CONTINUOUS DEVELOPMENT;
RETAINED ACREAGE; AND DEPTH LIMITATIONS
Form 1. If Lessee is engaged in drilling operations on the lease premises at the end of the primary
term, this Lease shall not terminate if Lessee conducts a program of continuous drilli ng, allowing
no more than ____ days to elapse between the completion of one well and the commence ment of
operations for the next succeeding well. If Lessee is not actually drilling on the le ase premises at
the end of the primary term, but this Lease is maintained at the end of the primary term by some
other lease provision to continue to maintain the Lease in force and effect, then within _____
days after the expiration of the primary term, Lessee shall commence to conduc t a continuous
drilling program allowing no more than ____ days to elapse between the completion of one we ll
and the commencement of operations for the next succeeding well. For the purposes of this
continuous development provision, “commencement of operations” shall be presumed to be the
date Lessee commences actually drilling with rotary drilling tools of a suitable size necessary to
reach the objective depth. “Completion” shall be presumed to be the date of fili ng of a
completion or potential test report with the applicable governing agency, if a product ive well, or
the filing date of the plugging report with the applicable government agency, if a dry hole. If no
report is filed, it will be presumed the well was completed on the ______ day following the last
day of actual drilling. Once commenced, each well shall be completed by Lessee within ____
days from the date of commencement.
In conducting this continuous drilling program, if Lessee commences a well prior to the
time that it is otherwise required to do so, it shall be entitled to accumula te and later use any time
saved in the early commencement of a well, so that all or any part of the acc umulated time may
be used to extend the ____ day interval between the completion of one well and the
commencement of the next succeeding well. However, no more than ____ days may be
accumulated. If, during the drilling or reworking of any well, Lessee loses or junks the hole or
well or encounters any other mechanical or technical difficulties in drilling, a nd after diligent
effort, is unable to complete its operations, Lessee may preserve its rights under this Lease by
commencing, not later than ____ days after the date of the abandonment of the lost or j unked
well, the drilling of a substitute well at a location selected by Lessee on the tract on which the
lost or junked well was commenced but not completed, and completing the substitute well. In
that event the completion of the substitute well shall be deemed a completi on of the lost or
junked well in compliance with this continuous drilling obligation. On cessation of the
continuous development program, this Lease shall terminate as to all lands, save a nd except ____
acres around each producing oil well, and ____ acres around each producing or shut-in gas well.
The amount of acreage included in each producing or proration unit shall increase in the event
field rules formulated by the appropriate governmental authority requires producing or proration
units of a larger size. If at any time, after the expiration of the primary term or the conclusion of
the continuous drilling program, the applicable field rules are changed or the well or we lls are
reclassified as oil or gas wells so that less acreage is then allocated to a well or wells for
production purposes, this Lease shall terminate as to all acreage not then alloca ted to a well or
wells for production purposes after the change in field rules, or classification. Within ____ da ys
after a partial termination of this Lease, Lessee shall execute and delive r to Lessor a recordable
release of this Lease as to all lands, save and except the acreage allocated to each producing or
proration unit. After the primary term of this Lease, the acreage assigned to a produc ing well
shall be considered subject to a separate Lease for each well, with each Lease containing the
same terms and provisions of this Lease. Each separate Lease may be kept in force and effect
only by actual or constructive production or operations on the particular tract of land wit hout
regard to production or drilling operations on other tract or tract retained by Lessee, deem ed
subject to a separate lease or leases. Notwithstanding the termination of this Le ase as to a
portion of the lands, Lessee shall nevertheless continue to have the right of ingress and egress
from the lands still subject to this Lease for all purposes allowed under the terms of this Lease,
together with easements and rights of ways for roads, pipelines, and other facilities on, over, and
across all of the lands originally covered by this Lease, for access to and from the lands still
subject to this Lease, for the gathering of transportation of oil, gas, and other minerals produce d
from the retained lands. The sole liability or penalty for Lessee's failure to drill any well or wells
required or permitted by this Lease shall be the termination of Lessee's rights under t his Lease as
provided in this provision.
Form 2. If during the primary term of this Lease, a well is completed which is capable of
producing oil and/or gas in paying quantities, to maintain all of the lands under lease , Lessee
must develop the lease premises by drilling additional wells without a lapse of more than _____
days between the end of the primary term and the commencement of actual drill ing operations of
the next succeeding well. On the completion of a well at or after the primary t erm, which is
capable of producing in paying quantities, Lessee must develop the lease premises by drill ing
additional wells without a lapse of more than ____ days between the completion of one we ll and
the commencement of operations for the drilling of the next succeeding well. For the purpose s
of interpreting this provision, a well shall be deemed to be commenced when Lessee stakes the
location for a well. The completion date of a well shall be deemed the ea rliest of the following
dates: (i) the date on which the initial potential test is run; (ii) the dat e on which a dry hole is
plugged; (iii) a date _____ days after the date on which Lessee reaches total depth in the well; or,
(iv) the date certified by the applicable governing agency as the date a well has been completed
as a producing well. Once commenced, drilling operations on a well shall be conducte d with no
cessation of more than ____ days.
