How to Run R3 on a Mac

Have a Mac and want to evaluate your oil and gas assets with R3? Not a problem!

In order to run Windows on Mac, you need to have a copy of the Windows Installation File (DVD disc or .ISO file) before you can run Windows on a Mac.

There are two ways to run Windows on a Mac,

1.  Install Windows through Boot Camp

Install your separate Windows System on a Mac

Boot Camp allows you to install Windows alongside OS X on your Mac. Only one operating system can be running at a time, so you’ll have to restart your Mac to switch between OS X and Windows.

Here are useful links:


2.  Run Windows through a Virtual Machine

Virtual Machines like Parallels could allow users to execute Windows application within Mac OS

A virtual machine is one of the best ways to run Windows desktop software. They allow you to install Windows and other operating systems in a window on your Mac desktop. Windows will think it’s running on a real computer, but it’s actually running inside a piece of software on your Mac.

Once you have access to Windows on your Mac, you can install OGRE R3 with a few simple clicks. 


Using Multi Sensitivity form and US_Sensitivity model

This article will explain how to use the Multi Sensitivity form. What this form does is allow you to see how changes would affect your well. Changes that will affect the economics of a well include changes to:

  • Production
  • Price
  • Variable Costs
  • Fixed Costs
  • Capital Expenditures

You can evaluate variables in all of these areas, one area, or any combination.


When you click on the Multi Sensitivity form you will see this:


The form is divided into two sections. The top section is where you will enter your inputs. The bottom section is where the results are displayed after you run the appropriate models.

Sensitivity Inputs: These inputs are multipliers. For example: If you want to see what effect a 10% price increase would have on the NPV you would enter 1.1 into one of the sensitivity fields within the Price column. If you want to see the effect of a 10% decrease in price you would enter 0.90. The model will multiply the price you entered in the Price and Prod Tax form by this entry.

You can use as many or as few of these fields for your evaluation.

Results: This portion of the form will only be populated or updated when you run the appropriate models. (More information on that below.)

There are five tabs in this section, Production, Price, Variable Costs, Fixed Costs, and Capital. What is displayed is the result of the Sensitivity evaluation based on the corresponding inputs entered in the top portion of the form. Each tab will display different results based on the inputs corresponding to that tab.

The Process:

  1. The first thing you need to do is make sure that all of your data is entered correctly for Production Forecast, Price, Costs, Ownership, Capital, etc..
  2. On the Multi Sensitivity form you will enter the sensitivity multipliers you want to evaluate.
  3. Click the  Model icon to configure the model run. You must use the Advanced tab to set the Primary Model Override to use the model: US_Sensitivity. 
  4. Click Run. 
  5. To see a report about the NPV you will click the  report icon and select one of the sensitivity reports:


When the model run is complete you will also see the results of the sensitivity calculations in the lower portion of the Multi Sensitivity form. This results section of this form actually shows the most information about how different sensitivity multipliers affect all other factors. For example, you can see that if you have the No Loss feature enabled, a change in price will affect the production because with a lower price, the well becomes uneconomic sooner resulting in less production. Those relationships are seen on this form.

What do we mean by the terms "Digital Stream" and "Analog Stream"?

When reading Knowledge Base articles or talking to support we will sometimes refer to Digital Stream and Analog Stream. This article explains what those are.

Digital Stream

A digital stream is a set of data that has defined increments of time which, depending on the data type used for the stream, can be Daily, Monthly, Quarterly, Semiannually, Yearly, or Undefined. The data in each cell is defined specifically by either manually entering the number, referencing another source either externally or within the software, inheriting the data, or importing the data from an outside source. But the specific number in each cell for each time increment can be changed manually. The digital stream will be some variation of this:



A digital stream can be used for production forecasting, production history, price, cost, and any other stream of data that might change from one month to the next, or one year to the next etc..

Analog Stream

An analog stream does not show date increments, but rather a beginning and ending date. The analog stream is a calculation of production forecasts based on inputs. The data that can be used to calculate the forecast include:

  • Start date
  • End date
  • Initial rate
  • Final rate
  • Curve type
  • Initial decline
  • Ending decline
  • Remaining
  • Prior @ PDS
  • Ultimate

There can be other factors but basically when you provide enough information, the rest is calculated. For example, if you provide a Start Date, Initial Rate, Final Rate, Curve Type and Initial Decline, the software will calculate the End Date, Remaining, Prior @ PSD, and Ultimate. If you were to provide the End Date, but not the Final Rate then that number will be calculated instead. Basically, with enough information provided, it will calculate the other fields. This means that the forecast for any given time increment will be calculated rather then manually entered for each increment. The analog stream will look something like this:

 Again, the analog stream is only used for production forecasts whereas digital streams are used for many different things and types of data.

Using the Well Scheduler

The Well Scheduler allows you to create a number of wells based on a Type Well.


When you create a drilling schedule, the newly created wells will have the same parent asset as the Type Well used. As such to create the well schedule you will find your Type Well in the Study tree and right click on the parent asset and choose Well Schedule:



You will get a dialog box to specify the schedule.


Here is what each of the columns represent:

Template Asset: This is the asset you want to use as your Type Well.

Start Date: This is the date that the drilling will start for this segment of the schedule. By default it will be today's date.

PSD Delay Months: This is the number of months between the completion of the drilling increment and the date used for the Production Start Date (PSD).

Number of Wells: This is the total number of wells that you intend to drill for this segment of your well schedule.

Interval Increment: This is the number of months it takes to drill a well.

Wells Per Increment:  This is the number of wells that will be created in each increment of the well drilling schedule.


Some examples

If you have three drilling rigs that each take two months to complete the drilling of a well and plan to drill 10 wells, you would enter 10 for the Number of Wells, 2 for Interval Increment and 3 for Wells Per Increment. 

Using the scenario above, if two of your rigs can drill a well in two months, but the third rig requires three months to drill a well, then you would need to use one line for the first two rigs and a second line in this well scheduler for the third rig,

If you plan to drill a number of wells, then take a break (perhaps because of weather) and then pick up again and continue the drilling schedule, then you would need to use one line in this well scheduler for the first segment of the drilling schedule, and another line for the next segment, the key thing to pay attention to here is the Start Date. 

If you need to use different wells as your type, you need to use a new line for the new type.

You can list several entries for the schedule using different wells as templates (type) or even the same might see something when you're done that will look like this:


When you complete your schedule configuration, click Create. The wells will then be created and appear as sibling assets to the Type Well:

You can now rename each of the new assets to appropriate names.

Importing IHS Data

Importing IHS data

When you need to import IHS data from a .dp2 file, click File > Transfer (Import/Export). 


Since this is the same option as exporting make sure you specify Transfer In. 

You will need to browse to the .dri file to import.

Click Next chose what data you want to include.

You'll need to choose if you want to Update, Insert, or Reorganize your data. We'll go through each of the options.



You'll need to specify the study that has the data that is being updated, and you'll need to identify the key that you will use to match the IHS data to the right asset in your database. API Code is a popular key because it is always unique. Click Finish for the transfer process to complete.


Specify what data you want to include with the import of the IHS data and click Next. If you want to import all of the IHS data then select that asset in the left hand panel. Note that the IHS Root appears as an asset with children. When the import is complete, IHS Root will appear as an asset in your tree, and in this example it will be a child of the NM asset. Click Finish to complete the process.


The Reorganize option works the same way as the main Reorganize option works which is documented in the article titles How to use the Reorganize feature.
