Horizontal well refracturing to remain a niche US market
Horizontal well refracturing technologies will likely remain a niche market in the US until
significant technical and financial risks can be reduced, according to new research from IHS. The market analyst estimates that by 2020, refractured wells will account for as much as 11% of horizontal wells fractured in the US. According to IHS, the Bakken has the greatest number of refractured wells in US plays, followed by the Barnett and Marcellus plays. Unsurprisingly, the largest number of refractured wells is located in the plays with the oldest wells.
According to the analysis, three refracturing techniques, including diversion, coiled tubing (CT), or mechanical isolation, were most often employed in the wells studied. However, each method has benefits and limitations, and it is unclear which technique will dominate in the future.
BHP Billiton is writing down $2bn of its assets after pledging to cut $2.4bn in spend on US shale fields in the next 18 months and reduce the number of onshore rigs by 40% in its 2015 financial year.
