  • Fractures are made in the direction that is perpendicular to the least principle stress, after which fracking fluid is pumped into the space, which contains proppants such as frac sand, ceramic proppants, or resin-coated proppants, to aid in oil and gas extraction.[Neil Stegent] also referenced the difficulties and risks faced by E&P companies in terms of fracking and the lack of being able to control the direction and extent of fractures created in tight shale formations for the extraction of hydrocarbons.

    With Halliburton estimating that there are up to 5,000 wells with the potential for re-fracking in North America, the choice to do so could be more beneficial for oil and gas producers looking to rein in less lucrative projects."We can see re-fracks being the next upcoming thing to help us through this slump," he told delegates.As an alternative, more cost effective and less risky process, Stegent said that Halliburton was looking into refracturing old wells during the downturn in oil prices. To re-frac is to frac a well that has been previously fractured.

    "Re-fracking has been shown to be lower risk, and existing examples have d
