running close to each other and curve nature is same. E.g. AT curves
a. Select a curve by clicking on it.
b. Click on ‘Copy Curve’ icon.
c. A transparency is shown on top of the curve
d. To Copy entire curve
i. Click on the top transparency.
ii. User is prompted to pick a point where the copied curve will be placed.
iii. It will enable ‘Copy To:’ box. This should be a dropdown box with curves from same segment and track (except the source curve name).
iv. Select the curve from the dropdown list and press Enter
v. If the destination curve has not been digitized, all segments from source curve are copied to destination curve (including off-scales).
vi. If the destination curve already has some digitizing data this message is shown ” Data already exists in this range. Do you want to overwrite?" with Yes No option.
vii. If Yes is selected source curve is copied as destination curve at the point picked by the user.
viii. If No is selected no action takes place.
e. To copy a part of Curve.
i. Mark part of source Curve which you want to copy, by picking two points on the source curve
ii. User is prompted to pick a point where the part of copied curve will be placed.
iii. It will enable ‘Copy To:’ box. This should be a dropdown box with curves from same segment and track (except the source curve name).
iv. Select the curve from the dropdown list and press Enter
v. If the destination curve has some digitizing data between the two depths marked on source data this message is shown ” Data already exists in this range. Do you want to overwrite?" with Yes No option.
vi. If Yes is selected the part of source curve marked is copied as destination curve at the point picked by the user.
vii. If No is selected no action takes place.
f. Use Ctrl-Z or click on ‘Undo’ icon to undo the above steps
4. Shift Curve
a. Select a Curve by clicking on it.
b. Click on ‘Shift Curve’ icon.
c. It shows a transparency at the top of the curve, on which a point was clicked, to identify the beginning of curve data.
d. If the entire curve is to be shifted:
i. Click anywhere within the transparency
ii. Drag the point to the new location, ghost curve will appear while dragging.
iii. Leave the cursor at desired position.
iv. All the curve segments will be shifted to new position.
e. If the portion of the curve is to be shifted:
i. Pick two points on the curve segment to select the portion of the curve you want to shift
ii. Click on the curve between the two picked points and drag the curve, ghost curve will appear while dragging.
iii. Leave the cursor at desired position.
iv. All the curve segments will be shifted to new position, between the two points.
f. Use Ctrl-Z or click on ‘Undo’ icon to undo the above steps.
5. Convert and Import
a. Click on ‘Convert and Import’ icon.
b. It will open a pop for making selection for ‘Convert and Import’.
c. Select the Conversion from the following available options:
a. Conductivity from Resistivity
b. Resistivity from Conductivity
c. Density from Porosity
d. Porosity from Density
e. Non Amplified from Amplified
d. Select the source curve (from where data is to be converted) from the dropdown list.
e. Check the box for ‘Dummy Curve’ if required.
Note: Dummy curve data will also be saved in log-curve file. Also, even though dummy curves are not reflected in prep data, user will be able to identify these curves in ticker when a dummy curve is clicked however NO EDITING is allowed on Dummy Curves. There can only be shifted or removed.
f. Select the destination curve (in which data is to be imported) from the dropdown list.
g. If conversion type is ‘density from’ porosity or vice versa:
a. Select Fluid Density
b. Select Matrix Value.
Note: Matrix value can be different at different depths. Initially complete depth (from top to bottom) of the curve will be displayed in a row. If the user changes the end depth (at which the matrix value is changing), one more row will be created from that depth to bottom depth. User can keep adding any no. of rows till it reached the bottom depth of the curve
h. Following validations are applied on selection:
a. Source and Destination Curves should have only Linear Grid Type.
b. Destination Curve shouldn’t be same as Source Curve
c. If the destination curve already has some digitizing data, it will give the message ‘Destination Curve already digitized. Can’t import the curve’.
i. Click on ‘Convert & Import’ button to import the data in destination curve.
j. Use Ctrl-Z or click on ‘Undo’ icon to undo the above steps.
6. Change Off-scales Tags
a. Select a Curve by clicking on it.
b. Click on ‘Change Off-scale Tags’ icon.
c. It will give 2 options: ○ Selected ○ All. (default is ‘selected’).
d. Select the required option.
e. It will show all predefined off-scale tags for the selected curve (except the tag which needs to be changed) in a dropdown list.
f. Select the destination off-scale tag from dropdown list.
g. Depending on the option chosen (all curve segments or selected curve segment), it will change the tag value either for all the curve segments or for the selected curve segments which are having the same off-scale tag value of selected curve segment. User can change multiple curve segments by pressing ‘Y’ to change or ‘N’ to move to next curve segment of same off-scale tag.
h. Right mouse click will exit from this mode.
i. Use Ctrl-Z to undo the above steps.
7. Create ’Ghost’ curve segment
a. This operation is allowed only on ‘Off-scale’ curve.
b. Click on a curve segment.
c. Click on ‘Create Ghost curve segment’ icon
d. User has an option to move:
a. Selected curve segment
b. All curve segments of the same off-scale tag as that of selected curve segment within any 2 depths.
i. Move individually (each can be moved by a different displacement
ii. Move together (all the curve segments will be moved by same displacement)
c. After the shifting is complete, it will create a ‘ghost’ curve segment in the main curve (from which off-scale curve was created).
d. Note:
i. No editing operation will be allowed on ‘Ghost Curve Segment’.
ii. While using ‘remove’ curve option on off-scale curves, it gives options to user to either delete only the ‘Ghost’ curve or both.
