... rig cost by increasing the Rate of Penetration (ROP) for LWD Magnetic Resonance from 20m/hr to 40m/hr. This increased ROP caused an overestimation of the total porosity from magnetic resonance. A newly introduced correction technique enables the compensation of effects due to high ROP on magnetic...

... desert environments of Saudi Arabia with a complex near surface. We present two methods for prestack seismic signal enhancement based on utilization of neighboring traces. The first method, called supergrouping, performs local summation of traces using a global normal moveout correction to align...

... to avoid correcting for properties difference between the testing fluid and reservoir fluid. This study focused on the latter approach to quantify the correction to gas adsorption. The Cui et. al, model based on Langmuir adsorption isotherm is modified to Cui-Freundlich isotherm which has been proven...

..., whether we use coarse grid-blocks or fine grid-blocks in simulation. The approach is based on the correction of laboratory relative permeability data, using the shock front water saturation (S wbt ) obtained from fractional flow curve. S wbt is the water saturation at the contact point between a tangent...

... Abstract The conventional approach to gas extraction at the surface is often flawed because of static extraction efficiencies used during drilling operations; a dynamic approach has proven to be much more effective. A dynamic extraction efficiency correction captures inter- and intra-molecular...

.... Wireline tools use a mechanical caliper to measure hole size, and to quantify the amount of environmental correction required. While in LWD tools, ultrasonic time-of-flight method is used to measure the tool's standoff. These differences in design and sensor physics will make ultrasonic calipers to have...
