Parker Geophysical Consulting LLC
Providing expert support to the global energy industry
A recognized industry expert with global experience in all project phases across all survey types for multiple applications of Borehole Seismic
Oil & Gas
Insight to well spacing, landing depth, stage spacing and completion strategies. Structural mapping and bypassed pay. Parent child relationships and production inconsistency.
EOR applications to map CO2 and steam development.
Mining
Borehole seismic can assist with ore pod characterization, disused cavern identification and sub surface storage assessment. It has been successfully used at, amongst others, Potash, Diamond, Uranium and Coal sites
Geothermal
Monitoring programs using borehole seismic techniques are used to provide high resolution reservoir imaging throughout the development of the field.
Engineering
Applications include shallow subsurface mapping related to structural integrity and underground repositories. Delineation of faults, collapse features and unconsolidated zones relevant to engineering projects.
Why consider a borehole seismic survey
All borehole seismic surveys have one thing in common - better resolution than the equivalent surface seismic. This improved resolution is a consequence of higher frequency content as a result of the seismic source and/or receivers being in the well and the consequent reduction in the length of the seismic raypath. Borehole seismic methods and techniques can be utilized to address many typical geoscience challenges faced by operators.
Resolution Challenges
Zhang et al, 2002, CSEG Recorder,
Understanding Reservoir Architectures at Christina Lake, Alberta with Crosswell Seismic
Imaging.
Crosswell tomography provides high resolution seismic reflection and velocity images between wells. These can illuminate structure such as faults and stratigraphy such as mudstones and clays that could inhibit steam chamber development or CO2 saturation.
Characterization Challenges
Marques et al, 2011, SEG, VSP survey assists in the characterization of deep-water turbiditic reservoir offshore Brazil.
The high resolution VSP image illuminated faulting beneath the resolution of the existing surface seismic and facilitated a reevaluation of the lateral variability of the reservoir.
Development Challenges
