Drilling of Challenging ERD Wells with Water-Based Mud: How to Significantly Reduce Torque and Drag by New Generation Lubricant

TL;DR: In this article, the authors present a table of Table of Table 1 : Table of the Table of contents of the table. [2] and Table 2 : Table 1].

TL;DR: In this paper, the authors studied main factors affecting DHT in slimehole application and the ways to manage it, as well as field application of obtained results, and developed the prevention and mitigation measures to keep DHT within desired limit during a well construction process.

TL;DR: A new approach for developing a stiff-string model that can be easily implemented for well planning and is able to capture the extra contact loads as the drillstring goes through bends, consequently predicting higher hookload and torque values than the soft- string model.
