This course covers conventional and unconventional reservoirs.
This course is intended to enhance well ideas, particularly horizontal and multilateral wells, which have become a prominent element of new field development and redevelopment options. When employed properly, they may significantly increase the economic viability of field development activities for both unconventional and conventional resources. This course emphasises the complex, multidisciplinary considerations involved in advanced well projects. The applications and advantages of horizontal and multilateral wells are discussed. The process of screening and selecting candidates takes into account geology, reservoir, and production factors, as well as drilling and completion restrictions. Methods for predicting well performance and recovery from horizontal and multilateral wells are described, using inflow and wellbore flow performance for both individual and multilateral wells. Well completion alternatives and their effects on well performance for horizontal and multilateral wells are summarised. The effectiveness of well stimulation (multistage hydraulic fracturing and matrix acidization) is tested. Economic and risk analyses are also offered, along with a variety of case studies that demonstrate the performance and advantages of horizontal wells, as well as the components of risk and uncertainty during the original design stage.
