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 presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

This paper offers an alternative explanation for the early boundary-dominated flow related to dissolution of salt-sealed natural fractures in the shale. -
An analysis studied whether a well's toe could be affecting the production performance.
-
Although early inflow control devices and intelligent completions (ICs) were introduced almost 20 years ago, completion technology has not kept pace with advancements in drilling technology.
-
In the Eagle Ford, an integrated approach to engineering and operations was key to optimize performance and improve understanding of the area.
-
A number of companies are pushing for alternative approaches to offshore development that seek to access marginal reservoirs. Their differing and unique ideas call for a departure from the usual playbook, but share a common goal of slashing capital costs.
-
Larger-diameter coiled tubing recently has been used to perform millouts because of its improved set-down force and increased annular velocities for cleanout purposes. Service companies and operators have reduced the number of wiper trips when using larger-diameter CT, to save time and money.
-
Wellbore position is computed from survey measurements taken by a measurement-while-drilling (MWD) tool in the bottomhole assembly (BHA).
-
Saudi Aramco operates a large offshore oilfield development that has driven achievements in multilateral and extended-reach directional wells.
-
Eight of the world’s 10 longest wells have been drilled by ExxonMobil as operator of the Sakhalin-1 project in Russia.
-
The development of multilateral wells and long-reach wells has become important to maximizing recovery for many fields. These technologies are often applied in offshore environments, where large reservoir areas are drained from one or more platforms.
