Oriental Geophysical Exploration: Wave Blue Brave Tidal Head

Oriental Geophysical Exploration: Wave Blue Brave Tidal Head

In late April, the three teams of the Saudi Offshore Project, the world's largest offshore seismic exploration project undertaken by the Marine Geophysical Branch of the Oriental Geophysical Company, were working smoothly and efficiently in the Arabian Sea. This is a microcosm of the development of Marine OBN business of Oriental Geophysical Exploration Company, which marks the further consolidation of the development advantages of Oriental Geophysical Exploration company in the field of Marine business.

In the process of vigorously implementing the international development strategy, Dongfang Geophysical Exploration Company has always adhered to innovation-driven, strengthened technological research, and sharpened the sword for ten years. The Marine OBN business has achieved a leap-forward development from scratch and from there to excellent, providing a guarantee for comprehensively promoting the high-quality development of Marine business.

In 2014, when oil companies' demand for seabed nodal exploration (OBN) was just budding and most of their peers were still watching, Orient Geophysical Company was keenly aware of the prospect of this technology and quickly made the strategic decision to transition to OBN, and advanced the development of OBN's four core technologies and equipment.

That year, a well-known foreign oil company announced that it would deploy an ultra-high density OBN project, attracting a number of companies in the industry to bid. The Marine Geophysical Exploration Branch of Dongfang Geophysical Exploration Company quickly set up a technical team to carry out research, and quickly formulated and formed a complete set of OBN integration solutions for collection and release, positioning and quality control, which met the requirements of Party A in an all-round, high coverage and large offset, laying the foundation for the project to win the bid.

In the case of not mastering OBN on-site quality control technology and data processing technology, Oriental Geophysical Exploration gave full play to the advantages of integrated technology, collected wisdom to solve problems, and successfully completed the company's first OBN project. The technical team of the Marine Geophysical Exploration Branch quickly completed the development and upgrade of the four OBN supporting software, and achieved the breakthrough of OBN quality control software "from 0 to 1", and the operating ability comprehensively exceeded the competitors. At the same time, the Geophysical Exploration Technology Research Center has made every effort to research OBN processing technology, and has invested more than 30 experts and technical backbone, and finally formed high-quality data processing software, providing strong technical support for this project and other OBN projects in the future.

In order to rapidly develop OBN business, Dongfang Geophysical Exploration strengthened scientific and technological research, accelerated the transformation of technological achievements, and jointly developed GPR subsea node instruments with equipment companies in the industry, further established the position of the main contractor in the global OBN exploration business. The self-developed Dolphin integrated navigation system provides an integrated solution for the integrated navigation and supporting data processing of large seismic exploration fleets. The optimized layout of the shipborne Marine modular Marine node automatic retaking and retaking system can achieve zero obstacles in the global node retaking and retaking operations in medium and shallow waters. Through modular design and carrying the Internet of Things system, it realizes the mechanization, automation and remote intelligence of Marine OBN seismic operations. Independently developed KL-NodeQC quality control software system, its data quality control function and computing performance in the industry leading level; The transition belt technology has greatly improved the efficiency of submarine seismic acquisition and the energy of low-frequency seismic data. In 2022, the world's first large-scale DP shallow water special exploration ship "Innovator" independently developed by Dongfang Geophysical Exploration came out, filling the gap in the industry and taking an absolute leading position in the competitiveness of the global shallow water transition zone, and "OBN seismic exploration technology and equipment innovation" was selected as "Top Ten scientific and technological Progress of China Petroleum in 2022".

This year, Oriental Geophysical Exploration Company won the Qatari four-dimensional OBN project, bp Azerbaijan four-dimensional OBN project, deepwater ROV OBN project in the Gulf of Guinea, etc., opening up a new track for the full chain OBN business. At present, the eight OBN operation teams of the Marine Geophysical Exploration Branch are producing efficiently overseas, and the OBN business has realized the full chain development from the transition zone, shallow water to deep water.

In the past 10 years, the Marine business of Dongfang Geophysical Exploration Company has closely focused on the goal of building a "world-class Marine geophysical technical service team", and vigorously developed OBN exploration, the key core technology to achieve curve overtaking. Dongfang Geophysical Exploration Company has become the only geophysical technical service company in the world with four core technologies at the same time, including navigation and positioning, node acquisition and release, data quality control and data processing. It has built a large number of OBN benchmark projects such as ADNOC in the UAE, bp in Indonesia, Chevron in Nigeria, and Shell in Brunei.

Up to now, Oriental Geophysical Exploration Company's Marine business footprint has spread to more than 70 countries around the world, providing technical services for more than 80 oil companies around the world, leading the OBN business market, completing nearly 30 OBN projects with high quality, and maintaining the world's first OBN market share for five consecutive years. Dongfang Geophysical Exploration has become the most competitive OBN exploration company in the world, and has successfully built the world brand of petrochina's Marine geophysical exploration.
