Pressure Transient Analysis

Pressure Transient Analysis (PTA) is a technique used in the oil and gas industry to evaluate the condition and characteristics of a well and its reservoir. By analyzing how pressure changes over time in the well when production or injection is interrupted or altered, engineers can determine properties such as reservoir size, permeability, and the presence of barriers. This helps optimize well performance, plan future development, and identify issues like leaks or drainage problems. Essentially, PTA provides insights into the subsurface environment by interpreting pressure responses, enabling better decision-making for efficient resource extraction.
