  • Effect of Soaking on Shale Gas Well Performance

    Contains 3 Component(s), Includes Credits Includes a Live Web Event on 12/06/2021 at 10:00 AM (EST)

    This webinar presents field cases from different shale formations to investigate the effect of the soaking process on the well performance. Rate transient analysis (RTA) and decline curve analysis (DCA) were conducted on the production data before and after the soaking process to evaluate the change in the stimulated reservoir area (AC) and ultimate gas and water recovery (EURg, and EURw). An experimental study was conducted to investigate the change in the gas relative permeability and the water saturation distribution in the formation with the soaking process.

    During the fracturing treatment, a large volume of water is pumped with proppants into the well. Following the treatment, the well flows back. Only a small fraction of the injected water can be recovered. Over 75% of the injected volume, usually left unrecovered at the start of production that causes permeability damage and productivity impairment. Recently, in some shale formations, some operators have observed improved well performance after an extended shut-in period following the initial flow-back of a well that is called the soaking process. Contradict results were observed in the literature for the effect of the soaking process in the tight sand and shale gas formation through experimental and numerical simulation.

  • Deepwater Drilling

    Contains 2 Component(s), Includes Credits

    This Topic describes the equipment and technology that have made such advances possible.

    Description:

    The term "deepwater" has always been defined in terms of where offshore technology stood at a given moment. In the early 1960s, 500-foot water depths placed a practical limit on offshore drilling capabilities; by 2003, the water depth record had surpassed 10,000 feet. This Topic describes the equipment and technology that have made such advances possible. Starting with an overview of worldwide drilling activity, it looks at the characteristics of deepwater environments and the challenges they pose with respect to rig requirements and offshore project management. It goes on to discuss the systems, equipment and considerations involved in deepwater well planning, design and construction. It then examines some of the innovative solutions to deepwater drilling challenges, ranging from riserless drilling to dual activity operations. Finally, it presents several case studies to show how these solutions have been applied in the Gulf of Mexico, offshore eastern Canada and the North Sea.
