Exploration and Development Plan Providing Excellent Exploration and Development Solutions for Oil Companies Relying on its proprietary technologies and software, the company provides integrated solutions for seismic acquisition design, processing, interpretation, and integrated geological studies for oil companies. Since its establishment, the company has undertaken over 500 research projects, provided exploration and development solutions for different types of oil and gas reservoirs, proposed hundreds of drilling well locations, making important contributions to increasing reserves and production for oil companies, and receiving positive feedback from relevant oilfields. For example, in recent years, it has ranked among the top in partner evaluations byCNPC's Tarim Oilfield. CNPC Tarim Yaha Gas Field: From 2010 to 2018, the company continuously provided development plans (including development well location deployment plans) for the Yaha Gas Field for 9 years. The geological reserves of the Yaha Gas Field expanded by 10.27 million cubic meters, strongly supporting the gas field's development. Furthermore, in the study of the Cambrian sub-mountain exploration in the YH Gas Field, the deployment of wells YH1-3 (2015)， YH3C (2016), and YH105 (2017) led to breakthroughs, thereby opening up a new situation forsub-mountain exploration and development of the YH Gas Field. CNPC Xinjiang Oilfield Branch:"SN Area Rolling Exploration and Development Target Selection and Deployment Plan Study," led to the discovery of the L151 oil reservoir;"Reprocessing and Interpretation of 3D Seismic Data in theSN24-L9 South Well Area" resulted in the deployment of 5 appraisal wells, all obtaining high oil production; "Splicing Processing and Reinterpretation of 3D Seismic Data in the K80-K81 Well Area" led to a breakthrough in well K021 (high oil and gas production); "Processing and Interpretation of3D Seismic Data in the Ma 1 Well Area, Mahu Sag" discovered 9 closures, with a total of 25 wells adopted for drilling and obtaining oil and gas. CNPC Southwest Oil & Gas Field:2021-2022,"Annual Seismic Data Tracking Technical Service for Tight Oil & Gas Exploration and Development Department Projects" completed tracking for over 30 horizontal wells and more than 20vertical/deviated wells, with a100% target hit rate and an average reservoir hit rate exceeding 90%.

Drilling Service Horizontal wells are one of the effective means for the development of low-permeability oil and gas reservoirs, as well as unconventional oil and gas reservoirs such as shale gas and coal gas layers. From 2021 to 2022, one drilling rig of PetroReland Petroleum participated in the development of low porosity and low-permeability oil and gas fields in the Ordos Basin, China; From 2016 to 2022, two 4000 meter drilling rigs and fracturing equipment were organized to participate in the exploration and development of low-permeability oil fields in the JR oilfield in Congo.

Seismic Interpretation and Reservoir Evaluation Seismic interpretation and reservoir evaluation is another key strength of ReLand Company, making it one of the domestic private geophysical service companies with the strongest technical capabilities. The company boasts numerous geological experts and excellent teams with extensive work experience. In recent years, it has completed multiple reservoir evaluation projects in oilfields such as Daqing, Xinjiang, Jilin, Liaohe, Changqing, and Tarim. These projects comprehensively cover the exploration, evaluation, and development phases of oilfields, significantly contributing to the progress of oilfield exploration and development. The company has worked on various basin types, including rift basins (such as the Yishu Graben, Yitong Graben, and Tanan Sag), sag basins (such as the Junggar Basin, Tarim Basin, Songliao Basin, and Ordos Basin), and foreland basins (such as the Kuqa Foreland Basin). Additionally, the company has undertaken multiple projects in volcanic reservoir prediction and gas-bearing detection, developing specialized technologies tailored to different geological targets. The company currently has branch centers in Daqing and Xinjiang, as well as a dedicated project team in Liaohe.
