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.

For the development of the Dvalin high-pressure/high-temperature (HP/HT) gas field in the Norwegian Sea, a completion scheme using standalone screens is planned. -
Wells in deepwater reservoirs show significant rate decline with time as the result of various causes. A diagnostic tool for quantification of factors influencing well-productivity decline is presented in this paper.

Without exception, the featured articles reflect increased volumes of surface and downhole data that are being captured and analyzed to enable deep learning, improved efficiency, safety, and value.

The success of water-conformance operations often depends on clear identification of the water-production mechanism. Such assessment can be complicated significantly when formation damage is also occurring.
-
This case study discusses the methodology that underlies the successful determination of the depths and the radial locations in the outer casing strings of multiple leaks in an offshore well.
-
This paper focuses on the preparation for, and implementation of, well-control training, while highlighting the integration of people skills into curricula and what advantages operators and drilling contractors have obtained.

This paper describes the mobilization of a snubbing unit and blowout preventer (BOP) stack in the Middle East that enabled a well with an underground blowout and surface broaching to be brought under control within a short time.

SponsoredRunning casing to depth in long lateral sections is challenging, often costing operators a significant portion of pay zone at the toe of the well. This article highlights a technology that helped one operator add $120,000 to its incremental gas recovery.

Three appraisal wells drilled this year—GTA-1, Yakaar-2, and Orca-1—targeted nine hydrocarbon-bearing zones, encountering gas in high-quality reservoirs in all zones and yielding a combined 160 m of net pay.

Directional drilling and measurement-while-drilling technology has become so democratized in the Texas shale sector that no provider holds more than 8% of the market share.
