Avalon Sciences Ltd (ASL) designs and manufactures advanced borehole seismic equipment for Vertical Seismic Profiling (VSP), permanent/passive seismic monitoring, well/reservoir characterisation and hydraulic fracture event detection.
Avalon has been at the cutting edge of borehole seismic technology innovation, design and manufacturing for over 20 years. A household name in VSP and downhole microseismic equipment, Avalon Sciences is dedicated to providing the best bespoke solution to meet the client needs whilst providing the greatest possible customer service and support, remotely and onsite.
To deliver this Avalon has invested heavily in a dedicated R&D facility: the Avalon Research Centre (ARC). The ARC is equipped with specialist staff and equipment to ensure continuous innovation for instrumentation within the harshest of well conditions. ASL holds the ISO 9001 award for quality of its design and manufacture processes. Research and Design has been augmented further with the acquisition of a deep well test facility in Cornwall, UK.
At Avalon we have a dedicated Global Operations Team distributed across a number of support sites including, Houston (US, Mexico and Canada), UK (Europe), Abu Dhabi (Africa & Middle East), Beijing and Singapore (Far East).
From these locations our experienced field personnel are able to offer 24/7 technical support, sale and rental services, repair and maintenance, as well as onsite consultancy and training.
The domain of borehole seismic exploration is fast approaching a new era of technological advancement. The increasingly challenging dynamic requirements for mapping and monitoring mean that more complex and hostile well environments now dominate shallower, more conventional hydrocarbon reservoirs.
The deployment of seismic recording systems within wells, to acquire high resolution data, has become common practice over the last few decades. This well-established method of downhole recording, known as Vertical Seismic Profiling (VSP), is dominantly used to complement surface seismic surveying by providing noise reduction and immunity from the distorting effects of near-surface rocks, especially sediments. This allows for much higher resolution imaging between lithologies proximal to the well, whilst also revealing subtle impedance changes even beyond total depth of the exploration well.
At its most basic application, ‘check shot’ borehole seismic calibrates for any inferred depth uncertainty presented by surface seismic, giving an enhanced velocity model around a well. However with new directional drilling technology and instrumentation innovation, access to more complex and deeper environments (e.g. within subsalt zones) has become increasingly available, giving rise to intricate 4 dimensional seismic mapping and extra sensitive hydraulic fracture event detection.
