Optimal hydrocarbon recovery depends strongly on predicting the reservoir quality and drive mechanism, this could be achieved by petrophysical analysis. This research evaluated properties of sands in an Oil producing Field, onshore Niger delta, Nigeria using techniques. Results from Petrophysical evaluation, showed that average porosity values reservoirs ranged between 0.15 0.24 while water sat...

Rock strength is an essential and effective property in the rock drilling, excavation, cost evaluation. This work aims to examine a practical approach evaluate geomechanical properties that control drillability, such as uniaxial compressive (UCS) by utilising some petrophysical parameters (porosity bulk density) elastic (Young’s modulus, slowness). To achieve this aim, study was conducted on Ju...

We consider a variant of the game of Cops and Robbers, called Lazy Cops and Robbers, where at most one cop can move in any round. We investigate the analogue of the cop number for this game, which we call the lazy cop number. Lazy Cops and Robbers was recently introduced by Offner and Ojakian, who provided asymptotic upper and lower bounds on the lazy cop number of the hypercube. By coupling th...
