Focusing on offshore oil and gas energy exploration, we carry out marine 2D and 3D seismic acquisition using different acquisition equipment such as streamer and OBN, together with complete geophysical technologies, supporting high-precision seabed geological imaging and oil and gas resource evaluation.

Integrating streamers, OBN, airgun arrays, high-precision satellite stations and GNSS positioning systems, and equipped with echo sounders, wave riders and ultra-short baseline positioning equipment, we have established a full-chain marine geophysical equipment system covering "positioning-acquisition-excitation-quality control".
Relying on professional vessels and customized equipment, we provide one-stop services ranging from marine survey, technical adaptation, operation control to community coordination. A standardized and replicable overseas geophysical operation procedure has been established to ensure efficient and compliant implementation of projects.



The West Kangean 3D OBN Project in Indonesia is located in the West Kangean offshore area of Indonesia, a key geophysical project focusing on oil and gas exploration.With the core objectives of "accurate deployment, efficient shooting, and high-quality acquisition", Fengnian Technology provided a tailored full-process geophysical technical support scheme, coordinated and promoted key links including OBN node deployment, airgun shooting, and data quality control, and successfully completed the scheduled geophysical tasks.The project lasted 48 days, with 41 effective working days. A total of 154,532 seismic shots were acquired, with an average daily efficiency of 3,219 shots and an effective daily efficiency of 3,769 shots, and a peak single-day output of 7,242 shots.Despite a 7-day production suspension due to community interference, a 2-day output reduction due to weather, and a 5-day output reduction for equipment maintenance and supply, the core acquisition target was still exceeded.
