Obstructed hemivagina and ipsilateral renal agenesis syndrome is a complex urogenital malformation usually presenting with obstructed menses and pelvic pain during female adolescence. The diagnosis can be established preoperatively with relative certainty by MRI or ultrasonography, and outcomes are usually satisfactory following surgical resection of the septal portion of the obstructed hemivagina. Such cases are best managed in referral centres with expertise in anatomical disorders of the female genital tract.

The Jurassic Marrat reservoir in Umm Roos field of West Kuwait (WK) is a low-permeability carbonate reservoir with heterogeneous petrophysical character that limited the predictability of reservoir properties and highly deviated development wells are preferred to maximize the exposure of the reservoir. However, there is an environmental risk and high operational cost when running radioactive-based porosity logging tools in such complex well profiles. To avoid that risk, Nuclear Magnetic Resonance (NMR) with conventional resistivity and gamma ray in a logging while drilling (LWD) program is proposed to achieve real-time formation evaluation and efficiently support well placement to maximize the reservoir contact. This paper presents the application of LWD-NMR as an alternative solution to evaluate reservoir properties as well as to land the highly deviated well successfully in the best reservoir sweet spots to achieve the maximum outcome for production.

Whole cores provide important and high-quality information about mineralogy, rock fabric and texture, porosity, saturations, geomechanical properties, facies stacking patterns, depositional environment, and fracture networks that often cannot be discerned with much certainty using other subsurface data sets. Here we present results from the detailed digital sedimentologic descriptions of three whole cores in West Kuwait that capture portions of the Middle/Upper Jurassic Najmah Formation, an important source rock and unconventional reservoir. The integration of detailed digital core descriptions with high-resolution XRF scanning of the cores, high-density routine core analysis and petrographic (thin section, epifluorescent, fracture-focused, and SEM) data, and a combination of XRD mineralogy and organic petrology provide the opportunity to evaluate multiple reservoir quality indicators across several depositional and diagenetic facies. Linking diagnostic indicators to specific facies (and providing constraints on the likely variation within) rather than simply associating these properties with broader stratigraphic intervals should enhance our ability to predict naturally inherent variations in the formation which will improve lateral well placement and completions strategies. It is anticipated that the data gathered, and the interpretations made from it will be used to design and alter the development and completion strategies across the asset to increase production and reduce risk.

Najmah-Sargelu formations are unconventional reservoirs in West Kuwait in deep section of Kra Al Maru field. Various options were introduced to perform a petrophysical characterization of these unconventional reservoirs. Since a robust petrophysical model is critical for accurate reservoir characterization, a key objective of the current study was to obtain reliable well logging data that could support reservoir modeling and early wellsite decisions. Consequently, the logging program included conventional open hole logs, nuclear magnetic resonance (NMR), and elemental spectroscopy. The scope of the work is to assimilate data from the log sand generate a single integrated petrophysical model of the reservoir. The organic shale petrophysics (OSP) was applied to provide petrophysical evaluation based on triple-combo data that has been integrated with advanced logs and core data analysis. The porosity partioning was obtained from NMR data. A detailed mineralogy and organic content were obtained from the geochemical spectroscopy logging. The most relevant results of the petrophysical analysis in this work was to improve fluid saturation analysis using OSP. Kerogen identified with the OSP analysis and the NMR under call porosity were in good agreement. The occurrence of kerogen was supported by the presence of redox sensitive elements, such as uranium, nickel, and molybdenum from core XRF data anlysis. Borehole Image used to identify and characterize types and density of fractures, which contribute to enhance porosity and permeability of these tight reservoirs. A geochemical tool has been designed and developed for the precise determination of formation mineralogy, and lithology, as well as the identification of total organic carbon (TOC). This work proves that the OSP analysis integrated with Core analysis, NMR data is a key in the petrophysical evaluation of unconventional reservoirs including the water saturation. These results, along with geochemical elemental spectroscopy and Electrical Borehole Image analysis, can be used to obtain a more precise petrophysical evaluation.
