Wildcat wells were plugged in the not-yetproductive Raton, Hagan, and Albuquerque Basinsof northeastNew Mexicoand in Luna County of southwest New Mexico. Wildcat wells drilled in the TucumcariBasinof northeast New Mexico encounteredencouraging amounts of hydrocarbongas. Almost 12,000,000ft of hole were drilled in New Mexico in1982, making it the second best year in history and surpassedonly by the record 74,076,000 ft drilled in 1981.The averagedepth of wells drilled in 1982is 5,188 ft, 278 ft more than the average depth of wells drilled in 1981. Fig. 1 showsthe locationsof the significant wildcat wells drilled in New Mexico in 7982; table 1 summarizes the significant wildcat discoveriesand table 2 summarizesthe significant wildcat dry holes. For purposes of this report, a significantwildcat discoveryis defined as a well in which commercial amounts of oil or gas from a formation have been discoveredat a distanceof more than 5 mi from the limits of previously discovered fields with commercialproduction from that formation. A significant wildcat dry hole is defined as a well drilled in an unproductive basin or part of a basin that encounteredan encouragingshow of hydrocarbonsbefore being abandoned.Table3 lists wildcats which were being drilled at the end of 1982 and which were locatedin unproductive basins. SoutheastNew Mexico Drilling activity has been high in three of the four geologicsubdivisionsof the Permian gc,tt* Basin in southeastNew Mexico: The Dela" ware Basin,the Central Basinplatform, and 36) the Northwest shelf.The Rooseveltuplift has seenonly a moderateamount of drilling. The PermianBasinyielded severalsignificantoil and gas discoveriesin 1982(fig. 1; table 1).

Slill further north, the Flag-RedfernOil Company No. 1 State'17' (fig. 1, no. 2; table t, no. 2j found gas at a depth of 826 ft in the San Andres Limestoneand is the first San Andres discovery in De BacaCounty. The main targets o{ development drilling on the Northriest shelf are the "tight" gas sands of the Abo Formation (Permian).Abo production is presently limited to north-centralChaves County but severalwildcats drilled in 19g1 '1,982 and have encountered promising gas shows from the Abo in Lincoln and DJBIca Countiesand evenasfar north asGuadalupe County.The Abo play hasbeen discussedby Wheatley(1981),Broadhead(1982b),and Scoit (1982).Other developmentdrilling on the Northwestshelf is mostly for oil iri the San AndresLimestoneand the Queenand Cravburg Formations(Permian). Very few wells were drilled on the Roosevelt uplift in 1982.Chief drilling targetsare Pennsylvanianand Mississippianroiks. 39 calculated open flow of 36,972 thousand ft3 ol gas per day TMCFGPD) from the Morrow Series (Penn,sylvanian).Major targets of development drilling in the D'elawaie Basin in 1982 were gas in the Morrow, Atoka, and Strawn Series (Pennsylvanian) and oil in the Bone Spring Limestone and pennsylvanian 5vstem. -The Central Basin platform of southeastern Lea County also saw a high level of drilling activity in 1982,but only one significant wildcat discovery was made, gas fiom the Seven Rivers Formation (permiari) by the MGF Oil,Company No. 1 J. Wright (fig.'t, no.20; table l. no. 20). Developme-ntdriiiing of shallow oll reservoirsin the Yates,Seven Rivers. Qugel, and Crayburg Formations (permian) and the San Andrei Limestone ipermiani predominates on the Central Basin platform. Severalfields produce oil with the aid of watertlood operations. The Northwest shelf of the permian Basin was the most actively drilled area in south- Northwest New Mexico The San Juan Basin of northwest New Mexicohas seena high level of drilling activity in 1982,even though the number of wells drilled was down approximately50% from 1981.As in past years,most of th; drilling has been for gasand concentratedin San Juan and western Rio Arriba Counties. Few wildcats were drilled, but development activity was heavy. _Majordevelopmentobjectives for gas in the San Juan Basin are ihe Dakota Sandstone (Cretaceous)and sands t o n e so f t h e M e s a v e r d eG r o u p ( C r e t a ceous),including the Chacraand pictured Cliffs sandstones.The Gallup Sandstone (Cretaceous)is a maior obiectivefor development drilling of oil wells.

