Cementing is central to the discussion of zonal isolation and well integrity.

Saudi Aramco operates a large offshore oilfield development that has driven achievements in multilateral and extended-reach directional wells.

Eight of the world’s 10 longest wells have been drilled by ExxonMobil as operator of the Sakhalin-1 project in Russia.

Operators in the North Sea have been concerned about the ability of the cement sheath to maintain sealing integrity because of the increasing number of reported failures in mature wells. This paper presents results from a new laboratory setup to visualize the source of issues.

Many wells in the Cana-Woodford shale suffer from chronic sustained casing pressure (SCP) because of poor cement-sheath bonding.

In this study, detailed petrophysical and geological field models focusing on the middle and lower members of the Bakken Formation were developed.

Over the last couple of decades, we have seen a steady stream of “intelligent” innovations go from ideas to infancy to catalog solutions.

Carbon dioxide (CO2)/water foams are of interest for mobility control in CO2 enhanced oil recovery (EOR) and as energized fracture fluids or as hybrid processes that combine aspects of both processes.

A major oil company is progressing a portfolio of commercial-scale carbon-capture-and-storage (CCS) demonstration projects covering an array of technologies that target applications of relevance to the wider oil and gas industry.

Permanent downhole gauges (PDGs) can provide a continuous record of flow rate and pressure, which provides extensive information about the reservoir. In this work, a machine-learning framework based on PDG data was extended to two applications: multiwell testing and flow-rate reconstruction.
