Elastic Impedance Simultaneous Inversion for Multiple Partial Angle Stack Seismic Data with Joint Sparse Constraint

Elastic impedance (EI) inversion for partial angle stack seismic data is a key technology in reservoir prediction within the oil and gas industry. EI provides consistent framework to invert data, just as AI does post-stack data. The commonly used process by angle. Hence, inverted different angles may be nonconforming, especially with low signal-to-noise ratio. This paper proposes simultaneously multiple obtain at once. To conformable EI, we joint sparse constraint on reflection coefficients angles. Then, objective function simultaneous was constructed. Next, synthetic profiles three were show superiority of proposed method compared conventional method. At last, real line test feasibility practice. results showed that it an effective new alternative estimate from
