Based on a direct comparison of the production performance (left) and completion volumes (right), wells treated using the HiWAY technique outperformed conventional wells by 33% at three months and 38% at twelve months. On average, wells using the flow-channel fracturing technique used 32% less water volume and 37% less proppant volume.

CHALLENGEEvaluate production performance and treatment size of HiWAY* flow-channel fracturing technique versus wells treated conventionally in the Eagle Ford Shale.

SOLUTIONConduct multipart study using data from the IHS Enerdeq (public data source) for more than 11,400 wells completed after October 2010 to understand the differences between wells treated conventionally and the more than 1,100 wells treated using the HiWAY technique, comparing

■ short-term and long-term production ■ incremental production and

incremental revenue ■ overall proppant and water volumes.

RESULTSAchieved significant benefits for wells treated using the HiWAY technique.

■ Outperformed conventional wells both short-term (33% at 90 days) and long-term (38% at one year), on average.

■ Used 37% less proppant and 32% less water volume when compared with conventional treatments.

■ Generated an estimated incremental 50 million bbl of oil equivalent or an additional USD 2.9 billion in gross revenue in 3.75 years from 1,024 Eagle Ford Shale wells treated using the HiWAY technique.

■ Saved an estimated 2.7 billion lbm of proppant and 2.1 billion galUS of water in 4.25 years on 1,146 Eagle Ford Shale wells treated using the HiWAY technique.

In a multipart study conducted over four years on Eagle Ford Shale wells, the HiWAY technique significantly reduced the amount of water and proppant needed during operations, performed better than conventional wells on average, and generated significant additional revenue.

HiWAY Technique Increases Production by 38%, Requires 32% Less Water and 37% Less Proppant Multipart study compares more than 1,100 Eagle Ford wells with flow-channel fracturing treatments versus conventional treatments, resulting in significant savings

Of the more than 11,400 horizontal wells in the Eagle Ford Shale, more than 1,100 liquid- and gas-producing wells have been completed using the HiWAY flow-channel fracturing technique (blue) since October 2010.

The HiWAY technique increased production from 1,024 wells by an estimated 40%, resulting in an estimated 37% increase in gross revenue (USD 2.9 billion) for operators in comparison with conventional treatments.

■ Conventional

A subsequent study using the best six months of data for each year estimated the production for 1,024 wells treated with the HiWAY technique had they been treated conventionally. In addition, a study of 1,146 wells treated using the HiWAY technique through December 2014 estimated water and proppant volumes had the wells been treated conventionally.

The HiWAY technique saved 2.7 billion lbm of proppant on 1,146 wells, resulting in an estimated savings of 39% in comparison with conventional treatments—enough to complete an additional 730 wells treated using the HiWAY technique.
