Paper Number: SPE-195188-MS
... is presented to perform reservoir characterization from wireline nuclear magnetic resonance (NMR) data, in the absence of any core, in offshore gas-bearing wells. This includes computing T 2 cutoff, hydrocarbon saturation, permeability, and poro-fluid sand facies determination. NMR is a shallow...

... in all of the fracture patterns. The results demonstrate that the ROC model proposed in this work can be used to study the flowback process affected by properties such as wettability, permeability, initial water saturation, and reservoir pressure. Consequently, it has potential for guiding water...

..., but an optimal value for a specific field depends on the anticipated oil saturation and the transportation length between injection/production well pairs. A compound's octanol/water partitioning coefficient (K OW ), provides a good indication for the candidate compound selection, but should be...

T 2 time distribution and one-dimensional saturation profile measurements were obtained using a 2-MHz nuclear magnetic resonance instrument before and after centrifuge experiments. Moreover, pore size distribution was determined from Mercury Intrusion Capillary Pressure (MICP) and...

Calculated results matched the experimental data, including recovery of each component and gas saturation profiles inside the core. The simulation revealed the presence of countercurrent flow inside the...

These products displaced trapped oil by altering saturations, rock wettability or improving waterflood sweep efficiency resulting in enhanced oil recovery from oil reservoirs. And because the microbes needed plentiful but cheap nutrients to grow and produce these products, MEOR...
