Marine seismic vibrators are generally considered to be less intrusive than airguns from an environmental perspective. This is because they emit their energy spread out in time, rather than in a single, high‐intensity pulse. There are also signific

Marine seismic exploration involves the use of airgun source arrays for emitting sound energy into the earth. In this paper, we discuss the benefits of using a new airgun design in marine seismic exploration, by way of the reduction in risk of potent

We have developed a new air-gun that optimizes the useful seismic output while limiting any environmental effects from unnecessary high-frequency emissions. We regulate the output at the air-gun’s ports by controlling the motion of the mechanical c

The high-frequency sound emission from air-guns is of no benefit to imaging. Historically, the design goal for airguns was for ever-higher peak pressures and this has led to pulses with unnecessarily steep rise times. The new design (Figure 1) releas

A three-phase transformer with flat conductor layers is proposed in this article. This arrangement is used for high current density transformers. Cost effectiveness in planar magnetic are related with the optimization in the number of layers in each

Fracturing is an important technique for stimulating production in low-permeability formations, and requires special consideration in designing the preceding perforating job. Aligning the perforations along the direction of maximum geological stress,
