The College of Engineering witnessed the public discussion of the Master’s thesis by student Shamm Tariq Abdul-Kadhim in the Petroleum Engineering department. The research is titled: Prediction of Multilayer Tank Performance using Multi-layer Transient Analysis and Production Logging.
The thesis aimed to study traditional pressure data analysis methods, conducted through the use of downhole pressure gauges placed at a fixed depth inside the wellbore. These gauges serve as a primary source for calculating permeability and damage as average values for the reservoir, even when the reservoir consists of multiple layers, Multiple-layer well testing techniques were employed, allowing for the individual calculation of each layer’s characteristics.
The study yielded several key findings, notably the efficient use of Selective Flow Performance (SFP) technology in wells producing from multiple layers to determine their pressures. However, it was observed that this technique is not suitable when multiple fluids are present or when the layer is non-producing. In such cases, reliance on the calculated pressure during the production testing process using the Straddle Isolation Packer (SIP) technology is a viable alternative, especially for wells that cannot be shut in.
