“…The static reservoir model was prepared using Schlumberger's Petrel software suite, 2015 version, on the basis of the latest processed seismic data from the J1 field. Geological modeling is highly important because it (1) provides a robust means of field evaluation and (2) enables volumetric calculations that provide the best technical case for determining static stock tank oil originally in place (STOOIP) and gas initially in place (GIIP) values [42]. The inputs for reservoir simulation were supported by history-matching the test well to the potential drilling targets and their associated profiles.…”

Recovery efficiency is a key factor in decision-making in oil and gas projects. Although structural setup and well type considerably influence waterflood recovery, few studies have explored the performance of highly deviated wells during the waterflooding of complex shallow reservoirs. Here, we applied numerical simulations to investigate the performance of vertical, horizontal, multilateral, and highly deviated wells during waterflooding of complex shallow reservoirs using the J1 Oilfield as a case study. Recovery efficiencies of 31%, 33%, 31%, and 26% could be achieved for vertical, horizontal, multilateral, and highly deviated wells, respectively. The gas production rate was 39% higher in the vertical wells than in the other types. Highly deviated wells yielded the highest water-cut (80%) over a short period. Highly deviated wells delivered the least production, and, despite branching laterals, multilateral wells were also not the most productive. Our results provide insights into the performance of different well types during the waterflooding of green heterogeneous non-communicating reservoirs and present an example of the successful practical application of waterflooding as an initial recovery mechanism when oil is near the bubble point. This study indicated that multilateral wells are not a panacea in reservoir development. Highly deviated wells are the ideal choice for the shallow, heterogeneous non-communicating reservoirs when economic and environmental impact are considered in decision-making. Well design should be a case-by-case study considering reservoir characteristics, economics, and environment impact.

“…The estimation of the volume of hydrocarbon in a reservoir is a core task in the upstream petroleum industry, and it provides the basis for a field development plan [1][2][3]. Two types of methods are used for evaluating the volume of hydrocarbon in place (HIP): volumetric methods and dynamic methods [4,5].…”

“…Dynamic methods are based on principles that depend on production data. They include the Material Balance Equation and simulations, while volumetric methods are static and rely on the volume of the net reservoir and petro physical properties, including the DOI: 10.31695/IJASRE.2023.9.12.5 area (A), the thickness (h), the net pay (he), gross thickness (ht), the porosity (Φ), the water saturation (Sw) and eventually the formation volume factor of hydrocarbon (FVF) in place [2,6] .…”

Cephy is a software toolkit written inJava that enables the user to perform spatial interpolation of subsurface data by ordinary kriging. Key features of the software include data exploration by map plot with symbol dimension proportional to the magnitude of the property at a given location;variogram modeling and interpolation of petrophysical properties;as well as oil in placeestimationper area unit throughout the reservoir. Cephy enables the user to define the tolerance and the minimum number of pairs required to validate the experimental variogram of the corresponding lag distance when learning the relationship between geolocated data. The software is entirelymade of a graphical user interface for adjusting the variogram modeling parameters and visualizing the subsequent interpolationally-generated map.Cephy is applied on Kinkasi reservoir in Kinkasi field (Coastal basin of DR Congo) to demonstrate its functionalities. The result supports a better understanding of oil distribution throughout the reservoir and can be used as a baseline forthesuggestion of new infill drilling locations.
