Extended reach wells - PetroWiki
2016年7月27日 · An extended-reach well is one in which the ratio of the measured depth (MD) vs. the true vertical depth (TVD) is at least 2:1. Extended reach wells can be extremely long (measured depth) and relatively shallow vertically, as well as relatively short and very shallow vertically - and everything in between.
Extended-Reach Drilling (ERD)—The Main Problems and Current …
2023年3月23日 · Drilling a horizontal extended-reach well (ERW) with the shortest time is of great significance for drilling safety, reducing or eliminating reservoir damage, efficiency and economic benefits . This technology enables access to a new energy source that was previously technologically challenging to exploit, such as natural gas hydrate [ 11 ].
Technology Focus: Horizontal and Extended-Reach Wells
2019年11月1日 · Drilling a horizontal well now involves a combination of various and complex technologies and variables that need to be controlled or operated almost at the same time. To overcome friction along these long wells, downhole and surface-oscillation tools are combined to transfer the most weight to the bit.

Wells with horizontal departures in excess of 40,000 feet (12 km) at vertical depths of less than 10,000 feet (3 km) are now being actively considered as a viable way of accessing satellite reserves from existing facilities or, in the case of environmentally-sensitive arctic environments, to develop offshore fields from onshore locations.
Limit analysis of extended reach drilling in South China Sea
2009年5月8日 · Extended reach wells (ERWs), especially horizontal extended reach well with a high HD (horizontal displacement) to TVD (true vertical depth) ratio, represent a frontier technology and challenge the drilling limitations.
Open-hole extension limit of offshore extended-reach well …
2024年7月6日 · In this paper, prediction models of open-hole extension limit of offshore extended-reach wells considering formation collapse, ROP, and annular pressure loss are established and analyzed with two extended-reach horizontal wells, and the following conclusions are derived: 1.
