"Times New Roman";color:#222222">Production from unconventional plays has come up as the major source of hydrocarbon production in North America in the past decade. The
most efficient method of producing from very-low permeability reservoirs is through horizontal wells with multiple hydraulic fractures. To extract most amount of hydrocarbons from an acreage, it has become common practice to space multiple horizontal wells
very close to each other. This often results in frac-hits- a phenomena where production from an existing well is considerably decreased. To extract the most hydrocarbons, it is common practice to refracture already stimulated wells. If successful, this can
result in increased production.</span><span style="font-family:"Times New Roman",serif;
