To the Lawyers: Please translate this clause. Does this give the Oil and Gas Company the option to unitize the lease greater than 640 acres?
Lessee is hereby granted the right as to all or any part of the land described herein, without Lessor's joinder, at any time and from time to time, to combine, pool or unitize the land, royalty, or mineral interests covered by this lease, or any portion thereof, with any other land, lease or leases, royalty or mineral interests in or under any other tract or tracts of land in the vicinity thereof, whether owned by Lessee or some other person or corporation so as to create, by the combination of such lands and leases, one or more operating units, provided that no one operating unit shall, in the case of gas, including condensate, embrace more than six hundred forty (640) acres [except in the event of a horizontal oil or gas completion, in which event such unit may embrace as much as one thousand nine hundred twenty (1920) acres], and in the case of oil, including casinghead gas, (other than a horizontal oil or gas completion) embrace more than forty (40) acres; and provided further, however, that if any spacing or other rules and regulations of the State or Federal Commission, Agency, or regulatory body having or claiming jurisdiction has heretofore or shall at any time hereafter permit or prescribe a drilling or operating unit or spacing rule in the case of gas, including condensate greater than six hundred forty (640) acres, [or, in the case of a horizontal oil or gas completion, greater than one thousand nine hundred twenty (1920) acres], or in the case of oil or casinghead gas which is not a horizontal oil or gas completion, greater than forty (40) acres, then the unit or units herein contemplated may have, or may be redesigned so as to have, as the case may be, the same surface content as, but not more than the unit or the acreage in the spacing rule so permitted or prescribed. The term "horizontal completion" means an oil or gas well in which the horizontal component of the gross completion interval in the reservoir exceeds the vertical component thereof. However, it is further specifically understood and agreed, anything herein to the contrary notwithstanding, that the Lessee shall have the right to, and the benefit of an acreage tolerance of ten percent in excess of any drilling or operating unit authorized herein. The commencement of a well, or the completion of a well to production of either oil, gas, casinghead gas, condensate, or other minerals on any portion of an operating unit in which all or any part of the land described herein is embraced, or production of oil, gas, casinghead gas, condensate, or other minerals therefrom shall have the same effect under the terms of this lease as if a well were commenced, completed or producing oil, gas, casinghead gas, condensate, or other minerals in paying quantities on the land embraced by this lease. Lessee shall execute in writing and file for record in the records of the Parish in which the lands herein leased are located, an instrument identifying or describing the pooled acreage, or an instrument, supplemental thereto re-designating same, as the case may be. Any unit formed by Lessee hereunder may be created either prior to or during or after the drilling of the well, which is then or thereafter becomes the unit well. The failure of the leasehold title (in whole or in part) to any tract or interest therein included in a pooled unit shall not affect the validity of said unit as to the tracts or interests not subject to such failure. Either prior to the securing of production from any unit created under the authority hereinabove granted, or after cessation of production therefrom, Lessee shall have the right to dissolve the unit so created, without Lessor's joinder or further consent, by executing in writing and placing of record in the Parish or Parishes in which the lands making up such unit may be located, an instrument identifying and dissolving such unit. The provisions hereof shall be construed as a covenant running with the land and shall inure to the benefit of and be binding upon the parties hereto, their heirs, representatives, successors and assigns. In the event such operating unit or units is/are so created by Lessee, Lessor shall receive out of production or the proceeds from production from such operating unit or units or out of the shut-in royalty provided for above, subject to the provisions of Paragraph 8, such portion of the royalty specified herein as the number of acres (mineral acres) out of this lease placed in any such operating unit or units bears to the total number of acres included in such operating unit or units
