P2 Gas Material Balance


The P2 Gas Material Balance application allows you to quickly import or link to gas well data from leading data sources and calculate gas material reserves for single or multi-well pools. Results may be plotted or printed to any Windows compatible printer.


Reserves Management P2 Gas Material Balance


P2 Gas Material Balance current features enable users to:

  • Maintain a permanent and up-to-date database of all the production history and pressure data for your company wells
  • Use our integration with IHS Energy (AccuMap) and Divestco (GeoCarta or MSI Capture) mapping systems to automatically launch P2 Decline Analysis and pass the selected wells to them for viewing and analysis
  • Retrieve wells from within the database by location, field, pool and unit code and create well groups for future use
  • Interactively exclude single data points in a well on screen or add or remove wells from the multi-well pools during analysis
  • Quickly toggle between pool and individual well gas material balance plots
  • Highlight and view an individual well pressure history in a multi-well pool
  • Add new pressure analysis information into the P2 Gas Material Balance database as soon as it becomes available
  • Automatically calculate and display best-fit line on the P2 Gas Material Balance versus cumulative production graph
  • Define the pool recoverable reserves by specifying the abandonment pressure or a recovery pressure. For whichever one you choose, P2 Gas Material Balance calculates the other one
  • Use automatically imported government pool reservoir properties or create custom reservoir property dataset for gas material analysis calculations
  • Save as many as five user-defined best-fit lines in a Fit Menu and select any one to be current
  • View on-screen the production split of any well in the group for as many as five user-defined time periods
  • Plot as many as three production series on the pressure-time plot, including daily gas rate, cumulative gas production, or water-gas ratio
  • Data for all wells may be edited at any time
  • Open the Pressure Table report to view all the pressure data for the currently selected wells

Special Evaluation Features

P2 Gas Material Balance has a number of features that assist in performing a gas reserves evaluation. These key features are described below.

  • P2 Gas Material Balance alerts the user if the selected wells in a multi-well pool are from more than one pool and the reservoir gas properties or datum depths are different
  • If more than one pool is found, the user is asked to select which pool gas properties and datum elevation to use in the evaluation and P2 Gas Material Balance corrects all pressures to the defined datum depth
  • P2 Gas Material Balance allows the user to open the pressure versus time, P/Z versus cumulative production and the raw pressure data windows concurrently
  • P2 Gas Material Balance automatically looks for gas injection in all the selected wells and, if found, will adjust the cumulative production to be cumulative production less cumulative injection
  • The user is allowed to draw as many as five user-defined P/Z analyses on the material balance graph for any multi-well group. This feature allows the user to establish a range of gas reserves and select the most appropriate value

Sources of Data

Data may be input into P2 Gas Material Balance in the following ways:

  • Import production data using conventional export formats from P2 Energy Solutions, IHS Energy (AccuMap, International Petrodata, QC Data and Dwight’s US), Divestco, and geoLOGIC
  • Use GIS mapping systems to select wells for viewing and obtain the well information from transparent links to PPDM databases stored on internal computer networks
  • P2 Gas Material Balance contains a facility for directly inputting well pressure data, gas properties and monthly production data for the wells if an electronic source of data is not available
  • Corporate database users may wish to access their own production data. P2 Energy Solutions will work with these users to develop an appropriate interface for their specific environment

Well Selection

P2 Gas Material Balance contains a well selection window that allows the user to select wells from all wells in the database or any user-defined group of wells using a variety of well criterion. The search criteria includes:

  • Well field, pool unit or operator codes
  • Province/State
  • Primary product status
  • On-production date
  • Wells with temporary or permanent forecasts

The selected wells may then be saved as a group in the database for current or later use. During interpretation, individual wells may be added or removed from the group and P2 Gas Material Balance will automatically recalculate the cumulative production and gas reserves.


Reports and Plots

The user may print the material balance and pressure-time graphs of raw or analyzed data on any Windows compatible printer. Both of these graphs can be supplemented with additional user-defined headings, well lists and pressure data. The material balance graph can also be formatted to output the well production split information alone with the list of wells. The pressure table report can be printed or exported in *.csv or *.txt formats.
