WellSpring's Shale gas workflow helps companies model complex development plans quickly and thoroughly so they can spend time on testing ideas and strategies instead of developing and maintaining massive spreadsheets. Analyzing the economics of a shale gas, or other unconventional resource play, requires a number of iterations looking at well capability, number of wells, number and availability of drilling and completion rigs, facility sizing, and timing. Using WellSpring, all of these variables can be easily modified to quickly look at the many permutations to the problem.
WellSpring’s visual interface helps simplify the analysis of complex problems. By allowing you to view your wells, pads, rigs and facilities, along with your gathering system, WellSpring lets you see your development plan unfold.
For a Shale Gas development, you can build your gathering system infrastructure specifying the limits on any sales lines, water disposal infrastructure, or compressors. You can specify when the capacities of these facilities change over time and schedule drilling to maintain capacity, allowing for quick and accurate comparison of many different development pacing alternatives. You can also put in the existing production from your current wells, together with a forecast for the future production to give you a complete plan.
Finding the Optimum Development Pace
By making it easy to modify rig schedules, well forecasts, facility limits or expansions, WellSpring enables you to quickly evaluate alternative development options. WellSpring allows you to focus on the business decisions for all your projects - CBM, Shale gas, SAGD, CSS, or conventional projects.
WellSpring has the ability to automatically evaluate development scenarios based on the flow network’s limitations such as:
- How many rigs do I need drilling to maintain my water injection at capacity?
- When do I need to expand my water handling capacity to keep up with my various drilling options?
- When do I need to recomplete wells to meet delivery contract obligations?
WellSpring visually and numerically compares the options with both volume and full economic comparisons of your various scenarios. By allowing the detailed rig scheduling to be combined with the flow network and economics, decision evaluation cycles are drastically reduced. This allows companies to make better decisions with fewer people.
Shale gas plays typically require large drilling programs, and managing 1000’s of wells in a drilling program can be tedious. WellSpring is being used by companies to manage +10,000 well drilling programs in a single asset. WellSpring has intuitive interfaces to model pad based drilling and completion timing, limited access issues, timing and per rig costs. WellSpring also has complex performance and efficiency improvement modeling functions.
Existing Production and Economics
Wellspring includes comprehensive decline analysis and production forecasting system with fully integrated US and international economics modeling. The decline allows for quick “best fit” analysis of existing production, including the ability to infill drill using quick rig scheduling and ensure facility limitations will not have an impact in future expansions
WellSpring’s detailed economic modeling, including US, Canadian and International fiscal models, allow you to quickly evaluate the economic impact of development options. The different options can be compared using differential consolidations. And WellSpring’s rich reporting and graphing tools help users to fully analyze the impacts of development changes.
Lifecycle Project Scheduling
WellSpring allows you to define a project schedule as a series of tasks over time that linked together through dependencies and are dependent on resource availability. This allows you to model a complete project from land acquisition through facility construction and detailed drilling schedules with rig availability. When any element changes, your project is instantly updated giving you an accurate picture of the timing and the value of your project.
This complete picture of the project provides a collaborative environment in which all team members can describe their project elements and see how changes in their aspect of the project impacts the other groups, such as facilities, marketing, drilling and reservoir.
The lifecycle modeling capability of WellSpring allows a proper economic analysis of projects ranging from small field development plans to large resource plays with complex infrastructure planning requirements. Forecasting the drilling schedule, capital budget and rate of return on a petroleum project is a rigorous task that WellSpring can make an easier process with better results.
Why use Enersight’s WellSpring for Shale Gas Planning?
For Shale gas, or unconventional gas projects in general, WellSpring provides a powerful development planning tool that allows you to visually model your gas gathering system, including any constraints.
