Key for Turon: an example of petrophysical modeling taking into account field development with horizontal wells

The Turon is known for its complex reservoir rock structures. Evaluation of reservoir properties is greatly complicated not only by its structure, but also by the lack of high-quality core material. In such conditions, building a high-quality petrophysical model is complicated. The authors presented the work on the development of a petrophysical model based on the data of modern special logging methods, which make it possible to approach the core data in terms of the amount of information received while conducting measurements in downhole conditions. A key feature of the model is the fact that the field will be drilled with horizontal wells using logging while drilling technologies. The obtained universal model is capable to assess the reservoir properties of complex rocks of the Turonian age, taking into account the influence of gas, lithology and laminated structure of the formation.
