The Techlog Fluid Contact module allows the input of multiple zonation schemes in which to incorporate information from geology (layering, structure, faults from a 3D Earth model, etc.), reservoir engineering (initialization regions from a simulator), and petrophysics (fluid codes, net reservoir intervals, fluid levels, and gradients from the Formation Pressure module).
The depth data of these multiple inputs is resolved in measured depth and TVD (true vertical depth). This can be within a single wellbore or across multiple wellbores, to identify compartments within the reservoir as seen through well data. A new Techlog data entity has also been created: 'fluid contact related to a hydraulic zone'. This data entity allows the management of multiple contacts within wells, for example hydraulic zones may be used explicitly to control calculation workflows in the Quanti and Formation Pressure modules.
A new dock window tool, the Contact Manager, improves the visualizing and editing of one or more contacts within a project. The Contact Manager allows users to display contacts in plots for visual comparison across wells and insert fluid levels in stratigraphic zonations for fluid-specific calculations such as summaries.
The main Fluid Control output is a table of minimum, most likely, and maximum depths of each fluid contact between pairs of fluids. Information for each “initialization region” or reservoir compartment is separately reported for ease of transfer into external models. The output contact dataset is ready to be transferred directly to the Petrel E&P software platform using the related plug-in.
