Dewatering involves reducing level of flooding field by various technical measure. This paper studies the methods dewatering involving measure water from surface quarries with help horizontal drilling. Horizontal drilling does not cause discomfort at exploitation works, transport and storage deposits being a very efficient method. has great advantage both in terms efficiency environment because...

In the recent years horizontal drilling (HD) has become increasingly important in oil and gas exploration because it can increase the production per well and can effectively rework old and marginal vertical wells. The key element of successful HD is accurate navigation of the drill bit with advanced measurement-while-drilling (MWD) tools. The size of the MWD tools is not significantly restricte...

Abstract Information about the absolute stress state in upper crust plays a crucial role planning and execution of, e.g., directional drilling, stimulation exploitation of geothermal hydrocarbon reservoirs. Since many these applications are related to sediments, we present refined geomechanical–numerical model for Germany with focus on sedimentary basins, able predict complete 3D tensor. The la...

Traditionally, horizontal cleavage meniscus tears have been associated with osteoarthritis, indicative of the degenerative process. Recent treatment measures have focused on maintaining as much meniscal tissue as possible, despite the routine extension of these tears into the central white-white zones. In the absence of tunnel drilling for cruciate ligament reconstructions, the use of an exogen...
