OpenWorks Software Data Management Introduction

4 Sending Data Between Applications 5000.8.1.0

Sending Data Between Applications

One of the main features of most of the utilities and applications of theOpenWorks software is data communication between themselves. In

this context, you might find references in the manual that you can senddata with the Pointing Dispatcher service.

A window that is ready to accept data has a green border indicating thatit is in the listening mode. A window that is not in the listening modehas a red border. You can toggle between the red and green border byclicking it. When you send data with the Pointing Dispatcher service,it is accepted by any application that is in the listening mode.

Some utilities of the OpenWorks software have a Send menu as part ofthe utility. If they do, select Send All or Send Selected from the Send

menu to send data with the Pointing Dispatcher service. Otherwise,place the cursor over the data to be sent, and press Shift-Button 2.

For more information on sending data with the Pointing Dispatcherservice, refer to the Online Help.

Checkshot Data Manager OpenWorks Software Data Management

5000.8.1.0 Overview 5

Checkshot Data Manager

Overview

The data model of the OpenWorks software stores checkshot surveysin the time-depth curve and vector tables (time_depth_curve andtime_depth_vec).

The Checkshot Data Manager is a quality control utility that allows youto:

View time-depth tables graphically

Edit or delete time-depth pairs

Merge two time-depth tables

Generate time-depth tables

Delete time-depth tables

The Checkshot Data Manager writes data to the time-depth curve andvector tables. Corresponding to the time-depth table in the CheckshotData Manager, the OpenWorks software allows you to load time/depthpairs that use different reference elevations for the depth of the tool(Depth Datum) and the energy source for the time measurement(Survey Datum). The difference in elevation between the KellyBushing and sea level may be significant.The ability to specify dualdepth and time datums allows the OpenWorks software to correct forany significant elevation difference as values are loaded. The SurveyDatum is used for the datum of the created time/depth table and theDepth Datum is not stored. All depth values are adjusted to referencethe Survey Datum.

10 Displaying Checkshot Surveys 5000.8.1.0

Displaying Checkshot Surveys

Checkshot surveys are displayed as time-depth curves. Each square inthe curve represents a data point. If a well has multiple checkshot

surveys, you can display several or all of them simultaneously. Theactive (selected) survey is displayed in black.

You can vary the display by changing the time units (s/ms) and timemode (one-way, two-way). These changes are discussed on page 24.

Selecting Checkshot Surveys

To select and display checkshot surveys:

1. Select a well list from the Well Listspanel.

All the wells in that particular list are displayed in the Well Namespanel. An asterisk (*) before a well name indicates that the wellhas a time-depth table.

2. Select a well from the WellNamespanel.

All the time-depth tables available for that well are listed in the TDTable panel. An asterisk (*) before a table name indicates that it isa checkshot survey.

3. Select a time-depth table.

The time-depth curve is drawn in the display area. Each square onthe curve represents a time-depth pair.

4. Select additional time-depth tables for this well, if desired

Each time-depth curve is drawn in a different color.

Making a Survey ActiveClick on the time-depth curve you want to make active.

The curve displays in black, and the data point closest to where youclicked displays in yellow. The name of the corresponding time-depthtable is posted at the top of the window. The active curve is nowavailable for editing.

Selecting wells with the Pointing Dispatcher service

You can also send a well selection from another application to the Checkshot DataManager via the Pointing Dispatcher service. For example, you might want to

send a well list or a few individual wells from the Well List Manager. These new

wells are simply added to the current list of well names in the Checkshot Data

Manager.

Conversely, you can send a single well from the Checkshot Data Manager to

another application by clicking on it in the Well Names panel with

+Button 2.

12 Displaying Checkshot Surveys 5000.8.1.0

Bringing Surveys to the Front

When a curve is active, it is brought to the front. That is, it is drawn ontop of all the other curves so you can see it clearly and work with it.

To view a curve that is obscured by an active curve:

1. Select Edit > SendTable to Back from the menubar, or pressButton 3for the popup menu and select Send Table to Back.

The active curve is drawn first and the other curves are drawn ontop of it. You can now see the desired curve better.

