Going with the grains

Drilling and completions practices have driven demand for frac sand to new highs and threaten shortages in some prime shale regions. But what qualities make a sand suitable for fracking, and where is the industry looking for solutions to supply chain challenges.


Steering toward a common goal

Geosteering requires sophisticated technologies, mounds of data — and co-operation. Yet the teams tasked with drilling unconventional wells are often judged on conflicting performance metrics. However, mutual understanding can help geosteering teams overcome drilling challenges to deliver successful horizontal wells.


Ideas cascade for water management

Operators have always factored water handling into the cost of drilling and production operations. But the proliferation of hydraulic fracturing in North American shale plays has moved water handling from line item expense to central concern.


Digital sentry

More than 100 people may enter and exit a location during unconventional well completions. Information about personnel movement in the field may be as critical to outcomes as the data collected by surface and downhole sensors. Upstream Technology looks at a Houston company’s efforts to capture that missing element in operators’ big data.


Cased collection

Schlumberger has introduced a spectroscopy service that the company says provides the industry’s first complete cased-hole formation evaluation and reservoir saturation monitoring with open-hole logging quality.


High-tech handling

Taking cues from Amazon and Google, two Scottish companies have paired up to create a global intelligence platform for the energy supply chain


Doubling down on digital

A digital twin maintained throughout an asset’s life can help keep the project on schedule during fabrication and anticipate repair needs once it is up and running
