Drillability evaluation and spatial distribution characteristics of Fengcheng Formation shale in Mahu Sag

Thermal Science
This study investigates rock drillability characteristics and spatial distribution patterns to optimize drilling efficiency. Laboratory testing of core samples from six wells provided comprehensive mechanical data, including uniaxial compressive strength (147.81-306.82 MPa), triaxial compressive strength (310.56-785.00 MPa), and drillability indices (6.

BARITE SAG UNDER DYNAMIC AND ELEVATED TEMPERATURE CONDITIONS: EXPERIMENTAL STUDIES AND MATHEMATICAL MODELING [PDF]

, 2019
Barite sag is an undesired occurrence that causes density variation in the wellbore. It is a problem that is related to both fluid property (mainly rheology) and drilling practices, and it arises mostly in invert emulsion muds.
