Mekers Offshore, a Zhejiang-based company, launched its first in a series of liftboats at Shanghai Bestway Dajin Heavy Industries yard in Jiangsu, China.

The Pugang gas field, one of the biggest inland gas discoveries of the last decade in China, has hydrogen sulfide (H2S) concentrations as high as 10%, making surface- and downhole-facilities design and execution challenging.

Nine horizontal wells, including one injector well, were drilled in a marginal oil field in Bohai Bay, China. Seismic inversion indicates that sand properties and connectivity vary dramatically across the field.

This paper discusses fracture stimulation in the first joint-venture shale-gas project with foreign companies in China.

While shale unproved technically recoverable resources have been identified around the world, development has been limited to North America.

Three observations have resulted from horizontal-well development in the Sulige tight gas field.

Natural-gas production from tight and shale-gas reservoirs will be increasingly important in China as the country shifts from coal-based energy to cleaner energy sources.

The Liwan gas reservoir was discovered in the South China Sea Block 29/26 in September 2006.
