Information about possible accidents in oil and gas well drilling

Abstract

In the mines indicates an indirect effect on the recovery efficiency of the target material associated with excavation and blast damage. Therefore, drill strings, detonators, and detonators in the mine will be more about the problem of the boundary of the blasting area and create conditions for less drilling. During blasting and drilling processes in mining enterprises the main problem in creating an accurate surface model is that the mass of the cover rock is usually relative to the mass of the blasted area will be widely spaced. Coarse samples are obtained by drilling blast holes. So interpolation sufficiently exceed local variations in the underlying geology. Created in a mine borehole measurement reliable determination of geological boundaries in the field in real time data, we posed a local model estimation problem in an adaptive sampling system. The selection strategy based on the proposed information will consist of two stages. First, blast holes in mines are selected in a way that is adapted to the geology of the drilling and to obtain the maximum benefit in terms of their location.
