Capacitance Resistance Clustered Model for Mature Peripheral Waterflood Performance Prediction & Optimization

Optimizing water injection rate distribution in waterflooding operations is a vital reservoir management aspect since water injection capacities may be constrained due to geographic location and facility limitations. Traditionally, numerical grid-based reservoir simulation is used for waterflood performance evaluation and prediction. However, the reservoir simulation approach can be time-consuming and expensive with the vast amount of wells data in mature fields. Capacitance Resistance Model (CRM) has been widely used recently as a data-driven physics-based model for rapid evaluation in waterflood projects. Even though CRM has a smaller computation load than numerical reservoir simulation, large mature fields containing hundreds of wells still pose a challenge for model calibration and optimization. In this study, we propose an alternative solution to improve CRM application in large-scale waterfloods that is particularly suitable for peripheral injection configuration. Our approach attempts to reduce CRM problem size by employing a clustering algorithm to automatically group producer wells with an irregular peripheral pattern. The selection of well groups considers well position and high throughput well (key well). We validate our solution through an application in a mature peripheral waterflood field case in South Sumatra. Based on the case study, we obtained up to 18.2 times increase in computation speed due to parameter reduction, with excellent history match accuracy

Pelatihan Dan Pendampingan Legalitas Usaha Untuk UMKM Desa Cupak, Kecamatan Ngusikan, Kabupaten Jombang

Business legality is a standard that must be met by economic entities. Micro, small and medium enterprises (MSMEs) must meet these requirements to compete in the free market era. This requirement is problematic because many business actors do not have business legality. We face various obstacles such as lack of means to ensure legality, difficulty in responding, and lack of knowledge. This paper discusses the results of community service provided, namely assistance and the importance of business legality for MSMEs. The purpose of this service is to raise awareness and provide a framework of thinking about the importance of business legality for MSMEs to compete in the open market. The implementation method used is touse in-depth interviews, observation, and documentation. The result of the implementation is the issuance of a Business Identification Number (NIB) which is the legal umbrella of an official business and recognized by the state through the OSS Institution or known as Online Single Submission
