Consolidation, shift away from dayrate model set to transform US onshore drilling industry


One of the biggest challenges the industry faces right now is the dayrate model. The issue is that the dramatic increases in drilling efficiency and wellbore quality made by drilling contractors are not reflected in the dayrate model. The benefit of those advances goes only to the shareholders of the E&P company, not to the shareholders of the drilling contractor...

Expandable liners enhanced for more precise, reliable refracs


Enventure has launched its enhanced versions of its ESeal RF and ESeal RFHT refrac expandable liners at the 2018 SPE Hydraulic Fracturing Technology Conference and Exhibition, held 23-25 January in The Woodlands, Texas. The Enhanced ESeal RF and ESeal RFHT provide 16% and 45% higher strength, respectively, than the original ESeal RF Liner. This has expanded the operating envelope for installations using higher treatment pressures and in higher temperature reservoirs, which could exceed 300°F. The liners now offer more predictable zonal isolation and better ID preservation, said Matt Meiners, Technology and Product Development Manager at Enventure. The enhancements were made in response to recent surges in refracturing programs as operators seek to increase production and estimated ultimate recoveries of shale wells. Watch ...

Global land rig demand recovers, offshore still seeking inflection point

Figure 6: The active rig count in Canada rose to 155 in 2017, up from last year’s 91. Utilization improved to 24%.

One year after setting record lows for utilization, the land rig markets in North America have seen a remarkable recovery. In the US, onshore rig demand surged by 105% to 976 active units, compared with 476 in the previous year. In Canada, there were 155 active land rigs during the census period, an increase of 65% over last year’s 94 units. Nevertheless, fleet utilization in both countries remain below normal at 46% (US) and 24% (Canada). Many lower-spec rigs are expected to exit the available fleet next year, as operators continue to give preference to higher-specification pad-capable rigs for development of onshore unconventional resources...

Operators double down on Permian, seek solutions to operational, downhole and reliability challenges

A panel of operators with assets in the Permian shared their perspectives and outlook on the challenges and opportunities at the IADC Shale Energy Workshop on 13 September in Midland, Texas. From left are Steve McCoy, Latshaw Drilling (moderator); Mike Hollis, Diamondback Energy; Joe Wright, Concho Resources; John Willis, Occidental Oil and Gas; and Joey Hall, Pioneer Natural Resources.

If the rising rig count has made US shale the brightest spot in the global exploration and production market, then the Permian Basin has been the supernova. Of the 916 rigs working in the US onshore market as of late September, 385 were in the Permian. No other US basin even comes close – the Cana-Woodford in Oklahoma sits in a distant second with only 62 rigs. In fact, the Permian has been a major driver of growth in US oil production since 2010, Joe Wright, Executive Vice President and COO for Concho Resources, said during a panel session at the IADC Shale Energy Workshop in Midland, Texas, on 13 September. He pointed out that US oil production grew by 4 million bbl/day from 2010 to 2017, and 40% of that growth came from the Permian. “You can see that it’s very much been a revolution,” he said...
