This project aims to develop foam assisted continuous gas circulation for dewatering new and existing coal seam gas wells. The potential benefits of this new method include enhanced gas production, better well control, reduced costs and better environmental effectiveness. The proposed solution eliminates the need for mechanical pumps which are currently used for dewatering, and which fail regularly due to gas and solids accumulation within the production wells. Continuous gas circulation could achieve significant savings in downtime and maintenance costs. In addition, reducing onsite maintenance will minimise access requirements for maintenance rigs which disrupt rural activities where the wells are located, thus easing local traffic and reduce the environmental impacts that are associated with well workovers.

该项目旨在开发泡沫辅助连续气体循环，用于新的和现有的煤层气威尔斯井排水。这种新方法的潜在好处包括提高天然气产量、更好的井控、降低成本和更好的环境效益。所提出的解决方案消除了对机械泵的需要，该机械泵目前用于脱水，并且由于生产威尔斯内的气体和固体积聚而定期失效。连续气体循环可以显著节省停机时间和维护成本。此外，减少现场维护将最大限度地减少对维护钻机的访问要求，这会破坏威尔斯所在地的农村活动，从而缓解当地交通，减少与修井相关的环境影响。
