ProMAX Tutorial Faisal

A. ProMAX Introduction Interface ProMAX is using 3 button, left, right and middle one.

Generally, Promax is formed by 3 level structure of workspace; AREA, LINE, FLOW. When the first time user make the project, user has to define that 3 level of workspace. AREA must be defined as the name of survey’s area. The second one is to define the line of the survey’s seismic. Finally FLOW must be defined as step-by-step from seismic processing.

B. ProMAX Workspace 1. Workspace Area Some Command are using in the workspace area are Select, Add, Delete, Rename, Copy, and Permission.

Choose Add Command in the area workspace window to define the new area by clicking the left handed mouse and then type name of the area and then press enter. 2. Workspace Line Having a common with the workspace area, choose the add option and then type name of the line survey’s name.

3. Workspace Flow There are some of the command in workspace flow doesn’t exist in other workspace, such as Dataset and Database. Dataset

: Showing the list of entire dataset that are or have been generated at the existing line.

Database : Allow the user to access all files on the parameters which have been generated at the existing line.

Choose Add command on the flow workspace window and the type name of flow from the processing flow to be done and the press enter. 4. To Make and Execute the Flow By clicking on the name of flow that the user has been made, user will go to the new editing window. Generally that window is made by 3 part ; a. Available Process This part is showing some of the command that available in this section to process seismic data. b. Editable Process This Part is showing all commands that have been chosen by the user which available in available process section. All the commands that have been selected into the editable process is like an algorithm, which means at this section will be run sequentially from up to bottom.

c. Parameter Specification Parameter Specification window is showing all the paramaters that have been selected by user to execute the command. Generally, seismic processing flow can be made and executed with step by step like this below: a. Select the subflow that is required in available process and then put it into editable process. User can search all subflow by typing initial or full name of subflow. b. Click MB2 on one of subflow which have been listed in editing flow section to show the window that contains all the parameters that must be determined by user to execute the flow. c. Some of subflow which contained in editing flow section can be canceled or waived by clicking MB1 in one of the subflow that user wants to cancel. And then followed by clicking MB1 on Delete at top of the editing flow section. d. All of the command that have been listed and had all the parameter set in editing flow section can be run by clicking Execute

1. Input Data At this section, Seismic Raw Data will be read. Pada flow ini dilakukan pembacaan raw data seismik, according to parameter which have been defined by seismic data tape. a. Input raw seismic data in accordance with the format of data storage media (tape) that has been determined. Suppose the raw data is stored in SEG-Y format, then commands used are SEG-Y Input. b. Give the name on the output dataset raw data as RAW DATA using Disc Data Output.
