The COVID-19 pandemic naturally has affected SPE meetings, causing many to be rescheduled or postponed indefinitely, but SPE papers continue to be a crucial source of technical knowledge. The selected papers explore simple and complex innovative approaches toward reservoir characterization to work around the absence of certain data.

The authors describe a drilling-systems automation roadmap for a transition from humans to automation in the general drilling space.

Carbonate reservoirs require effective acid stimulation to improve well productivity. For long horizontal wells, a complicating factor has previously been the difficulty of controlling acid placement along the reservoir section. The Smart Liner concept uses a number of small holes spaced in such a way so as to distribute the acid evenly along the reservoir interval.

The authors describe an integrated multiscale data methodology involving machine-leaning tools applied to the Late Jurassic Upper Jubaila formation outcrop data.

The authors describe a logging-while-drilling nuclear-magnetic-resonance method applied in Bohai Bay, China, as an alternative to radioactive source-porosity measurements.

Exploratory, development well success in current onshore program.

Deal also includes commitment from Eni to drill four wells.

The study assessed the CO2 footprint and NO2 emissions for different drill-cuttings treatment alternatives. The values were then used to create an emissions calculator that can be applied to projects to clarify the actual potential for emissions reduction within the drilling-waste-management process.

The authors develop a collocated finite-volume method to study induced seismicity as a result of pore-pressure fluctuations.

The authors determine that economical and environmentally responsible solutions exist for fluid disposal during well-testing operations.
