Technical Advantages

HILONG operates an industry-leading joint technology R&D center capable of independently developing cementing additives and composite novel materials. We provide engineering design, technical consultation, and construction services for high-temperature high-pressure wells, ultra-low temperature wells in polar regions, coalbed methane wells, geothermal wells, shale oil and gas wells, wells with severe loss issues, narrow window stratum cementing, and large displacement horizontal wells. Our tailored “one-stop” cementing solutions are customized based on the geological characteristics of each well. Our complete set of API-standard cement slurry testing equipment includes: high-temperature high-pressure fluid loss meters, high-temperature high-pressure consistometers, six-speed rotational viscometers, pressure testing machines, pressurized curing chambers, and static gel strength analyzers.
