POSITION SUMMARY

The Senior Reservoir Engineer provides subsurface evaluation and analysis to optimize the economic development, production, and recovery of Jonah Energy’s Permian Basin (Delaware) assets, and other assets as needed. The Sr. Reservoir Engineer may also perform exploration and A&D evaluations and assist in the corporate reserves and planning processes. This position collaborates closely with the broader development and operations teams in the Denver office, and reports to the Vice President of Reservoir Engineering & Geology.

ESSENTIAL RESPONSIBILITIES

• Drive innovation to extract value from conventional and unconventional assets.
• Guide development decisions for an active drilling program by addressing and incorporating input from the organization to prepare project justification in a timely fashion. Collaborate with the development and operations teams to evaluate and optimize recovery efficiency, completion design and well spacing.
• Develop/organize/contribute to internal efforts on data analytics, efficiency and quality control improvements, benchmarking, research, and new application development. Work with personnel to implement these solutions.
• Utilize multiple methods for evaluation, including decline-curve analysis, rate transient analysis, material balance, and numerical and analytical modeling. Understanding reservoir drive mechanisms, fluid characterization, and volumetric behavior of reservoirs and in-situ fluids is essential.
• Perform economic modeling and analysis of future production streams through cash flow analysis and the time value of money. Conduct quality control checks, verify accuracy of cash flows, and perform quality control of detailed production, pricing, and cost inputs. Prepare presentations and formal written reports.
• Manage and coordinate projects (reserves/resources, technical reservoir studies), including taking a lead role in projects involving complex situations and ensuring that timelines are met, and issues are resolved.
• Evaluate petroleum reservoir fluid properties, apply the principles of fluid flow through porous media, analyze data pertaining to rock properties, and estimate the recovery of hydrocarbons from subsurface reservoirs.
• Perform, review, and supervise reservoir studies to track reservoir performance as compared to predicted performance - develop optimal schedules and forecasts of individual reservoir deliverability.
• Perform evaluations for business development and acquisition opportunities.
• Assist in generation and review of inputs and outputs on third party and internal reserve reports.
• Collaborate with third party consultants to provide strategic guidance and technical support on regulatory applications (WOGCC, BLM, Texas Railroad etc.).
• Provide mentorship to staff throughout the development and operations teams.
