Production logging test in horizontal wells

Abstract

Horizontal drilling technology has significantly influenced the industry's approach to the development and recovery of hydrocarbons. Advances in drilling technology have led to improved well productivity, increased drainage areas, especially in low permeability reservoirs. These day companies adopted an approach that has assigned a high priority to monitoring horizontal wells in order to maximize benefits. The testing and logging programs are aimed to assess the flow profile of the horizontal wells, optimize well production rates and plan future production and workover strategies. For this reason development of new methods and technologies has become crucial. This paper covers peculiarities of production logging test techniques used in horizontal wells. This includes technological as well as technical innovations based on deeper understanding of the phenomena through detailed research of this area. W pracy przedstawiono specyfikę technik rejestrowania produktywności otworów horyzontalnych. Omówiono technologiczne oraz techniczne innowacje oparte na głębszym zrozumieniu zjawisk, dzięki przeprowadzeniu szczegółowych badań tego obszaru.
