... but increased during lowstand sequences of Upper Shuaiba which is also known as Shuaiba Sequence 5 ( Strohmenger et al., 2010 ). The Upper Shuaiba is distinguished from Lower Shuaiba by the presence of clay, high frequency and low amplitude progradational sequences. This study is going to describe the nature...

Paper Number: SPE-211788-MS
.... The modeled HFTO frequencies and amplitudes agree very well with field measurements. Modeling and field tests show that the implementation of mechanical isolation concepts can protect portions of the BHA from harmful HFTO vibrations. The introduction of mechanical damping elements can reduce the occurrence...

... the injected fluid in the reservoir. A 4D feasibility study predicted saturation changes >50% after 6 years of water and CO2 injection resulting in >10% change in reflection amplitude. Time-lapse Pulsed Neutron logs showed saturation changes of about 25% for both water and CO2 after 3 years of injection...
