... were to quantify fluid saturation variation in the Bakken petroleum system and relate it to rock facies in support of reservoir simulation, oil-in-place estimates, and acreage optimization. Additionally, we compared hydrocarbon extraction techniques to better understand fluid loss from the time core...

... model can be applied to a multi-well, log-curve data set, individual facies summed within a given unit, and mapped. We demonstrate this methodology using the Middle Leonard (LNRDM; Lower Permian; also known as the Lower Spraberry Shale), an unconventional target in the Midland Basin (MB) as an example...

..., and provide decision support through predictive modeling scenarios. A 3D facies model, based on object-oriented geostatistical modeling was constructed using a combination of vertical lithology proportion curves (from vertical wells) and reservoir net-to-gross (NTG) maps across the entire stratigraphic column...

... belt, and a third asset where mudstones facies are intruded by magmatic sills. This manuscript contributes with a complete evaluation process from exploration to pilot stages and when conditions are appropriate to a development phase of unconventional reservoir from a multidisciplinary team standpoint...

... Abstract The Bone Spring Formation in the Delaware Basin has more than 23,000 economic drilling locations remaining in the basin. How do you identify and high-grade those remaining drilling opportunities? While spacing and completion still matter, the best wells will be in the right facies...

.... Density, P-wave and S-wave impedance are estimated, from which Young’s Modulus and Brittleness Index are calculated. The second CNN simultaneously estimates the effective porosity, clay, kerogen, and quartz volumes. A Bayesian lithofacies method was used to perform facies classification and generate...

... strategy choices. The outcome of the proposed learning model is an automated engineered completion design adapted to various facies along the lateral, resulting in prediction of stage-production performance. A new type of log acquisition that mixes well testing and logging techniques has been developed...

... and thickness of dissolution zones. High-resolution electrical image logs of more than 60 wells were used to set up the dominant dissolution facies window, 7 facies were summarized based on electrical image logs with calibration of core data, including cave, alveolate vug, stratiform vug, fracture-vug, isolated...

... Leonardian section. The model includes results from facies and stratigraphic analyses, structural interpretation, well coverage, petrophysical interpretations, geo-mechanical interpretations, and hydrocarbon properties. Bone Spring and Wolfcamp formations were subdivided by major zones and mapped...

... process to determine log-scale Petrophysical Rock Types (PRT) (Akpulat, 2019). Log-based PRTs provide high resolution vertical facies definition that serves as the basis for Occidental's latest generation unconventional petrophysical modeling workflow. An extensive inventory of high-quality 3D seismic...

... geomodel was built (facies and petrophysical properties) and flow modeling conducted to capture the reservoir heterogeneity and then evaluate the fluid flow in the upper shale member of Zubair formation, Luhais oil field, southern Iraq. The most challenging part of the reservoir modeling process...

... act as source rocks and represent periods of anoxia and organic preservation. The calcareous, carbonate-rich chalks act as reservoirs and represent periods of carbonate production with varying oxygen paleo water conditions. Elemental geochemistry is very useful in characterizing various mudrock facies...

... mudstone (F6). Out of these six facies, 95% of the UBS succession consisted of the three facies F1, F2, and F4. Facies F1 was the most dominant facies in the UBS, followed by facies F2. The presence of facies F4 in the UBS is localized. The remaining three facies make up less than 5% of the entire UBS...

The fan systems display radially distributive, predictable sedimentation patterns with fan axes containing carbonate dominated accumulations while fan fringe...

... investigations at multiple scales and in different applications. While lithological and petrophysical facies have been used in reservoir characterization to associate with storage capacity and flow characteristics of rocks, mechanical stratigraphy and its role is less known and more complex to identify...

... can be estimated with an understanding of STOOIP, shale facies variations and source rock maturity. The implications on producible volumes retained in the shales has a large impact on any work focused on recovery factors, well estimated ultimate recovery (EUR), or considerations of EOR programs...

... are the equivalent to the one estimated from petrophysical analysis on logs as opposed to the static properties evaluated from core data. All geomechanical properties were analysed in close relation with three main facies characteristic for the Duvernay Formation of our study area: facies F1, carbonate or limestone...

... using bandlimited log data was able to separate organic rich high TOC facies from siltstones and carbonates. To conclude, an integrated approach involving geology, petrophysics, rock physics and inversion feasibility study increased our understanding of the basin and set path for further analysis...
