CO2 pre-fracturing belongs to economically and environmentally valuable CCUS projects, but there is currently a lack of continuous and effective means to monitor the CO2 extraction rate post-fracturing. Current practices both domestically and internationally mainly rely on intermittent monitoring through handheld CO2 detectors or sampling bags for chemical analysis, which does not adequately meet actual operational needs. CO2 online monitoring technology monitors CO2 production to calculate CO2 storage rates.

In the post-fracturing flowback stage of horizontal wells, which is a crucial link between completion and production, the rationality of the flowback system significantly impacts fracturing effectiveness assessment and subsequent production efficiency. The intelligent control and monitoring technology for gas-liquid-sand in horizontal wells can manage pressure drops during flowback, control sand in the formation, optimize flowback systems, monitor Gas-Oil Ratio (GOR), and assess fracturing effectiveness during the flowback process.

Open hole logging technology is an important method for underground oil and gas exploration. It involves using instruments that reflect various physical properties such as heat, sound, electricity, light, magnetism, and nuclear radioactivity to measure the different physical characteristics of formations in a drilling well. By processing and interpreting this data based on their respective physical principles and interrelationships, it helps identify the porosity, permeability, fluid properties, and distribution of underground rocks. This information is crucial for discovering oil and gas reservoirs, assessing reserves, and predicting production rates. Our company specializes in conventional logging services for vertical, directional, and horizontal wells, as well as special logging services (dielectric scanning logging, elemental capture logging, nuclear magnetic logging, cross-dipole acoustic logging, micro-resistivity imaging logging, pressure-controlled closed chamber coring), and wellbore quality logging operations and data processing and interpretation.

Tracer production liquid profile testing technology is one of the important technical means for evaluating the effectiveness of new well fracturing and assessing the liquid production capacity of production wells. Conventional tracer testing for liquid production profiles has issues such as short effective lifespan, poor thermal stability, low recovery rates, significant formation adsorption losses, and low accuracy.
