Directional/complex wells
This paper aims to establish a set of best practices for generating particle-size-distribution data from core samples.
A shared digital mindset across subsurface, subsea, and drilling and wells is accelerating well planning at Vår Energi.
This paper aims to assess the effectiveness of using advanced integrated production-data-analysis techniques for condensate-rich tight gas fields.

A North Sea field development included installation of long 4½-in. completion liners in the horizontal reservoir sections of each well. To minimize overall risk, the operator planned to use managed-pressure drilling (MPD). -
Few locations present as many challenges for drilling as the Arctic. It is one of the most hostile environments in the world, with some of the most remote locations, the toughest logistics challenges, and the largest gaps in infrastructure on the planet.

This paper describes the first job in southeast Asia in developing horizontal-well placement in a turbidite environment.
-
A new rotary-steerable system (RSS) was designed to give geometrically greater dogleg-severity (DLS) capability while still being able to withstand the increased bending stresses.
-
This paper explores the applications, benefits, and value of a high-build-rate rotary-steerable system (HRSS) capable of delivering dogleg severity (DLS) greater than 18°/100 ft.

Advances made in horizontal and complex-trajectory wells demonstrate that, despite this historic downturn, the industry has kept innovating and optimizing to bring more-efficient solutions to the table.
-
Experience has revealed that frictional pressure loss in the wellbore hinders the full use of the entire length of the horizontal well. This paper presents a new approach to maximize the use of the full length of long horizontal drainholes.
-
This study compares the performance of openhole-packer completion systems with that of cemented-liner completion systems in the northern Montney gas resource play.
-
In horizontal and extended-reach wells in which long completions are run into highly deviated or lateral zones, large compression loads arise because of running friction.
-
In organic shales, hydraulic fracturing is important for optimizing the production of horizontal wells. For a standalone lateral, the propped surface should be maximized to increase production. In the case of a pad, well spacing is an additional factor.
