Borehole Seismic and VSP Services
Zebra Geosciences Limited 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 firstname.lastname@example.org
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.
Zebra Geosciences have the ability to correctly handle virtually all
types of borehole seismic surveys (single or multi-component) including:
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
- Walkaway VSP Surveys
- Offset Source VSP
- Deviated (or horizontal) Well VSP & Checkshot Surveys
- Rig Source
VSP & Checkshot Surveys
- Shear Sonic Calibration Surveys
- Shear Wave Seismic
- AVO Calibration Surveys
- Borehole to Borehole or Surface
to Borehole Tomography Surveys
- VSPs for Anisotropy Analysis
- VSPs for Q
- VSPs for Surface Seismic Phase Determination
- VSP Inversion
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.
The principals of Zebra Geosciences 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.
