Questions concerning spacing or correlative rights should be addressed to the Kentucky Division of Oil and Gas.
Short answer: Oil and gas are migratory in the same way as a wild animal ("mineral ferae naturae"); they do not necessarily respect property lines. Your neighbor owns all oil or gas produced from their well so long as it was drilled legally.
In Kentucky, the ownership of oil and gas is established by what is known as the "Law of Capture." which recognises the mineral ferae naturae of oil and gas. The ownership of oil and gas is actually an exclusive right to remove oil and gas or control their removal through the exercise of a deed or lease. The ownership of oil and gas is considered to be a severable right, a mineral interest with an agreed value that may be sold or traded separately from the ownership of the surface tract of land.
From: Coal-Bed Gas Development in the San Juan Basin: A Primer for the Lawyer and Landman by J. Hovey Kemp and Kurt M. Peterson:
"Water and oil, and still more strongly gas, may be classed by themselves, if the analogy be not too fanciful, as minerals ferae naturae. In common with animals, and unlike other minerals, they have a power and a tendency to escape without the volition of the owner .... They belong to the owner of the land and are part of it, so long as they are on or in it, and are subject to his control; but when they escape and go to other land, or come under another's control, the title to the former owner is gone. See Williams & Meyers, Oil and Gas Law ' 203.3 (1983 ed.)."
Oil and gas well spacing requirements established in KRS 353 were designed to protect the correlative rights of adjoining property owners, in particular see: KRS 353.510, KRS 353.610, 805 KAR 1:100 section 1-3, and 805 KAR 1:130. In the situation where: (1) you own the oil and gas mineral rights in fee simple, (2) a producing well exists on an adjoining property, and (3) that well complies with the spacing requirements of KRS 353 (or those in effect, if any, at the time it was drilled), the adjacent mineral owner or lessor owns all the oil or gas produced from their well. They captured it or "reduced the oil or gas to possession."
In the case of wells drilled for coalbed methane recovery, new statutes were adopted during the 2004 Legislative Session. The text of House Bill 577 is available on-line. In general, Section 15 of the act establishes 1,500 feet between wells and 750 feet to a (mineral) property line.
Provisions also exist to cover other cases.
