Borehole Seismic and VSP Services
Zebra Geoscience is a privately funded
company whose focus is on borehole seismic, especially VSP surveys.
The main services offered are described briefly below. More details
on any of these services can be obtained by e-mail enquiry to info@zebrageo.com
Survey Planning
Zebra do not provide a data acquisition service and consequently when
planning surveys can offer impartial advice on "best for well"
technology rather than being constrained by in-house equipment. With
personnel who have more than 20 years VSP data acquisition experience
in virtually all environments, we are able to advise what is physically
practical in addition to what is geophysically desirable.
Survey Field QC
Zebra can provide personnel to travel to the well site and observe the
survey in progress. This has proved useful on many occasions where a
problem has arisen at the last moment and only experienced personnel
can assess its significance.
Survey Processing
Zebra Geoscience has the ability to correctly handle virtually all types
of borehole seismic surveys (single or multi-component) including:
- Walkaway VSP Surveys
- Offset Source VSP Surveys
- Deviated (or horizontal) Well VSP & Checkshot Surveys
- Rig Source VSP & Checkshot Surveys
- Shear Sonic Calibration Surveys
- Shear Wave Seismic Profile Surveys
- AVO Calibration Surveys
- Borehole to Borehole or Surface to Borehole Tomography Surveys
- VSPs for Anisotropy Analysis
- VSPs for Q Derivation
- VSPs for Surface Seismic Phase Determination
- VSP Inversion
In almost all cases, we are able to re-process VSP data bringing the results
up to modern standards and making these data available for loading to
an interpretation workstation even when the original data exists only
on paper or on archaic magnetic media.
Reporting
When preparing our reports, it is Zebra's policy to provide annotated
displays that highlight all the salient features in a data set. We also
give an undertaking that everything (all plots, graphs, tabulations, etc)
will be provided in digital format so these data can be readily incorporated
into existing projects or presentations.
Interpretation
The personnel at Zebra Geoscience each have more that 20 years experience
of working with VSP data and are available to assist in helping to understand
VSP data. Alternatively, for further independence, Zebra are in contact
with several consultants (ex-oil company personnel) who understand these
data and we would be pleased to arrange introductions. We know this is
in our longer-term interest as; the more benefit that is derived from
VSPs, the more this powerful tool will be used and hence a greater demand
for our specialist services.
