Background
As an alternative to drilling new wells, an operator wanted to test the economic feasibility of refracturing its older gas wells in the Haynesville Shale to recover previously difficult-to-access reserves without adding new drill rigs. The operator decided to evaluate Broadband Sequence fracturing service to determine whether the service could help overcome the technical hurdles of wellbore diversion to optimize production and increase revenue from existing wells.

Operator Uses BroadBand Sequence Service to Boost Flowing Pressure by 300%

Fracturing service used to restimulate previously fractured well, access new rock, and increase revenue, enabling a production increase of 4,900 Mcf/d

After employing refracturing screening analysis to select a well, Schlumberger used Broadband Sequence fracturing service to restimulate a lateral with 10 proppant stages separated by 9 composite pills. As a result, production increased from approximately 100 Mcf/d to 5,000 Mcf/d, and flow pressure rose from 1,500 psi to 6,000 psi [10.3 MPa to 41.4 MPa].
