Royalties   Institutional   1992-93  Income   Program.    Minimum   capital
requirements  for the Partnership were met on December 10, 1992,  with  the
offering  of limited partnership interests concluding April 30,  1993.   At
the  conclusion  of  the  offering of limited  partnership  interests,  217
limited partners had purchased 5,418 units for $2,709,000.

The Partnership was formed to acquire royalty and net profits interests  in
producing  oil  and  gas properties, to produce and market  crude  oil  and
natural  gas  produced  from such properties, and  to  distribute  the  net
proceeds from operations to the limited and general partners.  Net revenues
from  producing  oil  and gas properties will not be  reinvested  in  other
revenue  producing  assets except to the extent that production  facilities
and wells are improved or reworked or where methods are employed to improve
or enable more efficient recovery of oil and gas reserves.

Increases   or   decreases   in  Partnership   revenues   and,   therefore,
distributions  to partners will depend primarily on changes in  the  prices
received  for  production,  changes in volumes of  production  sold,  lease
operating  expenses, enhanced recovery projects, offset drilling activities
pursuant  to farm-out arrangements, sales of properties, and the  depletion
of  wells.   Since  wells deplete over time, production  can  generally  be
expected to decline from year to year.

Well  operating costs and general and administrative costs usually decrease
with   production   declines;  however,  these  costs  may   not   decrease
proportionately.  Net income available for distribution to the partners  is
therefore expected to fluctuate in later years based on these factors.

Based   on  current  conditions,  management  anticipates  performing   few
workovers during 2001 to enhance production.  Additional workovers  may  be
performed  in  the  year 2003.  The partnership may  have  an  increase  in
production volumes for the year 2003, otherwise, the Partnership will  most
likely  experience  the historical production decline of approximately  12%
per year.

Oil and Gas Properties

Oil  and  gas  properties  are accounted for at cost  under  the  full-cost
method.  Under this method, all productive and nonproductive costs incurred
in  connection with the acquisition, exploration and development of oil and
gas  reserves  are capitalized.  Gain or loss on the sale of  oil  and  gas
properties  is not recognized unless significant oil and gas  reserves  are
involved.

The  Partnership's policy for depreciation, depletion and  amortization  of
oil  and  gas  properties is computed under the units  of  revenue  method.
Under the units of revenue method, depreciation, depletion and amortization
is  computed  on  the  basis of current gross revenues from  production  in
relation  to future gross revenues, based on current prices, from estimated
production of proved oil and gas reserves.

Should the net capitalized costs exceed the estimated present value of  oil
and gas reserves, discounted at 10%, such excess costs would be charged  to
current  expense.  As of March 31, 2001, the net capitalized costs did  not
exceed the estimated present value of oil and gas reserves.

Revenues

The  Partnership's income from net profits interests increased to  $118,440
from  $79,823 for the quarters ended March 31, 2001 and 2000, respectively,
an  increase of 48%.  The principal factors affecting the comparison of the
quarters ended March 31, 2001 and 2000 are as follows:

1.  The  average  price  for a barrel of oil received  by  the  Partnership
    decreased  during the quarter ended March 31, 2001 as compared  to  the
    quarter ended March 31, 2000 by 2%, or $.50 per barrel, resulting in  a
    decrease  of  approximately $800 in income from net profits  interests.
    Oil sales represented 21% of total oil and gas sales during the quarter
    ended March 31, 2001 and 37% during quarter ended March 31, 2000.

    The  average  price  for  an  mcf of gas received  by  the  Partnership
    increased  during the same period by 121%, or $3.62 per mcf,  resulting
    in  an  increase  of approximately $76,700 in income from  net  profits
    interests.

    The  net total increase in income from net profits interests due to the
    change  in prices received from oil and gas production is approximately
    $75,900.   The market price for oil and gas has been extremely volatile
    over  the  past  decade, and management expects  a  certain  amount  of
    volatility to continue in the foreseeable future.

<PAGE>
2.  Oil  production decreased approximately 230 barrels or 13%  during  the
    quarter ended March 31, 2001 as compared to the quarter ended March 31,
    2000,  resulting in a decrease of approximately $5,700 in  income  from
    net profits interests.

    Gas production decreased approximately 4,000 mcf or 16% during the same
    period, resulting in a decrease of approximately $12,000 in income from
    net profits interests.

    The  total  decrease in income from net profits interests  due  to  the
    change in production is approximately $17,700.

3.  Lease  operating  costs  and  production  taxes  were  49%  higher,  or
    approximately $19,700 more during the quarter ended March 31,  2001  as
    compared  to the quarter ended March 31, 2000.  The increase  in  lease
    operating expense is due to pulling expenses and maintenance on one non-
    operated  lease being performed in 2001 and the increase in  production
    taxes in relation to the increase in sales for 2001.

Costs and Expenses

Total costs and expenses increased to $23,122 from $22,416 for the quarters
ended  March  31,  2001 and 2000, respectively, an  increase  of  3%.   The
increase is the result of higher depletion expense, partially offset  by  a
decrease in general and administrative expense.

1.  General and administrative costs consists of independent accounting and
    engineering  fees,  computer services, postage,  and  Managing  General
    Partner personnel costs.  General and administrative costs decreased 3%
    or  approximately  $300  during the quarter ended  March  31,  2001  as
    compared to the quarter ended March 31, 2000.

2.  Depletion expense increased to $13,000 for the quarter ended March  31,
    2001  from  $12,000  for the same period in 2000.  This  represents  an
    increase  of  8%.  Depletion is calculated using the units  of  revenue
    method  of  amortization based on a percentage of current period  gross
    revenues  to  total future gross oil and gas revenues, as estimated  by
    the Partnership's independent petroleum consultants.

Liquidity and Capital Resources

The  primary source of cash is from operations, the receipt of income  from
interests in oil and gas properties.  The Partnership knows of no  material
change, nor does it anticipate any such change.

Cash flows provided by operating activities were approximately $125,100  in
the  quarter ended March 31, 2001 as compared to approximately  $66,200  in
the quarter ended March 31, 2000.  The primary source of the 2001 cash flow
from operating activities was profitable operations.

Cash  flows used in financing activities were $120,000 in the quarter ended
March  31, 2001 as compared to $60,000 in the quarter ended March 31, 2000.
The only use in financing activities was the distributions to partners.

Total  distributions during the quarter ended March 31, 2001 were  $120,000
of  which  $108,000 was distributed to the limited partners and $12,000  to
the general partners.  The per unit distribution to limited partners during
the quarter ended March 31, 2001 was $19.93. Total distributions during the
quarter  ended March 31, 2000 were $60,000 of which $54,000 was distributed
to  the limited partners and $6,000 to the general partners.  The per  unit
distribution  to limited partners during the quarter ended March  31,  2000
was $9.96.

The  primary source for the 2001 distributions of $120,000 was oil and  gas
operations  of  approximately  $125,100,  resulting  in  excess  cash   for
contingencies  or subsequent distributions to partners. The primary  source
for  the  2000  distributions of $60,000 was  oil  and  gas  operations  of
approximately $66,200.

Since  inception of the Partnership, cumulative monthly cash  distributions
of  $2,059,443  have  been made to the partners.  As  of  March  31,  2001,
$1,879,189 or $346.84 per limited partner unit has been distributed to  the
limited partners, representing a 69% return of the capital contributed.

As of March 31, 2001, the Partnership had approximately $148,600 in working
capital.   The  Managing  General Partner knows of no  unusual  contractual
commitments  and  believes  the  revenues  generated  from  operations  are
adequate to meet the needs of the Partnership.
