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.

With the objective of increasing its production to 4.0 million BOPD, the Kuwait Oil Company (KOC) is developing its fields with optimum technology solutions.

This paper describes a comprehensive field study of eight horizontal wells deployed in the stacked Niobrara and Codell reservoirs in the Wattenberg Field (Denver-Julesburg Basin).

Tar mats are encountered in many Middle East carbonate reservoirs. In cases in which tar acts as a flow barrier between water and light oil, water injectors work most efficiently when placed horizontally immediately above the tar mat to maintain pressure support during production.

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