... Abstract Carbonate rocks are very heterogeneous and have very complex pores structure due to the presence of intra-particle and inter-particle porosities. This makes the characterization and evaluation of the petrophysical data, and the interpretation of the carbonate rocks a big challenge...

... and subjective. To an extent, optical point counting is routinely used quantitatively to estimate porosity, cement, and granular features. Overall, thin section descriptions require specialist human skill and an extensive effort, as it is repetitive and time consuming. Thus, a manual process limits the overall...

... mud losses have not been observed in any horizontal wells so far in the development of Oilfield A. For these reasons Reservoir 2 is considered to be a Type 4 reservoir i.e. hydrocarbon storage and productivity are controlled by matrix porosity and permeability ( Nelson, 2001 ). It is not considered...

.... NMR and Spectroscopy were used to refine lithology and porosity, which reduces the associated uncertinity in the evaluation of total organic carbon (TOC) and volumes. The advanced elemental spectroscopy data provided the mineralogy, the amount of carbon in the rock, and consequently the associated...

To establish correlations, thickness maps were compared to maps of log porosity, facies, diagenetic features, geophysical attributes, cumulative oil production and water cut...

... / shale can be confirmed from intervals with lower T 2 component presence and increased GR reading. Not all low GR intervals were zones of interest. Coupled with NMR data, one could easily conclude that intervals with low GR and high resistivity were tight low porosity limestone zones and should...

... The main reservoir quality influencer is the diagenetic overprint reflected in cementation and dissolution phases, and directly influencing the porosity variation. Being a tight reservoir with average permeability of 1 mD and ranging between 0.01 mD and 6 mD has resulted in the inferred static...
