1. A method of displaying streaming video on an electronic tablet in a way that realizes an immersive viewing experience, comprising the steps of:
- downloading an edited moving video file in a compressed format comprising a set of pixel data representative of a subject area field of view (FOV) first captured as raw video data using a digital SLR camera affixed with a hemispheric lens;
displaying a framed portion of the edited moving video file, said framed portion comprising a default FOV defined by a subset of the pixel data representative of the subject area FOV; and
in response to user input, modifying the pixel data content of the default FOV being displayed to convey an appearance of panning.

Abstract
A method of opening productive formations by slot-perforating, includes providing a working fluid which contains water, and abrasive component, and an additive; supplying the working fluid at a high pressure towards a formation so as to cut slots and to provide an inflow of oil, gas or hydro-geological liquid from the formation into a borehole; and using as the additive-ethylene glycol so as to reduce density of the working fluid and therefore to increase a speed of jet of the working fluid due to increase of kinetic energy of particles of the abrasive component.

13. A system for creating and displaying streaming video on an electronic tablet such that a viewer of the streaming video appears immersed in a subject area within which the streaming video was captured, comprising
a digital SLR camera with an ultrawide hemispheric lens for capturing moving image data over a substantially convex semi-spherical field of view within the subject area; -
means for electronically converting the captured moving image data to a streaming video file; and an electronic tablet configured for receiving and displaying a portion of the received streaming video file comprising a default field of view (FOV), wherein a content of said received streaming video file defined by said default FOV is modified by panning or tilting the electronic tablet. - View Dependent Claims (14, 16, 17)

15. The system as set forth in claim 15, wherein scenes corresponding to said default FOV are seen by a viewer as if he or she is located in a focal point of a substantially concave semi-spherical surface.

18. An electronic tablet comprising means for receiving and displaying a portion of a streaming video file comprising a default field of view (FOV) formatted to appear as if projected on an inner surface portion of a hemispheric shell, the streaming video file electronically converted from streaming image data captured by a digital SLR camera with an ultrawide hemispheric lens in a substantially convex, semi-spherical field of view (FOV), and means for modifying the default FOV within the streaming video file by panning or tilting the electronic tablet.
