Abstract
Technology Focus The oil industry is moving every day to new frontiers to find and produce oil. The development of new fields is bringing different challenges. Several of these new frontier projects require the use of new technologies, thus further challenging project teams. Examples of such new frontiers are the Lower Tertiary in ultradeepwater Gulf of Mexico, the presalt in Brazil, and unconventional reservoirs. Drilling and completion are important activities in any field development and are also the most expensive, representing the biggest portion of the capital expenditures. Reducing the cost of wells, especially in ultradeep water, can make a big difference in the economics of a project. The number and placement of wells and the well trajectory and design are key factors for the success of a project and also require a significant investment in studies for knowledge and understanding of the reservoir, to make the correct selection for the wells to be drilled. One important aspect to be considered for well design is the appropriate technology to use to maximize recovery from the reservoir and reduce drilling costs. The papers featured this month are good examples of well design and use of new technology. Please enjoy your reading. Recommended additional reading at OnePetro: www.onepetro.org.
