... Abstract Many gas wells in Adriatic Sea are suffering from both water and sand production. An original sand control polymer technology has been successfully implemented and has proven to be an efficient way to stop sand production and thus maintain gas well under steady production. In many...

The fourth gas well was the first Martin Linge well completed openhole with 250-micron stand-alone sand screens (SAS). The previous Martin Linge gas wells were drilled...

... Abstract The primary aim of the research project was to develop an efficient technology to control excessive water production in gas wells. As a novelty, water sensitive petroleum-based solutions were developed, which spontaneously form extremely high viscosity barrier under reservoir condition...

... required for enhancing productivity of wells in shale gas formations. Due to the shally characteristics of the formation rock, the productivity of the hydraulically fractured gas wells seems to be very vulnerable to the damage by the fracturing fluids. The damaging mechanisms are believed to include fluid...

... of proppant is never indicated. Furthermore, leak-off damage is not important. For the high permeability reservoirs, selection of better proppants and fast ramping up of their injection are keys to the design. For the high permeability gas well, it is necessary to remedy the turbulence effects by changing...

Finally, guidelines on acceptable well deviations that will not lead to screen erosion are offered. gas well hydraulic...
