Drilling
This paper presents the application of degradable particulate-diverter technology to improve oil production by effectively diverting stimulation treatment fluids away from high-water-cut, high-permeability, high-temperature producing intervals or zones.
This paper presents the methodology for developing drill-in organophilic clay-free invert-emulsion-fluid technology that enhances well production through fundamental geological studies and fluid testing.
This paper presents the large-scale deployment and operational integration of an advanced, automated rheometer in the Ghawar gas field, one of the world’s most prolific and technically complex hydrocarbon developments.

A surface-based torque and tension sub (TTS) was used to perform measurements while drilling several extended-reach horizontal wells. -
The drilling-systems-automation roadmap (DSA-R) initiative is a cross-industry effort launched in June 2013 to help accelerate the adoption of advancements in drilling-systems automation (DSA) for both onshore and offshore wells.

Well control training programs for deepwater drillers and key rig personnel are undergoing a major overhaul that has been years in the making.
-
After the 2010 subsea blowout of the Macondo well that resulted in 11 deaths and the worst oil spill in US history, early kick detection technology found itself at the top of the wish list for regulators and offshore companies seeking to avoid similar accidents.
-
Technology developers are working on a new ultrasonic flowmeter for drilling fluids aimed at obtaining better measurements than current systems with far fewer disruptions to rig systems.
-
Researchers at the University of Texas at Austin (UT) have set an audacious goal to halve the time, cost, and number of rig personnel required for drilling every type of well, from unconventional shale to ultradeepwater.
