Precise Simulation of Acid Stimulation
FPAI accurately simulates acid injection and wormhole propagation in carbonate reservoirs, enhancing the efficiency of acid stimulation treatments.
The most common form of this treatment is matrix acidizing. An emerging technology involves the use of needles in a multilateral fishbone completion (known as fishbones), which are installed by injecting acid at high velocity.
Depending on variables such as rock characteristics, operational conditions, and thermodynamic conditions. Consequently, a sophisticated modeling approach is required to accurately predict and optimize the operation of fishbone treatments.
Acid transport, and wormhole propagation. Wormhole propagation is based on Pore-volume to breakthrough tests (PVbt), typically performed at laboratory to characterize the rock-fluid behavior in acidizing operations.
Simulator FPAI is the result of a FINEP-RCN Norway public call. Simworx, Fishbone AS and Norce Institute developed the R&D project. Project results were published in SPE-218440-MS. Experimental tests were performed to support the numerical developments. Comparative results from lab measurements and modeling shown good agreement. The model was then applied to simulate typical field operations.
