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.

This paper focuses on experimental methods quantifying water-based muds and investigating effects on particle bridging, filtrate invasion, and permeability. -
Well-control fluids were used during a routine overbalanced workover operation in an offshore well completed in high-permeability sandstone.
-
A challenge in many permeable, water-sensitive, subhydrostatic reservoirs is avoiding the loss of completion fluid when completing or working over wells.
-
This paper discusses the first multilateral well with a Level-4 junction combined with an inflow-control device (ICD) planned, designed, and drilled in the Upper Burgan reservoir of Raudhatain field, north Kuwait.

As with other MPD systems, SMD technology offers early detection of influxes (kicks) and minimizes downhole losses to weak subsurface formations.
-
The work presented combines a fundamental-physics approach with field data to identify the root cause of drilling failures in Paleocene and Eocene injectite-sand intervals.
-
Implementation of new technology can require that leadership and key team members be willing to step outside their comfort zones.
-
Large areas of the North Sea contain Cretaceous sediments, which form a massive hard layer of chalk that historically has presented a major drilling risk and expense to operators in the area.
-
Does formation-damage coreflooding give a good representation of damage that occurs downhole? For those of us who are actively involved in coreflooding, this is a common question to be asked.

The inventor of a new water-based drilling fluid believes the chemical process involved with his technology opens up natural fractures as drilling takes place to increase production in shale formations.
