Flow-channel creation for two wells
Petrohawk chose to implement Schlumberger HiWAY flow-channel hydraulic
fracturing technique to address these challenges and improve well performance
for the stimulation of wells in the Hawkville field.
Two wells were selected to build an initial assessment: Heim #2H well,
located in a gasproducing window of the field, and Dilworth #1H well, located
in a condensate-producing window of the field. Results were compared with those
from valid offsets previously stimulated by using conventional techniques.
Rather than leaving fracture flow dependent on proppant pack
conductivity, the HiWAY fracturing technique created stable channels for
hydrocarbons to flow through, thus increasing the effective stimulated
Outstanding production results
The enhanced stimulation of the reservoir provided by HiWAY channel
fracturing gave the Heim #2H well a maximum initial rate of 14.5 Mcf/d, or 37%
higher initial gas production than the best comparable offset well. The HiWAY
technique gave the Dilworth #1H well a maximum initial rate of 820 bbl/d, or
32% higher initial oil production rate than the best comparable offset.
Production rates and wellhead pressures for these two wells remain the highest
among all wells in their corresponding areas.
In a recent press release, the results of the HiWAY technique were
mentioned by Petrohawk: “In Hawkville Field, a new frac design has
significantly improved the Company’s EUR estimates. . . . Two wells with
sufficient production history to estimate EUR’s are the Heim #2H, which is
projected to produce an estimated 8.9 Bcf and 260 Mbngl, and the Dilworth #1H,
which is projected to produce an estimated 2.1 Bcf and 400 Mbc and 208
Based on these results, Petrohawk has increased its utilization of
Schlumberger HiWAY technology and has requested the deployment of an additional
fracturing fleet in the Hawkville field. Six more wells have recently been
completed, showing production trends consistent with the initial test
