In Mexico, the development fields of the northeastern marine region have complex geological structures, which have formations with thicknesses that limit well directional operations, especially those related to the construction of high-angle curves in the reservoir.
Derived from the current challenges and demands in well drilling, the requirement of a greater area of contact in the reservoir to increase the oil production, causing the drilling of wells in a high angle and forcing the use of various technologies to minimize drilling risks, turning them into methods for optimization.
This technical document shows the application of resistivity technology close to the bit, providing added value to geological control and monitoring during drilling, allowing the collection of information as a key point for critical casing points.
When drilling of a horizontal well, the problem of performing high angle curves in formations with risk of generating non-productive times is addressed, as well as the reduced thickness in certain areas of the reservoir are limiting for the construction of the horizontal section. Performing the correct casing point at the top of the reservoir allows the anhydrite zone to be isolated, which represents a potential risk during drilling.
As a result of real-time monitoring of the resistivity at the bit and the interpretation of structural geological information from correlation wells, minimization of the uncertainty to casing point in the desired formation was achieved, providing a wide vertical thickness margin, to achieve planned trajectory and position the well within the desired rock unit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
