Geophysics

• The Geophysics core is a new core that leverages the Petrel E&P platform and provides a toolset tailored for geophysics workflows. It enables companies to undertake geophysical map-based approaches, covering seismic interpretation, well correlation, seismic well tie, seismic attribute computation, and structural framework construction. There is no geocellular modeling capability in this core.
• Horizon interpretation can now be linked with stratigraphy, incorporates more metadata, and has improved rendering for large interpretation displays. It also incorporates a usability enhancement to switch interpretation modes quickly.
• Seismic overlay in the interpretation now allows you to apply a user-defined opacity function for the displayed foreground vintage.
• The Mixer tool is an intuitive and interactive visualization tool for comparing and evaluating multiple seismic cubes simultaneously and synchronously with three types of workflows: flip/roll, RGB/CMY blending, and masking.
• A generalized spectral decomposition volume attribute provides a hybrid method of existing short-time Fourier transform (STFT) and continuous wavelet transform (CWT) techniques in the industry, allowing the interpreter to better control the vertical and the frequency resolution simultaneously.
• Interactive mesh editing allows the interactive editing of any mesh body (for example, salt) using push/pull and smooth/refined functions for more accurate interpretation of complex shapes.
• Velocity modeling performance and robustness has been significantly improved, allowing for simple velocity model building and faster depth conversion or advanced velocity modeling including average or interval velocity cubes.
• Interactive bulk shift has been added to the seismic well tie process, as well as continuous alignment for accurate and fast ties.
• Multiwell extended white wavelet extraction is available to extract wavelets from multiple wells at the same time.
• Litho classification is now part of the Petrel Quantitative Interpretation module and is used to generate a lithocube from a seismic inversion result, including probability of hydrocarbon or rock typing.
• QI crossplot has been enhanced to be able to incorporate more data types, such as horizon attributes and new PDF curves for lithology classification.

Geology & modeling

• A new well model has been incorporated to support complex trajectory types for well surveys and plans as well as sidetrack or lateral wells.
• Well correlation ghost curves allow you to create ghost curves for a single curve, for a single track with multiple logs, and for multiple tracks.
• Geopolygon is a new data object for representing closed polygon data with holes and attributes for cultural data and prospect risk evaluation maps.
• Volumes in place can now be calculated from the volume-based zone model of the structural framework. 
• Isochore/isopachs can be calculated directly from the horizon of the structural framework.
• Stratigraphic layering allows a better generation of layers during the structural modeling process by using the implicit function from the volume-based modeling structural framework. It is specifically useful in the case of erosion and discontinuities.
• Declustering options allow you to correct for sampling bias in either facies proportions and histograms or the petrophysical property distribution caused by horizontal and clustered wells.
• Weighting option in scale-up well logs allows upscaling using a continuous log curve as weight.
• Well list/saved search supports well data management and control visualization.

Petroleum engineering (reservoir and production engineering) 

• Production forecasting using decline curves analysis (DCA) can be conducted for selected phases of interest, noisy data can be excluded, and analysis parameters can be manipulated for best fit. Supported analysis methods include Arps, stretched exponential, Duong, and power law (Petrel 2015.2). 
• Reservoir calibration using industry-standard and Schlumberger patented rate transient analysis techniques. 
• Production interpretation, well deliverability, production analytics, and OFM data connector are now included with the Reservoir Engineering Core, Shale Core, and Combined Core licenses. 
• Grids for initial condition sets can be generated in two ways: the initial conditions process or the initialize from maps process. The initial condition process is now separated from the process for making a fluid model.
• Well search based on production attributes in the Studio  environment enables you to find and select focus wells based on KPIs, for example “time on production,” “total gas recovery till date,” etc. 
• Flexible units control for reservoir engineering means that you can define simulation input data in a unit system that is different from that used in other domains by independently setting or customizing the unit system in supported dialog boxes and spreadsheets.
• Improvements in the performance of simulation export to the INTERSECT high-resolution reservoir simulator have been made.
• 3D results analysis is facilitated by one-button-click generation of multiple 3D windows, based on analysis purpose and based on case.
• The use of repeat formation tester and production logging data in an objective function has been simplified.
