... of two years laboratory studies show that the of the use of micro-cement to protect the well casing from the corrosive influence of sodium chloride and magnesium sulfate is expedience. The loss of samples strength with micro-cement and without it in sodium sulphate and sodium chloride solutions...

... method that can nondestructively investigate the 3D microstructure of the materials. All prepared cement samples were first characterized by a SkyScan® 1172 Micro-CT scanner (SkyScan LLC, Brussels, Belgium). Considering the high densities of both cement and the casing, a copper plus aluminum filter (Cu...

... affect the cement-rock interface bonding. More specifically, integrity of the cement-rock interface was characterized using micro-computed tomography (CT) and environmental scanning electron microscopy (ESEM). Hollow cylinder rock samples were prepared by using rock samples (e.g., Banff dolostone...

Paper Number: ARMA-2019-0292
... ABSTRACT: Cementing is a major step in the construction and sealing of hydrocarbon wells. During the life cycle of the well, cement is prone to cracking due to change in downhole conditions. This research investigates the use of micro-sized cross-linked polymer gel as a sealant material...

...) and at the cement-casing and the cement-formation interfaces (debonding fractures). Micro-annuli (MA) are the systematic and inter-connected debonding fractures which is the most hazardous mode of cement failure and can cause serious wellbore leakage problems. This paper utilizes the extended finite element method...

... Abstract For the first time in a Danish field, micro-fine cement was used to abandon a multi-zone horizontal well by plugging each sand fractured zone sequentially. Lab testing was performed to investigate the depth of penetration of different conformance systems in a 20/40 sand pack. The micro...

These additives fill contraction induced voids within the cement structure and between the pipe and cement, which leads to an impermeable cement, thus eliminating the existence of micro-fractures and micro-annulus. These materials are economic to use...
