... to understand key reservoir properties, quantitative contribution to production and total drainage height. Key observations include: 1) By comparing various co-development and infill development strategies in neighboring areas, we determined co-development reduces depletion effects and well interaction while...

... production which impacted the economics of the field. An innovative solution of borehole acoustic reflection imaging combined with production logging was proposed in a horizontal well which suffered from high water cut. The objective was to determine which stages contributed to most of the water production...

... for candidate selection and post-production drivers that contribute to their success. In this study, we propose a methodology that involves developing models trained on historical fractured and refractured wells to evaluate the impact of different parameters on the post-refrac performance of each well...

... not depend on mechanistic fractures or simulation model assumptions. The method also enables the identification of dominant flow regimes by using terms with the highest contributions instead of the usual line fitting procedure. Traditional methods like RTA tend to be interpretive and not suitable for field...

... Abstract The underperforming production wells in many pilot research are commonly ascribed to two key contributing components: geological variation and completion strategy. Traditional statistical analysis and machine learning approaches have overlooked the integration of frac-hit and its...

... enabled measurement of inter-bench and intra-bench production interference between wells. Time-lapse geochemistry analysis helped evaluate contribution from each bench for a given well. Completion and spacing sensitivities were run to optimize development planning decisions. Extensive overlap was seen...

... Abstract Drainage behaviors (drainage frac height or DFH, zonal contribution, and drainage variation through time) are crucial information to evaluate well performance. In this study, we analyzed drainage data derived from geochemistry-based model correlating produced oils back...

... reservoir contributions to producing unconventional wells. Failure to account for geologic variability, analytical limits, and source and reservoir signatures can lead to misleading and costly allocations. Further, lack of recognition of what causes chemical variation beyond simply source facies leads...

The correlation between initial production CGR (CGRi) and the average compound depth of the horizontal extent of these wells along the navigation zone was also investigated to contribute to the staggered wells' analysis. The condensate yield has been observed to change above the phase envelope depending...

Multivariate analysis techniques are then applied to the geochemical drainage and log data from these key contributing zones, allowing for identification...

Data from Wilson show most oil originates in the drilled interval, and that contribution increases over time. Oil...
