This case study by CNOOC and Halliburton highlights how enhanced multizone sand control treats eight unequal zones in one trip and reduces completion time by 60 hours in Bohai Bay, China.
US buyers are looking for extra shale inventory and added another $18 billion in purchases in October alone.
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.

Baker Hughes is developing a drill bit capable of auto-adjusting its depth-of-cut feature to handle dynamic drilling conditions. -
A real-time method is presented to predict impending stuck pipe with sufficient warning to prevent it. The new method uses automated analysis of real-time modeling coupled with real-time-data analysis.
-
Challenging environments such as unstable clay formations represent high operational risk when running tubulars after drilling is completed.
-
Larger-diameter coiled tubing recently has been used to perform millouts because of its improved set-down force and increased annular velocities for cleanout purposes. Service companies and operators have reduced the number of wiper trips when using larger-diameter CT, to save time and money.
-
This paper describes experiences, challenges, and approaches to solving the problems related to creating an advanced early kick-detection system suitable for floating mobile offshore drilling units.
-
The force required to drill through a rock is a direct test of its strength and stiffness. Developing a reliable measure of the properties of rock based on the force required to drill a long lateral is a large challenge.
-
Automated particle-size analyzers are something you will not see on most drilling rigs, but some think this outside-the-oil-field technology will play a big role in the future of the drilling sector.
-
Wellbore position is computed from survey measurements taken by a measurement-while-drilling (MWD) tool in the bottomhole assembly (BHA).
-
Cementing is central to the discussion of zonal isolation and well integrity.
