# Apps for Petro.ai

Apps built on Petro.ai use a common data model to give users a homogeneous data set to built workflows off of. Those built in-house by us are considered extensions of the platform. Apps can come in several forms:

  • WebApps are applications built on top of the Petro.ai web server. These are typically enabled at the Petron-level. See the Forecasting App
  • BI Extensions encompasses deep integrations between data analytics tools such as Spotfire and the Petro.ai platform. They utilize a common model and can often read/write to the data set. These are compiled extensions. See the Well Log tool.
  • Templates are analyses that are built off of the data model. They are configurable by the user. See the Gun Barrel analysis.
