Vertical Seismic Profile (VSP) is a technique of seismic measurements used for high resolution seismic imaging. It can also be used for correlation with surface seismic data providing velocity information and information for processing such as deconvolution parameters. The defining characteristic of a VSP is that the detectors are in a borehole.
VSP (Vertical Seismic Profile) is the main link between time-based surface seismic imaging and depth/based well logs. It provides a high-resolution image of the structure in the vicinity of the instrumented well. One or several seismic sources on the surface are fired and recorded by the downhole receivers (GEOREC) positioned at different depth ...
The area had little well control and the surface seismic data suffered from limitations owing to acquisition geometry; therefore, the well was targeted for Vertical Seismic Profile (VSP) acquisition. The main objective was to provide high resolution imaging along the top carbonate structure to help better understand or resolve the conflict ...

The Impulse Generator IPG5000 (formerly named IPG1005) is the high voltage supply to the seismic borehole sources BIS-SH and SBS42. This generator is applicable for seismic tomography and crosshole tests in depths greater than 60 m. The energy is stored in a large capacitor bank, which discharges through a mechanical switch.
Dr. Bob Hardage, one of our colleagues, recently shared a remarkable story that highlights the history of Vertical Seismic Profiling (VSP). Bob has been both a researcher and proponent of the technique since its inception in the mid-50's.

Vertical seismic profile. INTRODUCTION. A vertical seismic profile (VSP) survey involves placing sensors in a borehole . to record the passage of energy transmitted us. ing a source of seismic energy . placed on the surface. The sensors are usually contained within sondes that are coupled to the borehole wall using mechanical clamps.
Zero-offset vertical seismic profile (VSP) data were acquired by both retrievable (wireline) geophones and distributed acoustic sensing (DAS) on cemented-in fiber-optic cable. Side-by-side comparisons of these data sets are shown at several steps in the processing flow to help understand the advantages of each of these data types.

In some reservoir applications, seismic data are acquired with downhole sources and receivers.If the receiver is stationed at various depth levels in a well and the source remains on the surface, the measurement is called vertical seismic profiling (VSP). This technique produces a high-resolution, 2D image that begins at the receiver well and extends a short distance (a few tens of …
