S/01
Survey evaluation & design
Bin size, fold, offset range and azimuth distribution are modelled against the target depth and the terrain the spread has to cross. The output is a geometry, a terrain plan and a realistic production rate.
Home / Services
Survey & geophysics, end to end.
Comprehensive seismic services from designing and acquiring seismic surveys through to processing and interpreting the result.
S/02
Land seismic data acquisition
2D, 3D, 3D-3C, 4D and 4D-3C recording on Sercel 428, ARIES and nodal systems, with wholly owned fleets of vibrators and geophysical recording equipment.
S/03
In-field data processing & QC
Field processing centres travel with the crew, so noise, statics and coverage problems are found while the spread is still live and can still be fixed.
S/04
Seismic data processing
QC field processing and office-based processing on ProMAX, carrying the field data through statics, velocity analysis, noise attenuation and migration to an interpretable volume.
S/05
Uphole & LVL surveys
Near-surface velocity from upholes and low-velocity-layer refraction gives the static corrections that decide whether a deep reflector images sharply or smears.
S/06
RTK survey & shallow geophysics
Real-time kinematic GPS positions every station, and shallow geophysical and shallow-water surveys extend the work to engineering, groundwater and transition-zone programmes.
Geometry
Every trace is a ray that went down and came back.
A source point sends energy into the ground; each receiver records what reflected off an interface and returned. The common midpoint between a source and a receiver is the place on the reflector that trace illuminates — and stacking many of them is what turns noise into an image.

Why it matters
Resolution is a decision made in the field.
The bandwidth a crew records sets the thinnest bed an interpreter will ever resolve. Move the dominant frequency below and watch two closely spaced reflectors merge into a single event.
Synthetic trace
Ricker wavelet convolved with a layered reflectivity model
A zero-phase Ricker wavelet at the dominant frequency you set, convolved with an illustrative impedance log and displayed as a variable-area wiggle — the convention on every land seismic section.
