Special Issue Information

Dear Colleagues,

Physics-based modelling and representative experiments are fundamental to studying the subsurface, particularly oil and gas reservoirs.  To consider the conditions in the subsurface and their influence on production and well integrity as well as the time frame over which a well is producing, simulations offer a way to extend our understanding of experimental results and gain results at the appropriate time frame.

Modelling and experiments, from pore-scale to reservoir-scale, related to unconventional resources especially focused on increasing production and maintaining production, including ensuring wellbore integrity and isolation of produced fluids, are most desired. All works related to experimental and modelling of fluid flow, heat transfer, consideration of the fracture network, and reservoir engineering are welcomed.

Gas migration in oil and gas wells is defined as gases and/or fluids from adjacent formations invading a freshly cemented annulus. During well completions, gas and/or fluids can migrate to zones with lower pressure or even to the surface. Static gel strength (SGS), related to the yield stress of the cement, is a widely accepted measurement used to predict and minimize gas migration. In this review article, we look at the mechanisms and some possible solutions to gas migration during oil and gas well cementing. The use of static gel strength (SGS) and experimental measurements for SGS and wellbore pressure reduction are discussed. Rheological properties, including the yield stress and the viscosity of cement slurries, are also briefly discussed. Understanding the rheological properties of cement is complex since its material properties depend on cement type, as well as the shape and size distribution of cement particles. From this brief review, it is evident that in order to reduce free water and settling of the cement particles, to lower fluid loss, and to develop compressive strength in the early stages of cementing, an optimal cement slurry design is needed. The SGS test is a standard method used in estimating the free water in the well and could be a reference for gas migration reduction for oilwell cement slurries. Full article