The lone significant wildcat discovery drilled in the San|uan Basinin 1982was the Lewis Energy No. 1 Lewis 4-20-2, located in northern SandovalCounty (fig. l, no. 26; table 1, no. 26). The Lewis well was completed in the Mancos Shale(Cretaceous)for an initial production of 120 BOPD and 180 BWPD over an open-holeinterval of 806 ft. Northeast New Mexico Two extremely important wildcats were drilled in the TucumcariBasin in 1982.The Trans-PecosResourcesNo. 1 Latigo Ranch Blk A' (fig. l, no. 25; table 1, no. 25) found potentially commercialquantities of hydrocarbon gas. Although final reports indicate a gasflow of only 275MCFGPDthrough perforations from 5,658to 6,764ft, the well reportedly flowed as much as 3,000MCFGPD during-difficult completion operations.The Trans-Pecoswell is an extremelyimportant d i s c o v e r yb e c a u s ei t s u g g e s t st h a t l a r g e amounts of gas, and possibly oil, may be presentin the nonproductiveTucumcariBaResourcesNo. 2 Latigo sin. The Trans-Pecos Ranch (fig. 1, no. 38; table 3, no. 38) was spudded late in 1982, and is scheduled to drill to 7,250ftto test the PennsylvanianSystem. AIso in Guadalupe County, a gas discovery was reported in the Abo Formation (Permian) by the O. H. Berry No. 1 TucumcariFNB (fig. l, no. 24; table 1, no. 24). Although the small initial potential of 88 MCFGPD and 120 BWPD makes the economic viability of the Berry well extremely doubtful, it does indicate that the Abo tight gas play may extend as far north as central Guadalupe County, although probably not as a single continuous field. In the southeasternpart of the TucumcariBasinin Quay County,the DesanaCorporationNo. I Wichita (fig. t, no. 39; table 3, no. 39) was spud in late 1982,and will drill to 7,350ft to test the PennsylvanianSystem.

On the Bravo dome of Union, Harding, and Quay Counties, development drilling for carbon dioxide in the Tubb sandstone (Permian) continues. Onlv about 10 wells were drilled in searchof cirbon dioxide in L982, down sharplv from 140wells drilled in 1981.

Completion of a pipeline to tranlport the carbon dioxide to the PermianBasin is scheduledfor the near future. The pipeline will enableoPeratorsto produce and sell carbon dioxide from the currently shut-in Bravodome wells. The carbon dioxide will be used in enhanced-oilrecovervooerationsin the Permian Basin. In the AlbuquerqueBasin, Shell Oil Company plugged its eighth well in 1982.The ShellNo. 1-24West MesaFederal(fig. 1, no. 28; table 2, no. 28) flared gas and was reported to have intermittently flowed large quantities of gas during drilling. The gas probablycamefrom either Cretaceousor Teriiary rocksand confirms the shows reported by previously drilled Shell wells in the AlbuquerqueBasin.Shellcontinued its leasing programafterabandoningthe WestMesawell. Black (1982)discussedthe petroleum potential of Cretaceousrocks in the Albuquerque Basin. Elsewherein northeastNew Mexico,SolvEx Corporation announcedplans to build a plant that will extractoil from the SantaRosa tar sands (Triassic)in central Guadalupe County. Solv-Ex received approval of $20 million in loan guaranteesfrom the federally funded SyntheticFuels Corporation to help build the plant. The geology of the Santa Rosatar sands has been discussedby Gor- stw at 810 ft. man and Robeck (1946) andBudding (1979' 1980). Although no significant wells were completedin the RatonBasinin 1982,petroleum potentialis present.Wellsdrilled in pastyears haveencounteredencouraginghydrocarbon shows (Speer,1976;Broadhead,1982a). Severalwells were drilled to follow up on the 1981recovery of oil in the Hagan Basin by the PeltoOil No. 1 Ortiz (Broadhead,L982a) birt without success.The John Gianardi No. I CKZ (fig. 1, no. 37; table 3, no. 37) was spudded in late 1982, and is scheduled to drill to 7,000 ft.

