The most common fallacy in the quest for the optimum stimulation treatment in shale plays
across the country is to treat them all just like the Barnett Shale. There is no doubt that the …

Curing temperature has a significant influence on cement paste microstructure and the
properties of its principal hydrate CSH. In this paper, the effect of the hydration temperature …

By combining calorimetric measurements with dilatometry, it has been possible to calculate
the contributions of thermal expansion, pore pressure, and crystallization pressure of ice to …

Microannuli at the well cement-sheath interfaces may result in loss of zonal isolation, which
is the source of many problems, such as sustainable annular pressures, crossflows between …

Interface debonding is considered as a major reason for loss of well integrity of a CO 2
injector. In this work, a 3D numerical model is developed for simulation of a fluid-driven …

Increasing the gypsum and slag contents in the blended cements containing slag is
conducive to promote its green degree. The blended cement was prepared by mixing slag …

The pore structure of mortar (w/c= 0.55) was examined using thermoporometry (TPM),
nitrogen adsorption/desorption (NAD), and mercury intrusion porosimetry (MIP). The TPM …

Tests performed in the laboratory have shown that there exist two types of mechanisms that
could lead to loss of cement-sheath integrity: mechanical degradation, when cement is …

Calcium sulfoaluminate (CSA) cements have lower carbon footprint than that of portland
cement, which makes them a suitable alternative as a sustainable cementitious binder. Early …

In conventional wellbore-integrity analysis, the cement sheath's initial state of stress and
transient thermoporoelastic effects are often neglected. However, the initial state of stress is …
