Planning future wells used to be a fragmented process: one tool for drawing pads (PowerPoint anyone?), another for modeling production, and yet another for capturing assumptions in spreadsheets. With our latest release, PetroAI eliminates that fragmentation entirely. Introducing Inventory Evaluation, a new set of features designed to help technical teams quickly design, simulate, and evaluate future development plans in a single, seamless workspace.
Whether you're optimizing a new pad, planning five years of development, or evaluating an acquisition, PetroAI lets you do it with speed, precision, and confidence.
At its core, the Inventory Evaluation module allows you to create custom inventory wells and run performance predictions using your existing PetroAI models. These wells aren’t just lines on a map, they’re fully configurable inputs you can adjust by interval, lateral length, spacing, relative landing, and completion timing. Each well is automatically integrated with your spatial, geologic, and performance context, which means every change is grounded in real data and structure.
You can create multiple scenarios for the same area, each with different assumptions or designs and compare them side-by-side without having to rerun builds from scratch. This capability opens the door to fast, structured experimentation. Want to see how 5 WPS in the WC_A compares to 4 WPS? Done. Curious how a pad would perform if you adjusted landing depth or changed the development sequence? You can build and evaluate that while sitting in a meeting.
You can draw wells directly on the map using the new well stick tools, or switch to the gunbarrel view to see and adjust well positions relative to structure grids and offset wells. Every well you draw appears in a dynamic summary table where values can be edited like a spreadsheet, filter, sort, or bulk-copy parameters just like you would in Excel. These three interfaces, map, gunbarrel, and table are always in sync, letting you move seamlessly between spatial planning and numerical refinement.
Each scenario operates independently within a batch. You can evaluate different spacing strategies, target intervals, or development sequences in parallel, each as a separate scenario within the same analysis. The process encourages iteration and exploration without slowing you down or requiring new data prep each time.
In the example shown above, we’ve designed a five-well pad targeting two intervals with varying relative landings. The layout was drawn directly on the map, refined in the gunbarrel viewer, and finalized in the table. From there, it was just a click to launch the evaluation and get performance predictions - all tied back to our subsurface model.
This represents a fundamental shift in how engineers evaluate inventory and plan development. Traditionally, teams have relied on two common approaches: selecting analog wells to generate type curves or conducting technical studies that produce EUR per foot maps, which are then applied to hand-drawn well sticks. Both workflows have clear limitations. Analog-based planning is quick but often too simplistic, failing to account for changes in geology, spacing, and completion design. On the other hand, custom studies can take weeks and require significant coordination across teams to build and apply, making it difficult to scale or repeat.
PetroAI replaces these disconnected steps with a single, integrated workflow. You can now draw wells directly on the map, configure their spacing, lateral length, interval, and completion date, and run performance predictions using the models already built into your PetroAI environment. There is no need to build separate maps, train new models, or rely on fixed type curves. The predictions are spatially aware, structure-consistent, and scenario-specific, all generated in real time.
It is not just a more efficient way to plan wells. It is a new way of working that brings together planning, modeling, and design in a unified workspace. For teams in planning, reservoir engineering, business development, or completions, PetroAI makes it possible to move from idea to analysis in minutes, not weeks.
