Effect of buoyancy and inertia on viscoplastic fluid-fluid displacements in a regular and an irregular eccentric annulus
(Peer reviewed; Journal article, 2020-09)Casing strings and liners are important subsurface structural components in petroleum and in geothermal wells. After the casing string has been run in hole, it is cemented to the formation by pumping a sequence of spacer ... -
Experimental Study of Hydraulic Sealability and Shear Bond Strength of Cementitious Barrier Materials
(Peer reviewed; Journal article, 2021-06)In this experimental study, two different cementitious materials, including (i) a class of expansive cement currently used for plug and abandonment (P&A) operations and (ii) a non-cement-based naturally occurring rock, ... -
Fluid Migration Characterization of Full-scale Annulus Cement Sections Using Pressure-Pulse-Decay Measurements
(Peer reviewed; Journal article, 2021)Fluid migration behind casings is a well integrity problem that can result in sustained casing pressure, undetected leaks to the environment, and potentially very challenging remediation attempts. Understanding the geometric ... -
A solution for funding the development of technology in oilwell drilling
(Peer reviewed; Journal article, 2020-11)This article proposes a novel methodology to solve an existing gap in benchmark definition by the adoption of statistically defined benchmarks as references to test products or technical procedures. In a win–win partnership, ...
