A Fast History Matching and Optimization Tool and its Application to a Full Field with More than 1,000 Wells

Autor: Guotong Ren, Zhenzhen Wang, Yuanbo Lin, Tsubasa Onishi, Xiaoyue Guan, Xian-Huan Wen

Publikováno v: Day 1 Tue, March 28, 2023.

In this work, we study a waterflood field containing over 1,000 wells and the modern field management techniques with full-fidelity 3D geo-cellular reservoir models become computationally prohibitive. To overcome the difficulty, we developed a novel

Reservoir Connectivity Identification and Robust Production Forecasting Using Physics Informed Machine Learning

Autor: Masahiro Nagao, Akhil Datta-Gupta, Tsubasa Onishi, Sathish Sankaran

Publikováno v: Day 1 Tue, March 28, 2023.

Routine well-wise injection/production data contain significant information which can be used for closed-loop reservoir management and rapid field decisions. Traditional physics-based numerical reservoir simulation can be computationally prohibitive

Streamline Tracing and Applications in Dual-Porosity Dual-Permeability Models

Autor: Tsubasa Onishi, Shusei Tanaka, Hongquan Chen, Dongjae Kam, Jiang Xie, Zhiming Wang, Xian-huan Wen, Akhil Datta-Gupta

Publikováno v: SPE Journal. 27:1943-1961

Summary Streamline-based methods have proven to be effective for various subsurface flow and transport modeling problems. However, the applications are limited in dual-porosity and dual-permeability (DPDK) system due to the difficulty in describing i

Computing Pressure Front Propagation Using the Diffusive-Time-of-Flight in Structured and Unstructured Grid Systems via the Fast-Marching Method

Autor: Hongquan Chen, Tsubasa Onishi, Akhil Datta-Gupta, Jaeyoung Park

Publikováno v: SPE Journal. 26:1366-1386

SummaryDiffusive-time-of-flight (DTOF), representing the travel time of pressure front propagation, has found many applications in unconventional reservoir performance analysis. The computation of DTOF typically involves upwind finite difference of t
