The ultimate performance of fractured wells in tight reservoirs is affected severely by the interfering effects inside the fracture and interfractures.

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.

Horizontal- or complex-geometry-well construction projects are potentially good candidates to work out new contractual arrangements. Authorization to proceed with these projects is technically based, and measurable key variables can be defined.

This paper discusses the laboratory evaluation of potential high-pressure/high-temperature (HP/HT) drilling-fluid designs considered for a deep gas exploration well in Malaysia.

This paper discusses a rigid-setting-fluid (RSF) system that has proved successful for curing severe dynamic and static losses, pumping treatments through the drillstring bottomhole assembly (BHA) (no trip out required), because of its highly controllable fast-setting properties.

Mutual understanding and respect when universities collaborate with industry is crucial. A clear policy on harmonizing innovation and higher education should be created. However, caution must be taken not to have a one-size-fits-all approach.

This paper describes the first application of clay-free IEFs in the Norwegian continental shelf (NCS), with an emphasis on an impressively low and consistent ECD contribution.

Queensland, Australia, is currently host to a number of coal-seam-gas (CSG) to liquefied-natural-gas (LNG) projects under development.

Surface jet pumps (SJPs) are simple, low-cost, passive devices that use a high-pressure (HP) fluid as the motive force to boost the pressure of produced-gas and -liquid phases.

The incredibly tight rocks that are the source of North America’s gas renaissance are off limits in Germany and France. Though Maersk drilled the first multifractured horizontal well in the North Sea in 1987, some European countries are now banning operations that have occurred legally for decades.
