Kara Sea could become one of the major petroleum regions in the USSR early in the next century. We estimate that recoverable oil resources in Ihe Kara Sea amount toillion barrels, roughly double (he provedat Alalia's Prudboe Bay. If developed, these resources could in principle support productionillion barrels per day) -about one-sixth of cuircnl Sovietnearlyears. Of tbe remaining oil frontiers in the USSR, only the Barents Sea and perhaps the Caspian region appear to have higher potential

oil production in established areas falls and new onshore oil becomes more difficult and expensive to find, tbe Kara Sea could play an increasingly important role in Moscow's; oillthough the adjacent Barents Sea will clearly remain tbc primary site of Soviet attempts to Up Ihc oil potential of the Arctic continental shelf, we believe Ihe Kara Sea will be neat on the Soviet agenda. Lagging activity in theby five toears. Given the environmental harshness of the Kara Sea and limited eiploralion activity thus far. we sec little likelihood that this area willignificant source of oil until around the lum of the century.

Many factors indicate that development of Kara Sea resources willlow and difficult process This region is one of the most severe and remote environments ever considered for drilling, and the Soviets will have to overcome serious financial, technological, and logistic problems to bave any chance of success Drilling activities in lhc Kara will be more ei pensive than in any currently producing petroleum region in the USSR and could exceed the coats of US and Canadian operations in the Beaufort Sea. The Soviets will need to acquire Western rigs specially designed io withstand ice forces and temperature stress and will hare loupport infrastructure mote efficient than any they have assembled to date- Down the road, produclion activities will be inhibited by high cosl and by distance from major ports and pipelines

The circumstances thai male the Karaoreboding exploration area to the Soviets also make it an excellent candidate for joint ventures with Western firms. US and Canadian oil companies have been operating in the Beaufortarea environmentally analogous to the Karamore thanears and are world leaders in drilling and production in ice-covered waters. Although ihe competitive position of Scandinavian and

Weil European companies is escellenl for join" venture* in lesinonethelessarea* such as ihe Barenli Sea. Northfirm* could be lhc major competitors for Kara Sea joint venture* if the Soviets open the area for Western cooperation. From the securitythe area is not nearly as militarized as the Barents and is so remote that the preaence of Westerners would pose little threat lo Soviet culture or national interests Nevertheless. Moscow will be forced to weigh iu naval securify concerns against iu economic need to develop potential Kara Sea oil resources.

Kara and Barents development could mean billions of dollars ia trade between the USSR and the West over the next several decade* Evert if the Soviels decide to go itno >oiBt ventures and no Wesiernwould still have to spend enormous amounts erauiprnent. control systems, and consulting services. Any effort to restrict such purchases for the Kara Sea would reinforce ihe Soviet'sear lag behind tha Weal in Arctic offshore expertise. Rather, we believe Moscow may consider some form of joint venture arrangement to speed up (he replenishment of its reserve base with Arctic discoveries before the turn of the century. Increased trade would live Moscow more political clout, esrx aatry if Soviet Arctic cVeveSopmentarge share of the worldwide oil services and equipment business targeted to harshJoint ventures, in particular, would give Moscow some importani new economic leverage as Western companies sought lo protect their equity investment in Soviei oil prospects

South Kara

Two source rock units are present in ihe Soulh Kara. Our analysis suggests ibai mosi of tbe Upper Jurassic source rocks underwent an appropriate geochemical history. This source reck probably has characteristic* very similar to related onshore source rocks that are believed lo produce most of Ihe Oil in Ihe prolific Wesl Siberian Basin, In addition, the Crelaceous-age source rocks in the West Siberian Basin are believed to extend offshore Into the South Kara. They are rich in organic carbon, but the types of organic carbon arc not as ptone to produce oil as those in the Jurassic. Moreover.

Therefore, like Ihe Creiaceous source rock* In ihe North Kara, these rocks are likely to contribute significam Quantities of biogenic gas rather lhan thermally generaied

The transformation of buried or tart ic mailer into hydrocarbons is at the core of our analysis. This process is extremely complex, but in virgin area* such as the Kara Sea. we believe analysis of the generation process is the roost reliable methodology for making resource assessments. Although technical data on Specific structures and rock strata are limited, enough geological information exitis to make reasonableof geochemical factors and to eslimate past geoenvironment!

Once organic mailer is deposited and buried, two factors afTcct lhc Iran*formation into hydrocarbons: temperature and llnv

This process yields hsdrocarbons. simpler molecules eon-laining only hydrogen and carbon, as well as several byproduct, such as sulfurous gases. Our analysis estimated the temperature of the source rocks on ihe basis of the depth of tbe rocks and temperature profile* In Ibelr vicinity. Depth of the rocks was delcrmined from limited geological information fiom several locations In the Kara Sea. Tbe tempera lure profiles were based on beat-how measuremenis at Ihe same sites


ufficient temperature is reached, organic hydrocarbons begin forming, but ibe process does not occur instanUneously.eneral rule, high tern-peralureshort time have an effect similar lo low temperaturesong lime. In either case, an enormous length of lime is involved in successfully forming any significant quantity of hydrocarbons. Depending on ihe tcmpcralure and Ibc type of organic material, ibe required lime can range from millions of year* lo hundreds of millions of years. For example, some of the most significant source rocks of the world-In West Siberia, tbe Middle East, the Norih Sea, the Gulf of Mexico-are of Jurassic age,illion years old

Time iscriiical after hydrocarbon* arc formed. If ihe generated hydrocarbons are not expelled from the source rock imo surrounding rock layers, the heat will continue lo crack ihe molecules until only gas and carbon residue remain. Therefore given the tempera-lure of the sourcearrow range of time exposures exists for ihe optimal formation of each particular type of hydrocarbon (oil. condensaic, gas).
