How do I match a PVT model to laboratory data?
In the laboratory-data matching workspace, click Add and enter the test date, temperature and measured property series. Select the properties to match and click Match. Oil matching supports bubble point pressure, solution gas-oil ratio, formation volume factor and viscosity; gas matching supports viscosity and Z-factor.

How do I create a material balance model in MBAL?
In the Navigator, create a material balance reservoir model, load it and unlock it for editing. Click Add to create a tank, enter its name and type, then configure General data, including initial pressure, porosity and a previously created or imported PVT region.
Read more:
Where do I enter production and injection history?
Use the Operation history tab to enter tank pressure, oil, water and gas production, gas and water injection, and matching weights for each history interval. Values can be entered manually or pasted from a prepared table. Link a well to its tank before entering well-level history.

How do I match an MBAL model to actual data?
Use the model-matching topics to select the appropriate matching task and review its procedure. The historical-calculation instructions describe how to run the model against historical data.

How do I run a forecast in MBAL?
Add forecast steps through Calculation steps, specify the step length and number of steps, and set the first forecast step. Save and confirm the steps, then click Calculate model. Forecast values appear in the Indicators table; Plots and Energy contribution provide additional results.

How do I create a well model and enter its input data?
Create a model on the Well Model tab, load it and unlock it for editing. In General information, select the PVT model, well purpose, lift method and flow correlations. In Well construction, enter deviation survey, downhole equipment, heat transfer and gauge data.

How do I calculate the pressure gradient in a well?
On Pressure gradient, choose tubing head pressure or bottomhole pressure as the calculated variable, then enter the other pressure, water cut, gas-oil ratio and flow rate. You can use Fill from test to load a measurement. Click Calculate pressure gradient and review the table and plots on Calculation results.

How do I include methanol injection in a WELL calculation?
For a naturally flowing well, use the Methanol injection tab. Enter the methanol solution injection rate, temperature, fraction, water density, casing head pressure, and injection depth for the pressure gradient calculation.
Read more:
Where can I configure well-model matching?
Enter measurements on Well model matching, select a measurement and open Correlation comparison. Click Load test data, select multiphase flow correlations and click Calculate to compare them with the measurement. The Matching tab provides automatic matching.

How do I create an integrated model in PIPE?
On Integrated Model in the navigator, create and name a model, load it, then load the required network. Unlock the model for editing. Use the Object navigator to select and configure objects in the network.
Read more:
Where do I enter input data for PIPE objects?
Select an object in the Object navigator to edit its parameters. The form changes with the object type, such as a well, joint or pipeline. Use Add and Delete to manage input rows, then run Model calculation to check the entered parameters.

How do I run a snapshot calculation in PIPE?
After drawing the system and entering its data, open Model calculation, select No optimization and click Calculate. Review Calculation log, Calculation results and Profile. Save calculation cases to compare them on Results comparison.
Read more:
Where do I configure the forecast period in PIPE?
Use Forecast period to create forecast steps and specify each step's start, end and duration. Open Model calculation and use Forecast calculation to select networks and run the forecast.
Read more:
Where do I work with integrated models in SOLVER?
The SOLVER Integrated Model workspace contains three areas. Use the Object navigator to select model objects, filter them by type, search by name and sort the list before working with their parameters.
Read more:
How do I run a baseline production-system forecast in SOLVER?
Open Model calculation, go to Forecast calculation, select No optimization and click Calculate. For wells linked to MBAL models, the initial forecast reservoir pressure follows the first forecast step specified in the MBAL reservoir model.
Read more:
How do I run methanol optimisation in SOLVER?
Add an inhibitor source or a well with inhibitor. For a source, select Inhibitor flow rate, enter the solution rate, concentration and temperature, then add Maximum Inhibitor Rate and enable Inhibitor Rate Selection. For a well, also enable methanol injection in General information. Select Methanol optimization and the network in Model calculation, then click Calculate.
Read more:
Where are the SOLVER model calculation controls described?
Open Model calculation in the upper-right corner to select networks and the calculation mode, including No optimization, constraints, Rule Based, Choke dP selection or Methanol optimization. Review the output on Calculation results, Profile and Calculation log; Forecast calculation provides the corresponding forecast controls.

How do I create a script in SERVER?
Use the script-creation example to learn how scripts are prepared in the SERVER module. Follow the example together with the SERVER module overview.
Read more:
How do I import libraries and packages in SERVER?
SERVER supports datetime, time, math, enum, numpy, selected scipy functions, pandas DataFrame, OisIpmLib and OisIpmUtils. OisIpmLib classes and functions are available implicitly, numpy is exposed as np, and scipy provides minimize and curve_fit. OisIpmUtils provides helpers for working with Excel files.
Read more:
How can I discover and use SERVER commands?
Use code completion in the SERVER script editor to explore available objects and methods. Follow the script writing example to import libraries, read and modify a model, save changes, and run the script with Run or Ctrl+R. Any user can read a stored model, create a new model, or start editing a model that nobody else is editing. Only the user editing a model can read its pending edits, write changes to that editing session, and finish or cancel editing. Other users continue to see the stored version until editing is finished with saving. The same access rules apply to calculation results and logs.

How do I call an external API from SERVER?
The documented workflow obtains an access token, authorises requests with that token, retrieves projects from ipm/projects, and runs a script through ipm/projects/{projectId}/python/start. The guide includes deployment-specific token and gateway URLs; use the addresses configured for your environment.
