Abstract Dedicated exploration efforts targeted on the Jurassic reservoirs in North Kuwait culminated discovery of six separate fields, encompassing an area approximately 1,772 km2. These are known to hold commercial accumulation gas, gas condensate and volatile oil currently early phase development. The producing belong Marrat, Sargelu Najmah Formations Toarcian Tithonian ages. consist tight carbonates with several other complex lithologies naturally fractured fractures acting as a driver...
Abstract Evaluating natural fractures in tight carbonate reservoirs during the exploration and early development stages is critical order to reduce geological uncertainty determine well trajectory future horizontal drilling. Challenges are often found both acquiring adequate data assessment of fractures/sub-seismic faults oil based mud borehole environment. This paper summarizes part experience learned from use an optimal dataset addition a workflow on fracture characterization for deep...
Abstract A number of structures are producing hydrocarbons in commercial quantity from the carbonate reservoirs Middle Marrat Formation Northern part State Kuwait. Seismic resolution these deep Toarcian age is strongly affected by multiples overlying Gotnia-Hith salt-anhydrite layers impacting true understanding internal depositional architecture seismic data making it difficult to make realistic geological models. An extensive coring campaign adopted over a period time for improving...
Lithocodium mounds are early Cretaceous sedimentary structures described in the literature from outcrops, however, never subsurface. The objective of this work is to identify and characterize subsurface along a 25,000 ft horizontal well. Drill cuttings sampled at 100 interval observed thin sections define quantify key indicators (bioclasts, facies, texture). Logging-while-drilling (LWD) gamma ray (GR), density, neutron, resistivity logs acquired with LWD high-resolution borehole image (BHI)...
Abstract Electrofacies based on conventional logs are found as strongly correlated to core lithofacies, thin section microfacies, and petrophysical measurements (f/k MICP) long the carbonate pore system remains simple. Once dual porosity is present, it that neural network using can not distinguish 2 rock types having same range of but different porosity-permeability relation. The illustrated by strong leaching (i.e. dissolution) overprinting primary interparticle a grainstone, responsible...
Application of the neural-network technique using electro-logs for rock-typing carbonates is challenging because initial depositional fabric often overprinted with diagenesis and tectonics. This presentation shows first successful application Marrat carbonate reservoirs in two producing oil fields Kuwait. Conventional electrologs from ten key wells were used rock-typing, whereas unconventional nuclear magnetic resonance (NMR) borehole image logs four these integrated to understand quantify...
Summary We present how a comprehensive geological study helped in the understanding distribution of heterogeneity example nodular facies. The result an in-house workflow based on core CT-scan information provided quantification heterogeneities. These results are used to show that oil can still flow, even when logs indicate high water saturation values. anticipated by method were confirmed well tests.
Summary The field, offshore Qatar, is located within the Qatar Arch, part of Central Arabian Plate tectonic province. It consists stacked, thin, mostly carbonates but also clastic reservoirs developed through horizontal wells. Hence, conventional time depth conversion results in surfaces and uncertainty unsuitable for static model building drilling prognosis areas where information from wells available. This paper will illustrate challenges associated with such settings integration well...
