... was to identify possible fluid contacts and acquire PVT quality sample data while drilling Paleozoic formations. This is accomplished by extracting and analysing formation gas from the drilling fluid employing the Advanced Formation Gas Extraction System for formation evaluation with a high-resolution...

... of oils with different gravities, including bitumen. The existence of bitumen makes it difficult to determine permeable and recoverable hydrocarbon intervals. The rock characteristics of Buah formation impose significant challenges to traditional formation evaluation methods. Because of the low porosity...

... measurements for improved formation evaluation in both carbonate and sandstone environments are provided in the paper. log analysis dielectric technology Upstream Oil & Gas frequency Sandstone Reservoir bimodal model water saturation dielectric measurement evaluation saturation porosity...

.... And, the formation evaluation results based on wireline versus LWD measurements are discussed. The findings of this study will help reduce the uncertainty associated with the validity of sourceless LWD in replacing wireline in exploration wells. This has many implications for operational efficiency, duration...

... Abstract The formation evaluation of Saudi Arabian tight gas reservoirs presents multiple challenges. The targeted gas resources discussed in this paper include both conventional and unconventional reservoirs. The complexities encountered include varying mineralogy, facies and mechanical...

... Abstract The formation evaluation of Saudi Arabian reservoirs presents multiple challenges. The complexities encountered include varying mineralogy and mixed lithologies, a wide range of porosities and pore types, hydrocarbon viscosity, and variable formation water salinities. Two-dimensional...

... Information Logs (PILs) for well evaluation, facilitates improved monitoring and thus optimization of drilling operations, as well as supports formation evaluation. In the following paragraphs we describe an innovative Spectral Gamma Ray (GR) instrument developed with a NaI(Tl) scintillation crystal, geared...

... testing stages of a total system like this, where we are now, rather than immediately striving for a complete and perfect formation evaluation, the first focus is of course on testing and adjusting the various separate elements, confirming that laboratory performance is repeated in the field...

... Abstract In anticipation of important technological advancements, during the 21 st century, it is worthwhile discussing the frontiers of the current formation evaluation and petrophysics. Today, formation evaluation has limits, dictated by the available logging technologies, core-analysis...

... to provide rock mechanical properties also from drill cuttings. As the techniques to determine several of the key parameters are becoming more firmly established, AML is entering the stage of actually providing a significant input for a complete formation evaluation. aml determination upstream oil...
