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 (1995–1996), he shared insights on optimizing completion designs through petrophysical and reservoir engineering inputs and was again nominated for the 2024–2025 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.

This one day training course focuses on the repair of channels, voids and leaks in a cemented wellbore. Poor cement coverage and lack of zonal isolation in the casing-borehole annulus often leads to production of undesired fluids and reduced hydrocarbons production, disposal problems, reservoir pressure decline, loss of hydrocarbon reserves and other problems. Objective of the course is to evaluate and discuss various technologies used to repair wellbore communication paths due to wellbore aging that can develop allowing fluid to migrate from the high pressure downhole strata through leakage paths in the cement containment. Poor cement coverage and inadequate zonal isolation affects nearly every aspect of a well during its life. This course will give participants a better understanding of some critical well safety and integrity issues and methods to repair wells that have reliability issues, including sustained casing pressure (SCP).
This course examines methods for detecting fluid channels, voids and leaks, and how to repair them. It also covers the logging tools and technologies use to evaluate the integrity of the cement prior to initial completion or anytime during the life of the well. The first day of class is dedicated to evaluating cement and the second day to repairs. Poor cement coverage affects nearly every aspect of a well. This course will give you a better understanding of some critical well safety and integrity issues.
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.
Embracing a mission of connecting the world of applied geophysics,the Society of Exploration Geophysicists (SEG) is a not-for-profit organization supporting more than 11,000 members from 126 countries. SEG's long-standing tradition of excellence in education, professional development, new business generation, and engagement cultivates a unique community platform that encourages collaboration and thought leadership for the advancement of geophysical science around the world. Headquartered in Houston, TX, SEG has a business office in Tulsa, OK and regional offices in Dubai, UAE and Beijing, China. SEG is a global society that fosters the expert and ethical practice of geophysics in the exploration and development of natural resources, in characterizing the near-surface, and in mitigating earth hazards by inspiring the geophysicists of today and tomorrow.
