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.

Drilling long horizontal wellbores and completing wells with multistage fracturing are common practices in shale-play development.

Mixed carbonate-/sulfide-scale problems have been reported when water is produced from carbonate reservoirs. This study presents interactions of lead sulfide and zinc sulfide coprecipitating with calcite.

In the Eagle Ford, an integrated approach to engineering and operations was key to optimize performance and improve understanding of the area.

To accelerate learning, an operator deployed a real-time, closed-loop downhole automation system (DHAS) in conjunction with wired drillpipe in the 8¾-in.-hole section.

This paper presents the LCDSS and elaborates on the use of it in the preparation and training phase and the operational phase, including forecasting.

As systems automation becomes more widespread in drilling, simulators are required to plan, train rig crews, and monitor real-time operations.

This paper shows how automation reduces invisible lost time and allows drillers to focus on other activities while repetitive tasks are controlled by software.
