Drilling
Drillships Deepwater Asgard and Deepwater Atlas have fresh US Gulf Mexico campaigns upcoming that will earn the driller more than $500,000 per day.
This paper describes the technical challenges of drilling and running casing in superlaterals in the Vaca Muerta unconventional play.
As technology continue to evolve and reservoirs become more challenging to access, the drilling industry is further improving its efficiency and derisking operations through the use of artificial intelligence, lighter and stronger pipes, and sophisticated data analytics.

The authors of this paper describe a project in which Raleigh frequency-shift distributed strain sensing monitored during production in a far-field observation well was translated to an estimated pressure profile. -
Typically, oil and gas producing wells are abandoned toward the end of their life cycles with reservoir pressures depleted compared with the virgin pressures. Carbon capture and storage projects, however, present different operating conditions.

SponsoredWith more surface facilities and infrastructure in oil and gas fields, well casing integrity is becoming an even bigger challenge. This article sheds light on the optimum way to deal with the increasing casing integrity challenges in the Middle East through field monitoring and time-lapse casing-integrity and corrosion-inspection logging.

The well was spudded from the new Azeri Central East platform in the giant ACG field in the Caspian Sea.

This paper describes an 18-month intensive continuous improvement process between an operator, a rig contractor, and bottomhole-assembly (BHA) service providers aimed at reducing BHAs per well in two Oklahoma rigs.
-
This paper presents the study, resulting recommendations, and a proposed change in standard bottomhole-assembly configurations to reduce service-quality-compromising incidents and productive time lost from jar twistoffs.
-
This paper discusses a full-scale drilling test rig that allows comprehensive study of the influences of bit characteristics on high-frequency torsional oscillations (HFTO) for the first time.
-
As bottomhole-assembly and drill-bit design and operation have embraced new technologies such as artificial intelligence, new materials and manufacturing techniques, and improved design software, the industry continues to research methods of optimizing delivery and understanding of already globally used technologies.
-
Few oil and gas companies give data science projects the better part of a decade to prove out, but that’s just what this one did.
-
An estimated $35 billion in investment is expected to pour into geothermal projects in Kenya and Ethiopia through 2050.
