Borhene B.
As a Senior Geophysicist with over 12 years of experience in the oil and gas industry, I specialize in seismic interpretation, with focus on reservoir characterization. My expertise covers the entire seismic workflow, from acquisition to processing and interpretation, ensuring that the subsurface is thoroughly understood to guide exploration and development decisions. I have worked extensively with both 2D and 3D seismic data, integrating it with well logs and other geophysical datasets to identify and characterize hydrocarbon reservoirs using advanced geophysical software tools for seismic data analysis, such as Petrel, DecisionSpace, or OpendTect, enabling accurate subsurface mapping and risk assessment. My experience in reservoir characterization allows me to provide detailed insights into the distribution and properties of reservoirs, which is critical for assessing their potential productivity. I am also skilled in seismic acquisition and processing, ensuring that the data quality meets the highest standards for interpretation. My knowledge of AVO and quantitative interpretation (QI) has been instrumental in de-risking prospects by assessing fluid and lithology changes, helping to differentiate between hydrocarbon-bearing and water-bearing zones. Throughout my career, I have collaborated with multidisciplinary teams, including geologists, reservoir engineers, and drilling teams, to optimize exploration strategies and enhance field development. My ability to deliver accurate subsurface models and communicate findings effectively to stakeholders has been key in supporting data-driven decision-making in complex geological environments. I am dedicated to staying at the forefront of geophysical technologies to ensure high-impact, innovative contributions to the projects I work on.
