The drive towards cleaner energy resources and energy security policies is promoting the development of a wider range of oil and gas reserves, such as fracking, in very remote locations. However, the loss of methane gas which is associated with these energy resources has a potent greenhouse impact on the environment that is far worse than carbon dioxide, which has been given much attention in recent years. To reduce the loss of methane into the environment from the equipment used in oil and gas extraction it is necessary to have an effective leak monitoring system to enable operators to spot leaks as they arise and take rapid action to fix them to minimise the release of methane into the atmosphere. Present methods of leak monitoring rely on a tedious, resource intensive manual process of sending an engineer to site with a hand held gas leak detector. This is particularly problematic when monitoring a very remote location, which is increasingly the case for newly developed oil and gas reserves.The use of laser beams from an autonomous system to scan a wide area has proven be an effective method for detecting gas leaks in oil and gas facilities, as it has the required sensitivity to detect small leaks and locate them precisely. Compared to current methods of manual surveying such "open path" laser instruments provide continuous 24/7 monitoring which enables much faster and efficient response to repairing gas leaks than would otherwise be possible. If these are not detected they could continue unabated until the next survey, which may be as infrequent as an annual basis for some sites. It also allows the methane mass emission rates to be continuously monitored, which is necessary to support the implementation of legislation to regulate greenhouse emissions from such oil and gas sites. The same laser technology can be applied to other sources of greenhouse gas emissions such as landfill and agricultural sites.Despite the great potential of this laser technology it is not yet suitable for long term unsupervised deployment in remote locations. The barriers to this for commercially available open path laser instruments are the high electrical power requirement, instrument size, and reliability of the laser beam alignment. MIRICO's LOLIPOP project is designed to address these limitations by developing the technology to enable a low power, easier to deploy instrument to be developed for commercial use in these applications

清洁能源和能源安全政策的推动正在促进在非常偏远地区开发更广泛的石油和天然气储备，例如水力压裂。然而，与这些能源相关的甲烷气体的流失对环境造成的温室效应远比二氧化碳严重，近年来备受关注。为了减少石油和天然气开采设备中甲烷向环境中的损失，必须有一个有效的泄漏监测系统，使操作员能够在泄漏发生时发现泄漏并采取快速行动进行修复，以最大限度地减少甲烷向大气中的释放。目前的泄漏监测方法依赖于繁琐、资源密集的手动过程，即派遣工程师携带手持式气体泄漏检测器到现场。当监测非常偏远的位置时，这一点尤其成问题，对于新开发的石油和天然气储量来说，这种情况越来越多。事实证明，使用来自自主系统的激光束扫描大范围区域是检测石油和天然气设施中气体泄漏的有效方法，因为它具有检测小泄漏并精确定位所需的灵敏度。与当前的手动测量方法相比，这种“开放路径”激光仪器提供连续的 24/7 监控，与其他方式相比，能够更快、更有效地响应修复气体泄漏。如果没有检测到这些问题，它们可能会继续有增无减，直到下一次调查，对于某些站点来说，下一次调查的频率可能与每年一次的调查一样少。它还可以连续监测甲烷质量排放率，这对于支持实施监管此类石油和天然气场所温室气体排放的立法是必要的。相同的激光技术可以应用于其他温室气体排放源，例如垃圾填埋场和农业场所。尽管这种激光技术潜力巨大，但它尚不适合在偏远地区长期无人监督部署。商用开路激光仪器的障碍是高电力要求、仪器尺寸和激光束对准的可靠性。 MIRICO 的 LOLIPOP 项目旨在通过开发技术来解决这些限制，以实现低功耗、更易于部署的仪器，以供这些应用中的商业用途开发
