Irrespective of industry or sector, the objectives of innovation are productivity and performance improvement and cost reduction.

A new workflow technology has been launched that uses real-time logging-while-drilling (LWD) data and a new horizontal well-correlation technique to dynamically update a structural framework that can be used to geosteer an active drilling well.

The elliptical (conical) damage profile associated with horizontal wells is well-known, but review of industry-wide applications by different operators shows no corresponding uniform correlation between the damage profile and actual treatment volumes that have been applied.

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

The North American shale-gas boom has highlighted the differences that a few years and a few thousand miles can make.

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.

An experimental study of liquid loading of gas wells has been conducted with air/water flow in a 3-in. pipe at well deviations of 0, 15, and 30° from vertical.

One of the major challenges in fracturing low-permeability gas formations is the loss of well productivity caused by fluid entrapment in the matrix or fracture.

Offshore oil and gas fields exist along the continental shelf of every continent—even Antarctica.

There are considerable benefits to conducting rigless subsea well intervention from specialized monohull vessels.
