REPOS (Reservoir Engineering Production Optimization System) is engineering information portal. It provides oil company wide web based environment for production engineers and management

REPOS (Reservoir Engineering Production Optimization System) is fully integrated, secure, web-based engineering solution for oil and gas industry. It provides engineers with suite of online tools to make reservoir study, analysis and optimization in quick and inexpensive manner

The portal provides an online access to the following field data:

  • Well Logs
  • Core analysis
  • Topographic and geologic maps
  • Reservoir Engineering maps
    • Bubble Pie maps
    • Block/Pattern indicator maps
    • Streamline maps
  • Geologic cross-sections
  • Correlation schemes
  • PVT data
  • Daily and monthly production data
  • Well history and well info
  • Workover history
  • Well test data

REPOS allows an engineer w/o software to be effective in time, decision-making and taking actions. One can go from field indicators and alarms down to well log, well history, current well production figures and workover status.

REPOS lets anyone who is authorized to connect to the newtwork and make an engineering study, analysis, evaluation etc. A team can be in preparation to waterflood review each quarter. Each team member can access customized indicators, tables, graphs, diagrams and be ready in time.

Some of field personnel enter workover data, updates on their smartphones then others access standardized daily indicators, alarms, field reports to be prepared before morning meeting starts.
