The document describes an Exploration Drilling Schedule Optimization System (EDSOS) that has two main components: 1) a Drilling Scheduler that allows users to manually drag and drop wells into time slots and runs optimization scenarios based on constraints, and 2) a Task Tracker that monitors well planning, approval, drilling, and post-drilling activities. The system facilitates real-time impact analysis and optimization of the drilling schedule to meet exploration objectives like replacing oil production and increasing gas reserves.

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 OPTIMIZATION ENGINE
