gohfer 9.0.1.6 GOHFER 3D - Multi-disciplinary, integrated geomechanical fracture simulator incorporating all the tools necessary for conventional and unconventional well completion design, analysis and optimization New GOHFER 3D 9.0 Features • Ability to add multiple wells, including vertical and horizontal, in the same project • F racture stress shadow interference between each fracture and stage on each well • Can simulate : Multi - layer completions / Zipper - fracs / Offset D epletion E ffects • Full 3D geo - mechanical earth model input (from Petrel GSLIB file) • Optional input of 2D surface map with reference well logs • Geo - steering of laterals and engineered completions • Full processing of log or “core” from 3D earth model Well Construction • Can define coordinate system and site / well locations • Ability to convert latitude and longitude to state plane • Ability to lookup state plane zone by county • Ability to display location on map • Ability to view surface map (and layers) of all wells • Removed option to Add Reference Survey and L AS option in Well Construction • Removed option to Convert Treatment LAS to Reference LAS option in Well Construction • New Project Type options: o Single Vertical Treatmen t Well / No Transverse Fractures o Multiple Treatment Wells / Enable Transverse Fractures • Wellbore string inputs now accessible from each individual well under Well Construction or from the well tab under Geologic Section • Disabled MD/TVD mode in survey. MD/INC/AZI required. • Added GSLIB viewer • Added link to State Plane and UTM conversion tools • Fixed an issue with r ight click paste in Well Construction/Well Locations table Log Processing • Reference LAS input data options: o Reference well logs only (no geologic model available) o Reference well logs and core sample(s) taken from an imported geologic model o Core sample(s) taken from an imported geologic model (no reference well logs) • M oved PORE_P_LAS and STRESS_TOTAL_LAS to bot tom of PORE_P_SRC and STRESS_TOTAL_SRC so they will no longer be automatically used if they are mapped. To use these curves, the user must manually move these to the top of the list. • Moved LAS Assignments to the top in LAS Processing /GOHFER Curves column • Added a change to prevent user from shifting or scaling PORE_P_SRC or PORE_P_EST • Added the following new LAS curves: o AVH / PHIS / YMELAS / DTCYME / NETPAYEST / SWEST / BIOTS_VPHIE Grid Setup • Simulation mode options: o Transverse Only o Transverse + Longitudinal o Longitudinal + Transverse • Default node size now set to 5 ft • Further separated and r eorganized grids into separate folders (Grid properties and Intermediate Calculations) • Tabs for each wellbore • Ability to see multiple wells in transverse grid t abs • Added Map view option to g ri d setup • Ability to add faults in map view • Ability to view geologic model scatter plot in map view • Added the ability to change the map layer in Treatment Configurations/Wellbore tab • Addressed issues with renaming designs affecting stage shadowing • Ability to export grid data to geologic model in GSLIB format • A dded a Fit to Ruler option in the Engine output for Node Width • Removed V/H Factor from the PZS and PHOLD grid. Now handled by the AVH grid. • Renamed Baseline Conductiv ity output grid to Effective Conductivity • Each simulation now generates a triplets file in gslib format (*.triplets.gslib) in addition to the triplets.csv file • Added the o ption to select which curves to export to the triplets file • Added wellbore stability calculations and ability to export the data Engine Output Viewer • ALL simulations are now asymmetrical. Symmetrical fractures are no longer simulated. • Fixed an issue metric projects that display ed the perf MD at the bottom of the screen in oilfield units instead of metric units • Fixed an issue with the pipe friction calculation for BHP in the engine • Fixed an issue with the Ruler for proppant cutoff length not working on vertical well projects
