A method of propagating a fracture farther from a well-bore into an oil and/or
gas-bearing zone of a target formation while inhibiting growth of the fracture
into an adjacent water-bearing zone under or over the oil and/or gas-bearing zone,
comprises creating a zone of increased in-situ stress a vertical distance adjacent
a target interval and then creating a main fracture in the target interval by,
for example, fracturing the target interval with enough fracture fluid and pressure
to propagate the main fracture, inter alia, vertically to the zone of increased
in-situ stress. When vertical growth of the main fracture reaches the limit set
by the zone of increased stress, additional fracture fluid pumped into the target
interval tends not to propagate the main fracture vertically beyond that limit
and, instead, tends to propagate the main fracture more laterally and farther from
the well. Such zone(s) of increased in-situ stress can be created above, below,
or both above and below the target interval.