2. To return the active curve to the forefront, select Bring Table to

5000.8.1.0 Merging Time-Depth Tables 17

Merging Time-Depth Tables

You can merge two time-depth curves to produce a new time-depthtable.

If the two curves have:

distinct depth ranges (no overlap), the last point on the upper curveis simply connected to the first point on the lower curve. All thetime-depth pairs from both curves are retained in the new, mergedtable.

overlapping depth ranges, you must specify a merge point on theupper curve. The curves are spliced by joining the merge point onthe upper curve to the next deeper point on the lower curve. Thedata points above the merge point are taken from the active survey(upper survey) and the data points below the merge point are taken

from the second survey.

An example of merging two overlapping time-depth curves follows.

Always make the shallower curve active.

The merge operation proceeds from the active curve downward. Therefore, ensure

that you make the shallower of the two curves active before selecting Merge

Tables.

40 Merging Deviation Surveys 5000.8.1.0

Merging Deviation Surveys

You can merge two deviation (or directional) surveys, splicing them toproduce a new survey.

If the two surveys have distinct depth ranges (no overlap), the lastpoint on the upper survey is simply connected to the first point onthe lower survey. All the data points from both surveys are retainedin the new, merged survey.

If the two surveys have overlapping depth ranges, you mustspecify a kick-off, or merge point, on the upper survey. Thesurveys are spliced by joining the merge point on the upper surveyto the next deeper point on the lower survey. The data points abovethe merge point are taken from the active survey (upper survey)

and the data points below the merge point are taken from thesecond survey.

An example of merging two overlapping surveys follows:

5000.8.1.0 Generating a Position Log 47

Generating a Position Log

Landmark applications such as the SeisWorks software, requireposition logs to display deviated wells properly.

You can easily generate a position log from a directional survey. Thedeviation data (inclination and azimuth at specified depths) is used tocalculatex,yvalues (absolute coordinates and offsets from the surfaceposition of the well).

Five methods of computation are available. These methods werediscussed in detail by Craig and Randall1and are summarized below:

Radius of Curvature: based on sets of angles measured at the topand bottom of the course length. These measurements are used togenerate a curve that represents the wellbore path. Craig and

Randall consider the radius of curvature method to be one of themore accurate.

Minimum Curvature: based on sets of angles measured at the topand bottom of the course length, smoothed onto the wellbore curveby a ratio factor defined by the curvature of the wellbore. Thismethod, like the radius of curvature method, is recommended byCraig and Randall.

Balanced Tangential: based on inclination and direction angles atthe top and bottom of the course length. This method yields asmoother curve than the tangential method (see below).

Angle Averaging: based on the angles measured at the top andbottom of the course length, with the simple average of the two.

Tangential Method: based on the inclination and direction anglesat the lower end of the course length. According to Craig andRandall, this is the least accurate method and its only advantage isthat the calculations can be done readily by hand.

If a position log already exists for the well, a confirmation boxdisplays, asking if you want to overwrite it.

4. Select the checkbox if the Directional Survey is referenced to trueNorth.

The OpenWorks software corrects for grid convergence andscale factor. If you do not select this checkbox, The OpenWorkssoftware assumes that the Directional Survey is referenced to gridNorth.

5. Click Yesin the confirmation box.

The new position log is generated.

To check the position log, use the Well Data Manager.

Generating a new position log overwrites the existing one

Only one position log is allowed per well. When you generate a new position log

from a deviation survey in the Deviation Data Manager, the application will warn

you if a position log already exists for the well and asks you if you want to

overwrite it. If you choose yes, the wells current position log is immediately

eliminated and replaced by the new log.

Field List Manager

Overview

The Field List Manager allows you to create lists, or subsets, of thefields in an OpenWorks project. Field lists are particularly useful forlarge projects because they allow you to focus quickly on the fields ofinterest, thus reducing data retrieval and display time.

With the Field List Manager, you can:

use filters to selectively retrieve fields from the database.

use filters to choose among the fields you have retrieved.

send fields to or from other applications via the PointingDispatcher service.

edit existing field lists.

view basic information on the wells, financial interests, andboundaries of a given field.
