Ceneral Lrvel of Technology

Petroleum industry technology and equipment ln the USSR is basically similar to that developed in the US, but lags that of the west in all operations except perhaps in the transmission of crude oil and natural gas via extra large diameter pipelines. The areas of greatest US technical superiority lie in seismology and deep drilling, as well as, In the design and production of producing, processing, and pipeline installations.

A. Exploration methods in the USSR are similar to those developed in the US, but the Soviets are aboutears behind the US in applied seismograph techniques and the ability to nap deep drilling prospects. Soviet exploration for oil and gas utilizes all of the basic geophysical techniques, including seismograph, gravity meter andsurveys. Gravity and magnetic

accuracy ofordenravity meters is less than that of the US

type instrument. The Soviets have been unable to make reliable quarts

elements for their gravity meters and the difference in precision of readings is often critical. Gravity meters are essential for successful deep exploration

of the saltil deposits in the Caspian eabaymsnt.

The great contrast in Soviet nnd U3iph technology can be

attributed to the lack of modem computer hardware and software and the

obsolescence of receiving and recording equipment. The Soviets are deficient in the use and availability of magnetic tape and recording heads, digital and analog field recording equipment, computer playback centers for thef seicr.ic records, and hifih quality ^cophones and seisa-ic cable. The low

quality geophones and cable prevent the reception of low frequency signals reflected from deep lying structures. Soviet Geophones are reportedly under-damped and capable ofycles per second (CPS) signals; whereasPS are necessary for deeper exploration. The lack of computer gear precludes the display of variable density cross-sections and the ability tor integrate seiamograms. The widespread application of computers to seismograph operations has developed in the US sinceand since then it has revolutionized deep petroleum exploration.

Soviet seismologists rely heavily on the "refraction" method for regional mapping of basement structure, and the "reflection" method for the finalof drilling prospects. In the Vest, far greater reliance is placed on "reflection" shooting in all seismic work due to the greater accuracy of deep records vhich are vital to the iu&ppiiig of complex geological conditions. There is no evidence that the Soviets have developed weight dropping techniques like those used in the vest (Vibroseis or Dinoseis) in areas of high seismic noise background. Sparker nwthods are similar to those used in the west in offshore waters in order to avoid the detonation of explosives and fish kill.

B. Deep drilling 0 meter depths represent the major "bottleneck" in the future expansion of crude oil and natural gas production. Potential petroleum reserves are larg? but increasing well depths and rising well costs, vhich normally account for about IiOjS of total oil and gas industry investment, could limit output. Deepar drilling in old producing regions could also obviate the construction of long distance pipelines which consumef total industry investment and the costly development of new West Siberian deposits of oil and gas.

f all the oil and gas wells in the USSR are drilled

by tlie turbodrill method,6 by the rotary method, and the remainder by experimental techniques including the electrodrill and possibly percussion-rotary methods. Turbodrilling is exceptionally well suited for drilling in shallow (less0 meter deep) hard rock formations like those encountered in the development of the Urals-Volga Region, but it is inefficient in ths deeper soft rock formations found elsewhere. Rotary drilling is used> of the time ln the free world because it is much more efficient than turbodrilling0 meter depths.

Turbodrilling differs from rotary techniques in that drilling fluidsownhole motor (turbine) and bit, while the drill pips remains stationary. In rotary drilling, the entire drill column ond the bit arc rotated from the surface by motors. Slower rotational speeds, increased torque, asd reduced axial loads and wear on bits una drill pipe represent the chief economic advantages of the rotary method. Shortages of high quality drill pipe and tri-cone bits limit the use of rotary drilling0 meter depths ln the USSR. Ihe Soviets are also deficient in mud systems and in the technology of drilling fluid composition which adversely affects the penetration rates, Mt life and turbodrill life.

