Introduction

DECPRO allows you to create production history databases of your oil and gas wells, analyze performance and quickly forecast reserves by decline analysis. DECPRO will significantly reduce the time you have to spend evaluating reserves for acquisition or annual corporate reports and give you better results.

DECPRO Features

DECPRO's features enable the user to:

• Maintain a permanent and up to date database of all the production history data for your company wells.
  
• Use our integration with IHS Energy (AccuMap) and Divestco, (GeoCarta, or MSI Capture) mapping systems to automatically launch DECPRO and pass the selected wells for viewing and analysis.
  
• Import Westcan or Geo Webworks corporate data files that contain complete well lists, working interests, reserves estimates, and declines analysis into DECPRO.
  
• Use remote links to internal or external databases to automatically retrieve the most current production data (including daily field data) for your corporate wells.
  
• Create and store your own multi-well groups for reuse within the DECPRO database. Wells may be retrieved by well codes (location, field, pool and unit codes) as well as primary product, on-production date and by analysis status.
  
• Display your own customized linear, semi-log or log-log graphs of production data in imperial or metric units.
  
• Enter a well working interest and view graphs of company net production interest for single wells or well groups.
  
• Determine remaining reserves with best fit, or two point decline analysis techniques on screen. The best fit uses the standard least square curve fitting with the exponential, harmonic and hyperbolic equations.
  
• Generate your own multi-segment production forecasts using DECPRO's unique "Last Production" feature.
  
• Use the “Sum of Forecast” option on groups graphs to role-up individual well forecasts by reserve category.
  
• Derive oil and water production forecasts using a total fluid forecasts and liquid/liquid ratio curve such as oil cut, water cut or water-oil ratio.
  
• Work with multiple temporary decline analysis curves for one or more series and open the limits window to view the ultimate reserves defined by each option.
  
• View the declines and forecasts for the same series on any graph (i.e. cday oil series on the rate time or rate-cum graph).
  
• Save the production forecast for a production GOR, oil cut or water cut series as a one of twenty user-defined reserves categories.
  
• Use your saved production forecasts to generate a monthly production budget or a view a budget versus actual report.
  
• Normalize production for a group of wells to a common time zero and plot average production rates.
  
• Export production forecasts and ultimate reserves estimates to the Petro-Soft ERGO economic evaluation program.
  
• Annotate your decline curves with up to ten heading details.
  
• Batch print graphs or reports in either color or black and white.

Sources of Data

Data may be input into DECPRO in the following ways:

• Import production data using conventional export formats from Petro-Soft, 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 and/or remote data centres via dial-up, ISDN and fiber communication.
  
• Use the extended link capability of DECPRO to access daily field captured production information to view the most up to date production estimates.
  
• Create a comma-delimited file of monthly production data and working interests for your wells in any spreadsheet and import it to DECPRO. Ideal for evaluation of International wells.
  
• Create wells and input monthly production data directly. Data for all wells may be edited at any time.
  
• Corporate SQL Server database users may wish to access their own production data. Petro-Soft Systems will work with these users to develop an SQL interface for their specific environment.

Well Selection

DECPRO contains a “Well Selection” window, shown below, that allows you to select wells from all wells in the database or any user-defined group of wells using a variety of well criterion. The selected wells may then be saved as a group in the database for current or later use. 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

User Defined Displays

DECPRO enables the import of raw production, injection and disposal data. From the raw data series, DECPRO calculates approximately 60 other data series. The user may define up to 8 series to be used when displaying, printing or plotting a well graph. Each series can be assigned a color, line type and symbol type to uniquely distinguish the series. For reports, up to 12 series can be specified.