Wengerd (1959)and Foster (1964)discussed the petroleum potential of areas adjacent to the Cities Service well. Although no production currently is taking place in southwest New Mexico, potential is present (Foster and Crant, ld74: Greenwood and others, 1927; Thompson, 198.1;Thompson and Jacka, 1981); several wells drilled in past years encountered promising sh9_ws of both oil and gas (Thompson and Bieberman, 1975;Thomnion and others, 1978; Thompson, 1982;. Effect of discoveries on oil and gas production New Mexico's oil and gas production and reserveshave been decliningln recent vears. but the state continues to 6e a maioi orol ducer of both crude oil and natural gas. In 1981, New Mexico was the seventh iareest producer of crude oil and the fourth larEest producer of natural gas in the United StXtes (New Mexico Energy and Minerals Department, 1982, p. l3). production of crude oil in New Mexico in 1981 was 66.90 million bbls. a 4.4Vodecline from 69.90 million bbls pro_ duced in 1980.Total gas production *u, i.l2 trillion ft, down I.In irom 1.13 trillion ft, in 1980.

Data obtained from the New Mexico Oil Conservation Division indicate that the decline in oil production decreased to about 2Vo in 798), but that sas production declined by at least l\c" in p:g2.

The gas-production decline was caused mostly by. a decreased demand for gas and not by a decreasedcapability to produce eas. Steepli declining production from the Elrrpire-Abo oil field in southeast New Mexico is the largest .reasonfor the decline in the state,s oil production; production in the Empire-Abo field dropped from 9 million bbls in 1980 to 5.2 million bbls in 1981 (New Mexico Energy a n d _ M i n e r a l sD e p a r t m e n t , 1 9 8 2 ,p . l 8 ) . d i l production from all other fields in the state increased by 739 thousand bbls in 1981. In 1981, the Permian Basin of southeast New Mexico produced 93% of the state,s oil and 50Voof the state's gas; the San Juan Basin of northwest New Mexico produced 7Vaof the state's oil and 50% of the state,s gas (New Mexico Energy and Minerals Defartment, 1982,p- 19).As of January 1981,New Mexico had reserves of 929 miliion bbls of oil and 1 7 . 3t r i l l i o n f t ' o f g a s ( N e w M e x i c o E n e r s v and.

First, the new fields will be developed and the oil and gas obtained from them will qeplacewaning production from older fields. Second, the discovery of the new fields will encourage the drilling of more wildcats, to the subsequent discovery of more !9a.d.ing fields. The present decline of oil production in New Mexico will be lessenedor stopped not only by the new oil found bv the wildcat discoveries but also by the ex[ensive development drilling and by enhanced-recovery programs in the Permian Basin. Also the Bone Spring oil discoveries in Lea and Eddv Counties indicate that a large amount of oil is yet to be found in the Bone Spring Limestone. The Devonian, Pennsylvanian, and Permian Systemsall yielded significant oil discoveries in 7982. The future of gas production in Ner.r'Mexico is promising, provided that a market is created for the gas. The Morrow Series in the Delaware Basin was a major producer of natural gas in the 1950's and'1.970's;wildcat discoveriesand extensive development drilling '1982 rn indicate that the Morrow will contribute significantly to gas production in coming years. The 'tight'Abo gas sands of Chaves County and Cretaceous sandstones in the San fuan Basin will also contribute significantly to future gas production. For the more distant future, good promise to replace depleted reserves of the Permian and San Juan Basins exists in the not-yetproductive frontier areas:the Tucumcari, Albuquerque, Hagan, and Raton Basins of northeast New Mexico and the Pedregosa Basin, Acoma Basin, and adjacent parls of southwest New Mexico. All of these basins have the_potential to be hydrocarbon producers. Peak development of any of these basins that proves to-be productive may not occur for several decades.
