On the basis of these case studies he proposes a newtheory of power in the information age based on the management of communication networks. Horizontal Directional Drilling Process Knowledge of the directional drilling process by the reader is assumed, but some review may be of value in establishing common terminology. The vertical line is always parallel to the direction of earth's gravity. In fact, even in a vertical well, it might be necessary to deviate to avoid a geological formation or a previous stuck pipe, then return to the original path. North is represented as 0° or 360°.

Directional drilling is the process of directing the wellbore being drilled along a defined trajectory to a predetermined target. The pipeline is prefabricated at the end of the bore opposite the drill rig. In one example, the system receives feedback information from a drilling rig and calculates an estimated position of a drill bit in a formation based on the feedback information. of Drilling, Transport and Oil & Gas Production, Mining and Geology U., Sofia, Bulgaria Directional diamond drilling (DDD) is powerful technology in the service of the mineral exploration industry. Perhaps the most common application for directional drilling More economical to drill a number of directional wells from a single platform than to build individual platforms for vertical wells North sea platforms: Capability to drill as many as 60 wells from a single structure. Sol'n: -ve sign indicates west declination. Provisory - 06 Dec 96 Confidential Directional Drilling 1-1 f Introduction Many legal entanglements developed when it was established through directional surveys that oil was being removed from a productive zone under the tidelands, the ownership of which was claimed by both the town of Huntington Beach and the State of California. HDD construction is considered suitable for large river crossings, extreme congestion (e.g. directional drillingremovethe field/industry that encompasses the act of drilling a section of wellbore that is intentionally oriented non-vertically; horizontal drilling is a subset of directional drilling.

In directional drilling, location of the well is specified by 'Inclination' (or Angle) and 'Azimuth' (or Direction) and these measurements are taken w.r.t a fixed reference system, so that the course of well bore can be exactly calculated and recorded. 0000032537 00000 n Advances in geomagnetic referencing now allow companies to use In directional surveying there are three azimuth reference systems, namely; is the direction of geographic north pole which lies on the Earth's rotational axis. 0000002877 00000 n In the past, high-accuracy guidance methods required a halt in drilling to obtain directional measurements. Pipelines as long as 5,000 ft and sizes of up to 36 inches have been reported to be installed using HDD (Duyvestyn, 2014).