Upon cessation of this continuous development program, this Lease and all Lessee's
rights shall automatically terminate as to all lands covered by this Lease , save and except, as to
each well then capable of producing oil or gas in paying quantities, the producing or proration
unit surrounding the well, as established by the applicable governmental agency, and shall also
terminate as to all depths ____ feet below the total depth drilled in the well located on each unit,
or as to all depths below the base of the deepest producing formation in each well, whi chever is
greater. Within _____ days after a partial termination of this Lease, Lessee shal l execute and
deliver to Lessor a recordable release of this Lease as to all lands and dept hs, save and except the
acreage and depths allocated to each producing or proration unit. On cessation of the conti nuous
development program, any acreage assigned to a producing well shall be considered subject to a
separate Lease containing the same terms and provisions as this Lease. Each sepa rate lease may
be kept in force and effect only by actual or constructive production from or operations on t he
lands subject to that Lease, without regard to production or drilling operations on other lands
retained by Lessee under a separate lease or leases.
Form 3.
At the expiration of the primary term, this Lease shall terminate as to al l lands, save and
except the following:
a. For each well situated on the lease premises producing oil in paying quantities
and classified as an oil well and property spaced on the lease premises under the rules and
regulations of the applicable governing agency, the minimum acreage around each oil we ll
permitted under those rules and regulations from ____ feet above the top producing depth to
____ feet below the base of the deepest producing depth; or,
b. For each well producing gas in paying quantities or capable of producing gas in
paying quantities (with all shut-in gas royalty payments having been properly and time ly paid in
compliance with other terms of this Lease) and classified as a gas well, properly spaced on the
lease premises under the rules and regulations of the applicable governing agency, the m inimum
acreage around each gas well is permitted under those rules and regulations from ____ fe et
above the top of the shallowest producing depth and to ____ feet below the base of the deepest
producing depth.
Each tract of land around an oil or gas well, if practicable, shall be in a square or
rectangular shape, having a length no greater than twice its width. If a square or rec tangular
shape is not practicable, all acreage within a tract must be contiguous.
Within _____ days after the partial termination of this Lease, Lessee shall execut e and
file of record (and deliver Lessor an executed or certified copy) a recordable instrument
designating and describing all of the lands included within tracts surrounding commercially
productive oil or gas wells. Lessee shall also execute and deliver to Lessor a rele ase of all the
lands not included in the tracts surrounding commercially productive oil or gas wells. If Lessee
fails to execute and file of record this release or the instrument designating the lands surrounding
producing oil or gas wells, Lessor shall have the right to file such instruments which will have
the same force and effect as if executed and filed by Lessee.
Form 4. On the latter of (i) _____ days following the end of the primary term of this Lease, or (ii )
the conclusion of the “Continuous Development Program,” described below, this Lease shall
terminate as to all lands covered by this Lease not included within a “Wel l Tract.” A “Well
Tract” is defined as and shall consist of an area surrounding each well capable of produc ing oil
and/or gas not to exceed _____ acres for each oil well, plus a tolerance of 10%, or _____ acre s
for each gas well, plus a tolerance of 10%, with the Well Tract for each well being as nearly as
practicable in the shape of a square or rectangle surrounding each well. Should the government al
authority having jurisdiction prescribe the creation of a drilling, production, or proration unit
with a larger area than the area for a Well Tract, then the size of a W ell Tract shall substantially
conform in size with the drilling, production, or proration unit prescribed or permitted by
governmental regulations. If all or any portion of the lands covered by this Lease are pooled or
unitized under the provisions of the pooling clause of this Lease, the land that is poole d or
unitized shall be considered within the Well Tract of the pooled unit.
A “Continuous Development Program” shall consist of a period during which Lessee
conducts operations from the drilling of a well on the lease premises, or on land pooled with the
lease premises, with no lapse of more than ____ days between the completion or plugging and
abandonment of one well and the commencement of operations on the next succeeding well ,
with operations for drilling on each well being conducted with no cessation of more tha n ____
consecutive days. For purposes of this provision, completion of a well shall be deemed the da te
on which the applicable report on a producing well or dry hole is filed with the governmenta l
agency having jurisdiction. Commencement of operations shall be deemed to occur when a well
is staked.
Notwithstanding the termination of this Lease as to a portion of the lands, Lessee shal l
continue to have the right of ingress and egress from the lands still subject to this Le ase for all
purposes provided in this Lease, together with easements and rights of way for roads, pipelines
and other facilities on, over and across all the lands originally covered by this Lease , for access
to and from the lands still subject to this Lease, and for the gathering of transportati on of oil
and/or gas produced from the retained lands. This provision affects the secondary term of this
Lease, but it shall not alter the effect of any other provisions of this Lease whic h relate to lease
maintenance before or after the application of this provision, including, without limit ation, the
shut-in provisions, the savings clause, and the force majeure clause.
