Shell just keeps getting better at Montney natural gas drilling.

The company’s well productivity in the play has improved by approximately 200 percent since 2016, according to a research report this week from Peters & Co.

Shell acquired much of its Montney Groundbirch asset from Duvernay Oil Corp. in July 2008, giving it one of the oldest legacy positions in the Montney. It currently has over 350 producing wells yielding about 520 MMcf/d of natural gas.

Rates have increased by 16 percent in the last 12 months, analysts noted.

From 2012 to 2015, well rates were consistent with initial 30-day flow rates below ~4.0 mmcf/d. This increased to ~5.0 mmcf/d in 2016 as Shell began to drill longer lateral lengths, and averaged ~9.0 mmcf/d in 2017 with 25 new wells coming on-stream.

“Well results have demonstrated a step-change in productivity year-over-year since 2016,” Peters & Co. said.

“In 2017, wells produced over 1 Bcf of gas in the first five months (on average), compared to 10 months for wells brought on-stream in 2016. In 2018, the results have shown a marked improvement again; there are six wells with average lateral lengths of ~3,100 meters that Shell brought on-stream in January (on the same pad).”

These wells have an average initial 30-day natural gas rate of ~12.0 mmcf/d, and produced at an average rate of ~11.7 mmcf/d in month two. Analysts noted that the wells are likely being restricted to have a relatively flat month-over-month profile.
