At the Sidi Bouzid area located in Central Tunisia, Cenomanian-Turonian reservoir rocks are well outcropping, especially in the Jebel el Kébar and Meloussi areas. The present work confirms that these carbonate intervals constitute the lateral equivalent of the Early-Middle Turonian Biréno and Late Turonian-Coniacian Douleb reservoir Members which are included within the pelagic marls of the Tur...

Net pay thickness is defined as that portion of a reservoir which contains economically producible hydrocarbons with today’s technology, prices, and costs. This thickness is a key parameter of the volumetric calculation of in-place hydrocarbons, well test interpretation, and reservoir characterization. A reservoir interval is considered as net pay when it contains hydrocarbons that can flow at ...

The Las Tres Vírgenes (LTV) geothermal reservoir is a liquid-dominated resource located in the Baja California Peninsula (NW-Mexico) with a currently installed power capacity of 10 MWe. The sustainability of future electricity production at the LTV geothermal field raises concerns about the origin and hydraulic dynamics of exploited geothermal fluids. As part of the present study, water samples...

The article presents the results of lithological and petrophysical investigations reservoir rocks Eocene-Paleocene Formations, which is one main hydrocarbon prolific horizons in Central Eastern Ciscaucasia. These include characteristics pore space parameters for these stratigraphic intervals.

Kepsut-Dursunbey volcanic field (KDVF) is located in NW Turkey and contains various products of the post-collisional Neogene magmatic activity. Two distinct volcanic suites have been recognized; the Kepsut volcanic suite (KVS) and the Dursunbey volcanic suite (DVS). The KVS includes basaltic trachyandesitebasaltic andesite-andesite lavas and associated pyroclastic rocks. The DVS consists of dac...

To figure out gas enrichment laws in Permian volcanic rocks, Sichuan Basin, an association among reservoir-forming elements was explored to analyze forming modes and point exploration prospects accordance with reservoir characteristics, source conditions, fault elongation Zhougongshan Jianyang areas. Results show that there mostly exist porous volcaniclastic rock lava reservoirs of explosive fa...

With the characteristics of low fracturing pressure, little damage to reservoirs, and assuming role carbon storage, supercritical dioxide (SC-CO2) is suitable for development unconventional oil gas resources. Based on tensile failure mechanism rocks, this paper establishes a thermal-fluid-solid coupling initiation pressure model SC-CO2 fracturing. Using model, changes in formation temperature p...

The routine measurement of direction-dependent reservoir rock properties like permeability often takes place along the axial direction of core samples. As permeability is a tensor property of porous materials, it should be fully described by a tensor matrix or by three main permeabilities in principal directions. Due to compaction, cementation, and other lithification processes, which take plac...

The work is devoted to the determination of reservoir properties carbonate rocks, using new modern GIW methods (geophysical investigations wells). main approaches that determine physical and mechanical (PHMP) acoustic anisotropy rocks associated with cavernosity fracturing, as well permeability characteristics field productivity, formations, liquids gases saturating productive horizons are spec...
