Hydraulic fracture stimulation is proven to be the economic way to develop tight unconventional reservoirs. From an operational perspective, hydraulic stimulation is well established and widely applied to most unconventional plays. There is still room for improvement, however, to increase the efficiency and deepen the understanding of the detailed mechanism in the pro…

A leaner and wiser Weatherford seeks new Middle East contracts while growing margins and market share on existing business.

The papers that I included this month demonstrate real measurable efficiency gains and advantages, often processing volumes of data that previously could not be managed by conventional means. Performance measurement and drilling automation are two such examples, and the papers referenced this month, both as synopses and listed for further reading, fall into this categ…

This paper presents a physics-based approach to predict sand production for various reservoir and completion types, explored through a case study of recent production wells in a sandstone reservoir development.

The authors of this paper develop a model that can predict well-risk level and provide a method to convert associated failure risk of each element in the well envelope into a tangible value.

This paper describes sand-control design and execution techniques applied to four high-rate gas wells in a deepwater environment.

This paper discusses novel acoustic techniques used to identify productive zones and areas of sand production in a well with a sanding event.

When Occidental Resources switched to bigger fracture designs to produce more oil, it produced more water as well. Based on research done since, they cannot have one without the other, and at the oil prices recently seen, that’s OK.

The authors of this paper demonstrate that future produced-water management and scale-mineral control may need to consider the sequential exposure effect of steel, cement, and shale on fluid chemistry and mineral precipitation.