Form 5. After the expiration of the primary term of this Lease, to maintain it i n full force and
effect, Lessee must continuously develop all of the lands covered by this Lease without allowing
more than ____ days to elapse between the completion of one well and the commence ment of
actual drilling on the next succeeding well. The first continuous development well m ust be
commenced within ____ days after the end of the primary term of the Lease if a we ll was
completed as a producer or a dry hole within the primary term of the Lease, or within ____ days
after the completion of any well which is being drilled at the end of the primary term, whichever
is the later date. Completion of a producing well shall be deemed the date of t he potential test of
the well or the expiration of a period of ____ days after all good faith operations for drilling,
testing or completing the well have ceased, whichever is the earlier time. C ompletion of a dry
hole shall be the date when a well is plugged and abandoned, or the expiration of a pe riod of
____ days during which good faith operations for drilling, testing, or plugging and abandoning
the well have ceased, whichever is the earlier time. For the purposes of this provi sion, “actual
drilling” shall be the date on which Lessee stakes the location of a well. Aft er the end of the
primary term of this Lease, regardless of the number of wells which have been drilled and
whether any more wells can be drilled on the lease premises in any formation from which
production has been obtained, if Lessee fails to commence the actual of another well within the
required _____ day period, this Lease shall terminate as to all of the lands covere d by the Lease
except for the minimum amount of acreage necessary to be allocated to each producing well for
full allowable production under the then applicable rules and regulations (regardless of what
allocation Lessee shall actually have made to the well) and as to all de pths down to a depth of
100 feet below the total depth drilled in each producing well.
After the partial termination, the Lease on the lands held by a producing well shal l, for
the purposes of determining this Lease's maintenance by production or operations, be treate d as
if it were a separate lease from the Lease covering the lands allocable t o each other well so that
this Lease shall, as to each well, remain in force only so long as oil or gas i s produced from the
lands surrounding the well or the Lease is otherwise maintained in force and effect under some
other provision of this Lease as to each tract of land on which a well is located.
At any time after the Lease partially terminates under this continuous developm ent
provision, if the applicable rules of the governmental agency having jurisdiction over the le ase
premises are changed so that an additional well or wells can be drilled for producti on from the
formation from which a well is producing at the time of the partial terminati on on the acreage
which was held by a well at that time, Lessee shall commence the drill ing of an additional well
on any of the land then covered by this Lease (considering all of the land which is still covered
by this Lease as being subject to one lease, notwithstanding the fact it has be en treated as
separate leases by virtue of other parts of this provision) within ____ days after such rules and
regulations are changed, and shall continue to drill additional wells on lands covered by this
Lease (treating all lands being subject to one lease) without more than ____ days ela psing
between the completion of one well and the commencement of actual drilling on the next
succeeding well. Each well shall be drilled with due diligence and to a de pth sufficient to fully
test the formation from which the existing well is producing. Regardless of how many wells
have been drilled or whether or not any more wells can be drilled on the land, into tha t
formation, if Lessee fails to commence actual drilling of an additional well within _____ days
after the completion of a previous well, this Lease shall terminate as to al l lands except the lands
allocated to each then producing well under applicable regulations of the government al agency
having jurisdiction over the lease premises. Only the minimum amount of land to be a llocated to
a well for a full allowable under the then applicable rules and regulations shall be held by a well.
If a gas well is completed on this Lease and is ever reclassified as an oil well, or if a gas
well is completed and one or more oil wells is also drilled on land which is hel d by the gas well,
after the time for partial termination of this Lease, and the gas well then c eases to produce gas or
is reclassified as an oil well, Lessee shall, within _____ days after the gas well is reclassified as
an oil well or is plugged and abandoned, as the case may be, commence the act ual drilling of an
additional well on the lands formerly held by the gas well, continue to drill additiona l wells
without cessation of more than ____ days between the completion of one well and the
commencement of actual drilling of the next well, each of which well shall be drilled with due
diligence to a depth sufficient to fully test any formation from which oil is being produce d, or if
no oil is being produced, to the depth of the gas well or to the depth of actual production of oil or
gas in paying quantities. Regardless of how many wells have been drilled on the lands or
whether or not any other wells can be drilled into the objective formation under appli cable
regulations, if Lessee fails to commence actual drilling of an additional well within the _____
day period on the land formerly held by the gas well, this Lease shall terminate insofar as it
covers all lands previously held by the gas well except that which is then allocat ed to a
producing well (for either oil or gas), but shall remain in force as to all depths as to which it was
previously in force at the time when the gas well was plugged and abandoned or reclassifie d.
Only the minimum amount of acreage necessary to be allocated to a well for a full allowable
under then applicable field rules and regulations shall be held by a well.
In the event of a partial termination of this Lease, Lessee shall execute and deliver to
Lessor a partial release of this Lease as to all of the lands and depths which ha ve expired, under
this provision.
Form 6. At the end of ____ years after the primary term of this Lease, it shall terminate : (i) as to
all depths ___ feet below the stratigraphic equivalent of the deepest producing depth in any well
commenced on or before the expiration of the primary term on the lease premises or on any land
pooled with the lease premises; and, (ii) as to all of the lease premises outsi de
producing/proration units which are prescribed by the governing governmental agency.
