Determination of Reservoir Characteristics Using Geostatistical Analysis
… way to estimate the spatial distribution of reservoir properties. Geostatistical methods, such as kriging, cokriging, and sequential simulation have been applied to integrate well-log data and seismic attributes. However, conventional deterministic methods of geostatistics, kriging and …

Sedimentology, Diagenesis and Reservoir Characteristics of Eocene Carbonates Sirt Basin, Libya
ABSTRACT The reservoir quality of Middle Eocene carbonates in the intracratonic Sirt Basin (at the northern margin of the African continent) is strongly influenced by depositional facies and various diagenetic modifications. This thesis investigates the petrography, sedimentology, diagenetic …

Petrography, Sedimentology, Diagenesis, and Reservoir Characteristics of Some Pennsylvanian Phylloid Algal Limestones: Kansas and Utah, u.s.a. (United States)
The Paola and Raytown limestone members of the Iola Formation (Missourian) of southeastern Kansas have been systematically analyzed with 1200 thin sections. These rocks contain a typical Pennsylvanian biotic assemblage of phylloid algae, bryozoans, encrusting foraminifers, fusulinids, Composita, …

A novel diagnostic fracture injection test workflow considering natural fractures
… injection test (DFIT) are used in unconventional reservoirs to determine reservoir characteristics for future fracture design and production. DFIT consists of creating a minifrac by pumping small amounts of water and monitoring the pressure response. The presence of natural fractures can heavily …

Inclusion of Fracture Skin in Duong’s Model of Rate-Decline Analysis for Fracture-Dominated Shale Reservoirs
… in the US oil and gas industry. Unconventional reservoirs vary significantly in their reservoir characteristics and production methodologies when compared to conventional reservoirs. The differences between conventional and unconventional reservoirs lead to significant duration of transient flow …

A Regional Study Of Wilcox Reservoirs In The Deepwater Northern Gulf Of Mexico
… has considerable economic challenges due to the reservoir characteristics. The purpose of this study is to provide a regional study of the Wilcox reservoir economics and quality. Great white field is the most successful Wilcox field located in the northwestern Gulf of Mexico and Jack and St. Malo …

Origin and Correlates of Viral Rebound in SIV-Infected Rhesus Macaques Following Discontinuation of ART
… remain largely unknown. We investigated detailed reservoir characteristics and viral rebound dynamics in 18 Simian Immunodeficiency Virus-infected rhesus macaques treated with antiretroviral therapy for 70 weeks and then necropsied after a 12-day analytical treatment interruption (ATI). Using …

Parametric and predictive analysis of horizontal well configurations for coalbed methane reservoirs in Appalachian Basin
… and permeability values. Due to highly complex reservoir characteristics, different drilling techniques have been developed in order to improve ultimate gas recovery in the shortest possible time. It has been claimed that horizontal drilling is the optimum completion technique used in this …

Depositional and Diagenetic History of the Permian Unayzah A Reservoir, South Haradh, Saudi Arabia with Implications for Deep Gas Exploration and Development
… gas producer but is characterized by significant reservoir heterogeneity related to complex interbedding, on the scale of 5 meters or less, of eolian dune, sand sheet, interdune and ephemeral (playa) lake facies. Diagenetic products in Unayzah A developed during a continuum of eogenetic and …

Microfacies analysis of the lower paleocene beda formation in Western Concession 59 and Block 59F, Sirte Basin, Libya /
… contributed greatly to porosity development. Reservoir traps of the Beda Formation are characterized by normal fault blocks and the general reservoir characteristics/properties appear to be facies controlled.

Lithostratigraphic investigation of a Late Devonian carbonate-evaporite sequence; the Duperow Formation, Williston Basin, North Dakota
… and establish units with appreciable amounts of reservoir characteristics. The main diagenetic features observed are micrite enveloping and micritization, calcite cementation, dolomitization, compaction, dissolution, and anhydrite cementation. Only dolomitization and dissolution increase porosity …

Depositional Facies Analysis of the Cotton Valley Group Sandstones of the Blackburn Field, Northern Louisiana using Well Logs and Cores; Implications for Carbon Sequestration
… consists of tight sandstones with heterogeneous reservoir properties due to variations in depositional environments and diagenesis, spanning across eastern Texas through the Florida panhandle. It has served as a hydrocarbon target since the 1940s, and with recent technological advances, there is …

Principles of Unitization
… After engineering studies have determined the reservoir characteristics, negotiations begin with royalty owners, many of which, not realizing the benefits of unit operations, refuse to permit consolidation of their interests. The state is a party to the formation of a unit and its conservation …

Problems with a localized nature in exploration seismology
… and become aware of their potential for reservoir characterization. Motivated by this observation I introduce a local solver for simulating elastic reflections in a region of interest. These elastic reflections can then be used for AVA and PVA to for instance invert for reservoir …

Reservoir characterization and geology of the coals and carbonaceous shales of the Cherokee group in the Cherokee Basin, Kansas, Missouri and Oklahoma, U.S.A.
… The decline curves of these unconventional reservoirs in the Cherokee Basin resemble conventional production decline curves rather than the typical dewatering curve for coalbed methane wells. Throughout this study the integration of geology, production, reservoir characteristics and …

Physical and Numerical Modeling of SAGD Under New Well Configurations
… optimizing the well configurations for different reservoir characteristics. The role of well configuration in determining the performance of SAGD operations was investigated with help of numerical and physical models. Since mid 1980’s, SAGD process feasibility has been field tested in many …
