Reservoir Description and Dynamics
Robert Barba brings more than 4 decades of expertise in the petroleum industry, specializing as an openhole wireline engineer, petrophysicist, product development manager, and completion optimization advisor. His work emphasizes the integration of petrophysics with completion and reservoir engineering to enhance well recovery. With a wealth of knowledge in both conventional and shale reservoirs, Barba earned the 2018 SPE Southwest North America Regional Formation Evaluation Award. As an SPE Distinguished Lecturer (1995โ1996), he shared insights on optimizing completion designs through petrophysical and reservoir engineering inputs and was again nominated for the 2024โ2025 DL season. A recognized authority on refrac candidate selection and best practices, Barba developed techniques for evaluating well performance that have been used on over 5,000 wells. Recently, he focused on refrac reorientation and parent-child issues facing the unconventional sector, contributing significantly to the field's literature.

Brazilian independent Enauta has agreed to sell a 20% participating interest in the BS-4 concession, which includes the Atlanta and Oliva fields, to Westlawn Americas Offshore (WAO) for 301.7 million. WAO is a portfolio company of Westlawn Group LLC and owns various interests in the Gulf of Mexico offshore basins. Enauta said the sale amount will be paid at closing and subject to adjustments related to the net cash flow with investments for the delivery of Atlanta and Oliva generated between the effective date of 1 November 2023 and the transaction closing date. As part of the transaction, 75 million will be paid over the coming 60 days as a loan to be deducted from the amount paid at closing. The transaction also includes an option to sell a 20% stake in Atlanta Field B.V. (AFBV) for 65 million in 2024 upon agreement.

Earlier this year, GA Drilling and ZeroGeo Energy unveiled plans for a 12-MW geothermal power plant in Lower Saxony, Germany, named "Projekt Thermo." This partnership, formalized by a memorandum of understanding in February, aims to lead to a series of geothermal projects across Europe. ZeroGeo, a Swiss-based energy company founded in 2021, will be the project's operator having secured two geothermal exploration permits in Lower Saxony where it completed a geophysical campaign in early 2023. Notably, this campaign featured a 5000-kmยฒ aerial full tensor gravity gradiometry survey, marking its first application in Europe for geothermal prospecting. Projekt Thermo will be the first commercial project for ZeroGeo and its partner GA Drilling which will be debuting its "anchorbit" technology to provide enhanced drilling stability.
Exploiting the potential of sunlight, wind, and water not only provides a clean substitute for conventional energy but also unlocks opportunities for innovative technologies and methodologies. It becomes clear that the route to a more environmentally friendly future necessitates a shared commitment to adopting and progressing renewable energy solutions. Through ongoing research, advancements in technology, and widespread implementation, it is time to mark a transformative period for a cleaner and more environmentally conscious world.

Effective Cementing Solutions for CCS Wells is a half-day Training Course that will focus on the challenges of completing and cementing Carbon Capture and Storage wells. For CCS wells, the design should start with the completion size required to achieve the desired CO2 injection rate. Dual containment is essential; the second barrier must not only be designed for the corrosive environment but the second barrier and its associated equipment must be periodically inspected or tested. The differences between CCS wells and conventional oil and gas wells require a different approach to well design. If CCS wells were to be designed using established methods for oil and gas, the wells might fail to maintain integrity to prevent undetected migration of stored CO2.

The SEG Wiki's main mission is to supply scientific materials to the geoscience community and the public through online books, tutorials, geoscience articles, and biographies of key geoscientists. SEG's two best-selling books are provided open and free of charge on the SEG Wiki: Encyclopedic Dictionary of Applied Geophysics and Seismic Data Analysis. The Knowledge tree is the gateway to a collection of scientific, mathematic, geophysical, and geological information for the student and professional. In addition, bi-monthly geophysical tutorials published in The Leading Edge are made available on the wiki. The wiki captures the history of the exploration geophysics discipline through hundreds of biographies that also highlights important contributions from the founding members of SEG and women in geoscience.

The principal objective is at 3000 m with a stacking velocity of 3000 m/s. What frequencies should be covered by a linear sweep? The vibroseis method employs a vibrator to impart to the ground a long train of harmonic signals of varying frequency. The vibrator consists of a piston pressing against a steel plate which is held against the ground by the weight of the vehicle. For the usual linear sweep, the vibrator, which is actuated hydraulically, exerts a pressure Failed to parse (SVG with PNG fallback (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.")
