... Abstract A translation scheme must be established to link core properties, such as rock type and permeability, from core intervals to non-cored intervals. Such a translation determines accurate and consistent permeability predictions across the field. This study focuses on an Early - Middle...

... (HPHT) horizons at depths between 12,000 and 20,000 feet, where the stress and temperature are extremely high in addition to micro-Darcy levels of reservoir permeability. This has made the exploration activity more challenging. To overcome the extreme challenges and to help assure the success...

... of chemical surfactants, acidizing and etc. The proposed graphical procedure as shown in Fig.3 can be used to evaluate reservoir's potential for APT and consequent attempts to minimize and remove associated formation damage. Current Predictive Formulas Permeability Damage Ratio...

... Abstract Developing and producing a deep gas asset is a challenge because the reservoir is often of low permeability, commonly referred to as tight gas. In some cases, the wells are drilled under-balanced to prevent damaging the reservoir. Very often, it is necessary to drill through weak...

... g )   d p In the region 1 both gas and condensate flow and relative permeability can be calculated from material balance (4) k r g k r o ( p ) = ( R p − R s 1 − R v R p ) ( B g d μ g B o μ o...

... reservoirs, it became apparent that microemulsions had several properties that could possibly minimize formation damage. One consequence that arises in transitioning from higher-permeability to lower-permeability formations is that capillary-pressure effects no longer become negligible. Capillary...

... Abstract Our recent work on deep tight gas reservoirs containing red and white sandstones ( Potter et al., 2009 ) has shown that the presence of small amounts of hematite in reservoir samples has a dramatic effect on permeability. Such conclusions were made using laboratory based low and high...

... Abstract Occurrences of deep gas are commonly found in clastic reservoir rocks. The great depths of these reservoir rocks often result in rocks with low porosity and poor permeability. In order for these reservoirs to be productive, natural fracture systems or induced fractures from stimulation...

... the pores, and makes possible fast and accurate computations of essential rock properties. Key reservoir parameters, such as porosity, absolute and relative permeability, can be computed within a few hours up to a couple of weeks. Unlike traditional physical measurements, digital imaging-based...
