Optimization
1. Manually drag and drop wells into well slots
2. Optimizer will run scenarios based on constraints in metrics

Exploration Well Schedule Optimizer (EWSO)
EXPLORATION OBJECTIVES• Replace Oil Production
• Increase Gas Reserves
OPTIMIZATION and IMPACT ANALYSIS
• Optimize the Drilling Schedule based on proposed changes to one or more Metrics.
• Analyze the impact of proposed changes to Well Slot Allocation and/or Metrics.
• Most metrics are variable and EWSO must have the capability to run sensitivities to analyze the impact of various possibilities.
• Some of the Metrics are fixed (e.g. Budgets and Rig Years) and therefore, EWSO must have the capability to display the impact of proposed changes on them.
will facilitate real-time Impact Analysis and Optimization
to meet Objectives

Oil Volume* Onshore
Region 1 Region 2 Region 3
Offshore Region 1 Region 2 Region 3
Stratigraphic split Exploration by regions if required
Unconventional resources Exploration by regions if required

BUSINESS RULES FOR OBJECTIVES AND METRICS
Well Slot Allocation geographic limitations for rigs gas versus oil rig and oil versus gas rig change maximum limit of mobilization distances and costs activity distribution between divisions and oil and gas will allow exploration wells to be moved, but not development
wells will allow exploration wells to be slotted between development
wells in this case, approval will be required from Production on moves involving
changes in development well schedule
will not allow wells to be moved into the 4-6 month window prior to spud
will not allow wells to be moved into 6 month window prior to spud unless staking and/or site preparation has been initiated/approved
Portfolio Profile risk profile of active wells in Drilling Schedule (POS and
objectives) adherence to Exploration Strategies (focus areas)
must be built into EWSO to ensure that proposed changes are technically feasible,
and in compliance with Business and Operating Plans,
as well as Aramco policies and procedures
