Course 3: Using Basic Well Editor Tools Can open multiple files and sort by different parameters Change applying a constant value to replace Select curve> Identify start and end points Manually draw in a curve; linearly interpolated Multiply log values over a specified interval by a value Replacing values with the average 1 st click and hold Drag over values Release to mark first point Mark end of this int and successive ints by 1 st click and hold Drag over values Release to mark first point Mark end of this int and successive ints by a horizontral green line Insert a constant value Multicurve then insert from the edit menu Specify a starting point This will shift the curve down Have user specified value, interpolate or null Remove log data from a specified interval Shift start depth Edit > Multicurve > ShiftData is either shifted up or replaced with nulls. Shift down (+) up (-) Shift start depth by specified amount Stretch and Squeeze Smooth curve (3 filter types and filter length changes) Edit formation tops Click and refresh to display new top picks Edit > formation tops Click in KB cell then click the top location from one of your logs. Edit > Curve Header, Define Curve and Create Lithology Strip Change curve label to SONIC WET Curve mnemonic by default As a footnote: when generating AVO synthetics, the foregoing comes in handy. Edit > Curve Header Select PR Edit Label/Type Define curve category as Poisson Ratio OK When first reformatted Curve params read Define curves dialog are based on options sleeted in the well editor preferences dialog Edit > Curve Header Select SFL > Define curves Select SFL > in userdefined list Change curve label to Spherically Focused Resistivity > Append Append adds the label to the user defined curves list OK to exit > close edit curve header panel Getting Started on AVO Synthetics ZE/ZEcrewes.html Poisson ratio =0.33/0.33 AVO.xls Poisson ratio =0.33/0.19 Redefine curve mnemonic> add spherically focused resistivity to the user defined curves list Create lithology Strip View > Track paramters Select all 4 tracks Apply Select all 4 tracks (click and Shft Click Change track width and Gap width Edit > Lithology Track Change curve label and click in the area between tracks to insert your lithology curve > Insert here Click on the Course Lith track and click on the top to auto fill the start depth. Do the same for the base (end depth). Use scroll bar to select patterns and apply to fill lith track with color. The proceed as before clicking in the start and end depths and lithology patterns File > Save as > Log M Well Well ID has been changed to reflect display content. Generic curve fills only need to be defined once and are defined in all wells displayed in cross section Zoom all to fit curves to window View > select curves Note more than one curve per track OK to display Edit > Curve Fills Well Specific Well Editor > Open well > Select well > OK Zoom all > View > Select Curves From select curves to display dialog Edit > Curve Fills Specify fill parameters and relationships as shown below> OK File > Save as Composite curves (single well) Edit > Composite curves Select source well > Select Source Curves> gamma ray > OK Destination curve Select Source curves Then click start depth for Destination depth What it seems to do is to duplicate a portion of a log as shown below. Or to replace a portion of the log beginning at 3570 with the log response between 3025 and 3175 Multiple well composites > take deeper part of one well and tack onto another well. Open > Select two wells Edit > Select Formation tops > Plot All > Refresh to add > OK to exit Activate one well Select formation tops from Edit menu > Plot None then Plot All > Refresh > OK Edit Composite Curve (the edited well is the destination well) Select the well on the left as the source well Select Start depth in the destination depth box by clicking on the destination well to show where you want replacement to begin That will transfer the Start-End interval from the source well to the destination well beginning at 5217 feet > File > Save As > LogM> OK Change name > OK > your new label should appear in the title bar of the destination well. Create synthetic traces for a well Select and remove Click between logs to define display location. Zoom in > Edit > Curve > Draw Select Curve and track opens > Select Sonic > OK Edit Curve > Draw > Edit other curves > Save Phase and Frequency Open well > Synthetic > Create Synthetic > Wavelet > Add Phase and Frequency panels & add wavelet each time. Click area to place Save as > logM > OK Exploded Synthetics > Block logs Open a well View > Select curves > Clear All and rearrange Then save as giving it another name indicating it will be a blocked log file format Zoom over both wells to get View Vertical Scale, Ctrl C, Cancel > open other well copy and OK to apply change Activate second log display and click View > Align wells > select Formation top radio button and select a formation. The logs should be aligned Edit > Curve > Block> Select sonic curve > OK Change start and end depths for blocking Close and then block the density log Close > Synthetics > Exploded Synthetics > Save as logM file modify name to exploded synthetic Deviated well synthetic display You can import a deviation survey then Synthetics > Synthetic > OK Create synthetics dialog; use Sonic and Density for RC > choose/design your wavelet > click display area to insert View > Deviated Dispay Clear > select track placement Export synthetics to sgy
