...Equations governing CO2 adsorption in shale Gas adsorption occurs when gas molecules forms adsorbate film and sticks on the adsorbent surface ( Keller & Staudt, 2005 ). The mechanism of CO2 storage in shale is primarily via physisorption (physical adsorption). Physisorption takes place...

... Abstract Advancements in the technique for early estimation of the hydraulic fracturing potential of fracturing fluid in different shale formations are needed to successfully stimulate reservoir volume and recover the trap hydrocarbons. The determination of fracture initiation and propagation...

... located in Offshore Northwest Java, Indonesia. Field structure is composed of multiple reservoir sandstones with interlayer shales. Two sandstone units with gross thicknesses up to 60 feet, effective porosity of 15% and permeability of 8 mD were targeted for hydraulic fracturing. An integrated approach...

... Abstract Peninsular Malaysia is made up of three fundamental stratigraphic belts; the Central Belt, the Eastern Belt, and the Western Belt with little data on their shale lithologies. The Belata Formation is situated in the Western Belt and is at the southernmost part of Tanjung Malim...

... of porosity, water saturation, and permeability. A saturation height function was built from special core analysis (SCAL) to provide an independent saturation estimate for calibrating the petrophysical model. The Thomas-Stieber method, a well-known method for detecting and quantifying laminated sand-shale...

... Shtrikman Upper Bound is useful to model the compressional and shear velocities of grain-supported clean sandstones as function of porosity, whereas matrix-supported claystone compressional velocities follow the concaveHashin Shtrikman Lower Bound. The corresponding shear velocity shale data plot similarly...

.... The predicted reservoir pore pressure gradient was 2.27g/cm 3 and actual measurement was 2.28 g/cm 3 ; 2) The top depth of over-pressured reservoir, S1 Sand, was predicted within 3 meters versus actual depth. The 9-5/8" casing successfully set in shale formation above S1 Sand, which enabled a manageable...

... Abstract Successful fracturing processes in shale, during shale gas drilling and production, is an effective way to reduce environmentally and cost risks. Fracability of rocks is highly affected by the rock’s quartz, carbonate and/or clay content. Thus, a fair understanding of shale quartz...

... resolution of a common oil-based resistivity tool often fails to capture structurally complex, thinly laminated sand-shale formations. The low resistivity response results from high resistivity sand layers suppressed by low resistivity shale layers, which can result in misinterpretations of calculating high...

... Abstract Shale stability and differential sticking are the main challenges while drilling through shale and sand sequences. Conventional mud systems cannot always provide the required wellbore stability and sustained high overbalance, which has led to an increase in use of ‘customized fluids...

... Abstract When building a 1D geomechanical model for the Rang Dong field in Cuulong basin, offshore Vietnam, the rock structure was found to be very complex. In addition to inter-bedded shale and sand sequences in the overburden, there is an overpressured stratum immediately below and above...

... of these attributes show that the lithology and pore fluid effect are separated orthogonally to each other. The lithology differences are distinguished in the SQp attribute, while the fluid types are distinguished in SQs attribute. The gas sand is separable from shale background and wet sand easily. Furthermore...

Our study of LR reservoirs, commonly misinterpreted as wet/non-productive zones, comprises inter- vals of alternating sandstone and mudstone beds (laminated sand/shale). The sandstones include dispersed and structural clays, conductive minerals...

... Abstract Clastic-reservoir characterisation of the Malay basin poses numerous challenges resulting from the silty and clayey nature of its reservoirs. To date, different practitioners use shale volume (Vsh) and clay volume (Vcl) in an exchangeable fashion, where the former is rock...
