Specific Responsibilities
The Senior Petrophysicist will be responsible for analyzing and interpreting petrophysical data to provide valuable insights and recommendations for optimizing oil and gas reservoir development and evaluating exploration opportunities. They will collaborate with multidisciplinary teams to integrate petrophysical data with geological and geophysical information, contributing to and leading reservoir characterization and modeling efforts. The Senior Petrophysicist identifies and uses advanced petrophysical techniques to fully characterize the subsurface and reduce the petrophysical uncertainty in the reservoir characterization. They will provide support for drilling and completion operations and seismic rock physics analysis when needed with minimal support. Additionally, they will oversee the well log data acquisition and quality control, as well as providing technical guidance and mentorship to junior geoscientists. Strong analytical, problem-solving, and communication skills are essential for success in this role. This role will be primarily responsible for the following: • Support logging/coring operations, reservoir studies, and performance evaluations focusing on efforts to optimize the development of reservoir operations and recovery, including carbonate and unconventional reservoirs by working within cross-functional teams. • Perform advanced petrophysical analyses of unconventional and conventional reservoirs incorporating log, core and other relevant data. • Provide inputs for volumetric assessment and in place estimation with associated uncertainty. • Share best practices knowledge for petrophysical applications and evaluation processes with the asset teams and management. • Utilizes advanced petrophysical techniques and broad petrophysical knowledge of complex reservoir systems to conduct analyses and studies. • Lead all aspects of open and cased hole log acquisition, application, interpretation and advanced core analysis. • Provide recommendations for well design, mud weight estimation, target identification, and completion optimization as needed. • Share best practice knowledge for petrophysics with junior staff, management, and other non-petrophysicists. Present and lead training sessions when possible. • Participate and lead multidisciplinary projects and present the technical aspects of this work to a diverse audience of technical staff and leadership. Qualifications & Experience
The successful candidate will have the following qualifications and experience: • BS in Geology, Geophysics, or Engineering, and relevant experience (MS preferred but not required) • 8+ years of relevant E&P company experience • Possess knowledge of major petrophysical software packages applied in the industry for well and reservoir interpretation. • Must be current with the latest industry tools and petrophysical interpretation techniques working primarily with clastic reservoir systems. • Ability to design, manage, and interpret log and core data acquisition programs. • Familiarity with advanced methods of post core retrieval handling and analysis techniques. • Demonstrated ability to design logging programs in complex reservoir systems, maximizing data acquisition. • Advanced knowledge of all the modules in the petrophysical software.
