Interpretation of temperature profiles during soak periods in steam-stimulated wells

Abstract

To address the problems existing in testing steam injection profiles in a steam-stimulated well during steam injection and production periods, this paper proposes that the temperature profile in the completion interval could be tested during the soak period. A mathematical model for calculating the vertical distribution of temperature in a single layer reservoir is established based on the temperature characteristics of steam stimulated reservoirs, and the vertical distribution of temperature in a single layer reservoir could be obtained and heat loss could be calculated. The temperature, which is disturbed by thermal conduction in a multilayer reservoir, and heat loss could be derived based on the superposition principle of temperature potential. This paper establishes a multilayer testing temperature profile interpretation method and interprets the actual test temperature profile of Well Gao 3-7-66. The results indicate that the temperature profile in the soak period can reflect the thermal absorption conditions in various reservoir beds.

Potential Use of Polysaccharides Natural Polymer in Plants as an Alternative to Chemical Enhanced Oil Recovery (EOR) to Increase Oil Production in Indonesia

“…Even (Rostami, Kalantari-Meybodi, Karimi, Tatar, & Mohammadi, 2018) shows that this method has been used since the early 1960s and is widely used because its application is relatively simple and effective for controlling fluid mobility (Quadri et al, 2015). Research result (Huiqing, Hongling, & Peixi, 2007;L. Wang, Xu, Guo, Peng, & Tang, 2011) in Chinese oil fields, indicating that the appropriate polymer concentration to increase oil production should be higher than 1,500 ppm.…”
