Sigra Pty Ltd

Field Service providor for measurement of stress, permeability and coal seam gas contents. Providor of Engineering design and equipment manufacturer in the fields of Coal Seam Gas, Mining, Shale Gas, Civil Engineering, Groundwater, and Drilling.Specialised laboratory service for coal seam gas and rock mechanics.Sigra has a broad skill base and extensive experience for consulting in Mining and Civil Engineering, Geo-science, Hydrology, Mathematics and Programming. Sigra is a regular presenter at Industry forums through AUSIMM, SPE, ACG and Civil Engineering to increase the knowledge base of the engineering profession.Sigra is a privately owned company that supplies services and products in the fields of:Coal Seam Methane CBM,Shale Gas,Groundwater,Mining,Civil Engineering,Drilling.Sigra solves complex problems requiring a wide range of specialist abilities. To achieve this, it has a broad skill base which includes:Engineers – Chemical, Civil, Electronic, Geotechnical, Mechanical, Mining, and Petroleum;Geoscientists, Hydrogeologists, Mathematicians, and Programmers;Accounting and Managerial Staff with both international and domestic experience.Sigra designs and manufactures a range of products, from electronic instrumentation such as field data acquisition and control systems, to heavy items such as blow out preventers used in gas drilling operations.Sigra is an innovative company which has developed a wide range of new equipment and techniques both to service clients and develop new technologies. Approximately 25% of Sigra’s annual budget is expended on research and development, effectively maintaining its position as industry leader. Sigra commenced operations in 1994. Although head office and manufacturing are currently located 30 minutes from the Brisbane CBD in Acacia Ridge, our field engineers operate worldwide.Reservoir Characterisation – Sigra covers all aspects of field and laboratory testing, monitoring, geology and modelling. Using a wide range of techniques and equipment to measure gas content, permeability and stress, Sigra can evaluate how these will change with production.Drilling and Completion – Sigra manufactures blow out preventers and external casing packers. Sigra also provide a well design service which includes torque and drag modelling for directional wells.Production – Sigra supplies well head and reservoir monitoring equipment and separation systems.Coal MiningGas drainage – Sigra has the capability to determine the need to drain strata of gas from the perspectives of outburst control and ventilation. Sigra employs techniques and equipment to achieve this from either surface or underground. A gas drainage system is then designed using appropriate techniques to ensure a safe and successful implementation.Rock Mechanics – Sigra measures stress in rocks using a proprietary overcore system, hydrofracturing or borehole breakout techniques. Strata properties are measured and the stress is calculated throughout the entire stratigraphy using tectonic strain theory. The effects of mining are predicted and consequently monitored to ensure safety. Sigra also design and monitor roof support systems and coal pillars. The monitoring is done via remote instrumentation installed underground or from the surface.Groundwater – Sigra evaluates the effects of mining on groundwater and vice versa.Mine water drainage or groundwater control systems are designed, including re-injectionto maintain and control drawdown using Sigra instrumentation and remote monitoring capability.Civil Engineering.