C. hose in the USSR are similar to those used in the west,

with one major exception. While developing the vast Urals-Volga oilfields in

tbe post World War II period, the Soviets Introduced the practice of

water flooding new fields at the outset or primary reservoir drive mechanism has

been exhausted ond co-xx?nces at the start of the secondary recovery phase of

the production cycle. The widespread use of water floods to maintain

reservoir pressures theoretically serves to increase ultimate reserves and

recovery, and requires tha drillingever number of high yield flowing

wells. In practice, the Soviets ruin fields by uneven flooding when they

overproduce flush wells In order to ne^evcT'p^oduction goals. When poanlble,


natural gas reservoirs are repressured by recycling dry processed gas back into the producing strata with compressors, similar to US field procedure.

The area of greatest technical deficiency in production methods is the Soviets highly automated field equipment, high pressure well head units, centrifugal down hole pumps, and to produce two or more overlying reservoirs simultaneously, without the drilling of extra wells. The lack of equipment for processing condensate and associated gas at oil wells and the lack of sulphur


'removal installations are matters of increasing concern to Soviet production


'operations. Much of these by-products are currently wasted. Aboutillion cubic meters of associated gas was flared Oil and gas well cemsnting techniques are also inadequate and improvement would reduce the amount of water contamination in producing zones.

P, Offshore technology ir. the USSK ia far behind that developed in the US, and in use throughout most of the waters of the free world. Petroleum deposits located offshore in the Caspian Sea in water depths exceeding h0 meters have been inaccessible, except by directional drilling from either onshore locations, or by drilling from manmade offshore islands which are connected to the mainland by trestle supported roadways. The Soviets have very limited experience with floating jack-up type, drilling platforms. he "Apsheron" was the Soviets only offshore floating platform and it was limited to the drilling of shallow wells no more0 meters deep in up toeter water depths. Inhe Sovietsodem offshore deep drilling platform, theostillion from the Netherlands. The Khazar should ae. able to0 meter wells in water depths ofeters. However, maintenance of the Khazar equipment my prove


difficult and prevent optimal performance. The Soviets haveeed forffshore platforms in the Caspian Sea, but only one, the "Aierbaidjan"nder construction at Baku, lhe import of additional platforms from western suppliers appears likely. The Khaxar accounted for aboutf total petroleum Industry equipment imports The US industry possesses hundreds of offshore drilling platforms which operate throughout the world and hold most operating records. In addition the US industry has pioneered and developed most of the intricate offshore support systems and related technology which permit the economic exploitation pipelining, and storage of offshore crude oil and natural gas.

E- Ihc pipeline transmission of crude oil and natural gas through extra large diameter pipelines over great distances has reached its highest pointelop=en* ir. the USSR. The Soviets aie cui-iently laying oil and gas pipelines *i3 andnches in diameter which arc0 kiloT(;tcrs lone; whereas, the largest llnopipe used in the US is2 inches in diameter for relatively short distances. This experlnce has posed several Interrelated technological problems. In construction equipment, ln llnepip? metallurgy and fabrication, in the design of pumping and compressor equipment.

Petroleum industry equipment of all typhis is in short supply in the USSR,

and quite often it is obsolete, or unreliable. The short supply and limited performance of bisic oilfieldingcs on all phases of industry operations. In many instances, moderniiuition of equipment could be achieved by further modification of existing types; hovever, in other instances the equipment needed may not be domestically produced, and has to be Imported. Importa of petroleum industry equipment almost doubled5eflecting greatly increased purchases of drilling equipment.

equipment requirements include magnetic tape andcomputer hardware and software processing seismic records,equipment, and gravity meters. Seismic field operations wouldimproved with the acquisition of digital and analog recordingrelated software) and improved geophones and seismic cable.

In the future, moresophisticated producing equipment which can operate in arctic and permafrost

conditions will be essential for development of the W. Siberian oil and gas deposits (special wellheads, pumps and valves gathering systems and tank batteries).

Data on Soviet Hydrocracking

With tlie extensive demand for residual fuel oil in the USSR, there has been no widespread development of further processing heavy residuals, thus obviating the need for extensive introduction of catalytic cracking and hydrocracking of distillate fuel feedstocks. 7 it was*planned to develop the technology of hydrocracking in the USSR to yield |low sulfur diosel fuel and jet fuel, not to maximise gasoline output as in. tage system was being developed at-the rcaearch level, but problems were experienced in the developmenttable, efficient catalyst.
