NexTier Oilfield Solutions | Nov 2020 - Mar 2022

Staff Petroleum Engineer

● Provided completion optimization consulting services to NexTier clients. Services included plug/perf placement optimization, perforation scheme optimization, and root cause analysis of injectivity issues. ● List of Research and Development projects: o Max Clusters per Stage: Initiated, designed, and developed a workflow to determine the maximum allowable number of clusters per stage to minimize operational expenditures while maximizing EUR. o Fracturing Uniformity Index Model: Initiated, designed, and developed an injectivity simulator to model slurry distribution across stage perforation clusters as measured by Uniformity Index, diminishing the need for in-well permanent fiber diagnostics. o Plug Placement Optimization: Created a novel heuristic plug placement optimization algorithm to optimally place plugs along a lateral to minimize stage heterogeneity and promote uniform fracture propagation. Real Time and Playback Interpretation of Fracturing Pressure Data Methods and Devices for Hydraulic Fracturing Design and Optimization: A Modification to Zipper Frac SimulFrac Operations Optimization Based on Interwell Statistical Analysis of the Mechanical Specific Energy Logs o Perforation Placement: Created a novel perforation placement optimization algorithm to replace the legacy process, accelerating processing times from hours to minutes and enhancing flexibility by enabling the loss function to be user-determined. o MSE Log Generation: Digitally transformed the workflow to generate well mechanical specific energy profiles which improved profile consistency and slashed processing time by a factor of 20. ▪ Enhanced the data-cleaning process from partial to full automation. ▪ Created a novel hybrid mechanistic/statistical model to recreate pressure drop across drilling bottomhole assembly (BHA) from irregularly sampled pressure data. ▪ Devised a machine learning algorithm model that auto-detects rig state using drilling data. o Simulfrac Optimization: Co-developed a novel method (patent pending) to optimally pair horizontal wells on a pad during Simulfrac operations using well mechanical specific energy logs.
