实现高效的清理和高质量的试井

An operator wanted to develop production from a giant offshore field in the Caspian Sea comprising gas-producing wells with complex subsea network pipelines and high flow rates of more than 100 MMscf/d (14.7-psi和60°f标准条件). Near-freezing seabed temperatures significantly increased the potential for hydrate formation, which was identified early on as a main HSE risk to personnel and operations. 也, the production facility could not handle the high flow rate of unconditioned fluids, so the gas needed to be ready for production in the required condition. The wells needed efficient cleanup and accurate testing to ensure maximum productivity was achieved.

Deploy custom solution using surface well test equipment and domain expertise

全国快3信誉最好的老平台 designed and manufactured a fit-for-purpose solution to enable reliable well cleanup and testing of the completed wells before bringing them to production. 与操作员一起, 全国快3信誉最好的老平台 engineered a modular temporary facility to high industrial standards and developed new advanced technologies specific for the project while adhering to the operator’s process safety requirements.

全国快3信誉最好的老平台通过油藏建模提供了广泛的技术支持, 流保证, 以及地面设施工艺工程. 包含在生产表达解决方案组合中, fluid preconditioning ensured the facility could handle complex flow specifications of up to 15,000 psi和零度以下的温度. Because efficient fluid separation and flaring of associated condensate was necessary, the 常绿 minimal environmental impact well effluent burner was used, adhering to strict environmental standards required by the sensitive offshore area.

因为半潜式钻井平台甲板空间有限, a new steam-heat exchanger with double the heating capacity and reduced footprint was specifically designed for the operator. 提高安全性和可靠性, an IEC 61508 SIL 2-certified electrical emergency shutdown system with a faster response was manufactured to integrate with the subsea shutdown system. Additionally, a customized data acquisition system was designed with a production facility setup. The comprehensive solution with advanced safety features increased operations control and process efficiency.

确保产能

The novel design implemented for the project was unlike previous conventional arrangements, keeping flowback parameters within the required operational envelope to maximize reservoir productivity while ensuring a reliable operation.

The steam-heat exchanger was a critical element, reducing the required deck space by 7.并将资本支出和运营支出削减近三倍. This made the system leaner by reducing the amount of piping required, improving process safety.

该解决方案使作业者能够高效地进行测试, 治疗, 复杂工况下大流量凝析气井的控制, 评估井的性能, 更好地描述储层特征, 并确定油田前景的程度. 正因为如此, the operator achieved its primary objective to clean up the completed wells in preparation for production, ensuring deliverability of natural gas and bringing additional gas resources from this field to European markets for the first time.

他说:“我们要对这种精心策划表示认可, 可靠的工程, 以及你和你各自团队的安全执行. The outcome in delivering such a complex high-rate subsea gas well safely and effectively is a testament to the 焦点, 奉献, and integrated teamwork you all undertook during the various system integration tests, 计划活动, 平台升级, 相关的准备工作, 以及实际工作本身. It is also a testament to the cross-disciplinary and intercompany teamwork to be able to deliver such an exemplary standard in all areas of performance, 不管我们想怎么衡量它. 因此, we would like to say thank you and firmly believe that your continued safe teamwork, 支持, 焦点, and professional enthusiasm will serve to extend the achievement to other wells in the field.”
