Abstract:
Petroleum production in Middle East countries in 1967 totaled 3,679,506,000 bbl at an average rate of 10,080,838 b/d. This compares with 3,407,666,000 bbl or 9,336,071 b/d in 1966. The principal production increases were in Iran, Kuwait, Saudi Arabia, Qatar offshore, Abu Dhabi, and Oman (first production).
New fields were found in offshore Iran, Neutral Zone, and Saudi Arabia.
There were no exploration activities in Iraq, Aden, Kamaran Islands, Yeman, Hadramaut, and Cyprus. The main areas of exploratory work were in Iran, Saudi Arabia, Neutral Zone, and the southern Gulf (both onshore and offshore).
INTRODUCTION
In Iraq, exploration remained at a standstill pending the resolution of a dispute about acreage holdings. Production decreased by 7.8%.
In onshore Iran, the IOEPC increased geophysical activity by a third, and completed 5 dry wildcats and 3 new-field discoveries. Production in Iran increased by 22% or more.
The Kuwait Oil Company, Ltd., completed one unsuccessful wildcat which had been started during 1967. The production rate was increased 0.74% to a new high of 2,292,380 bbl.
In the Neutral Zone, 12 development wells were completed successfully in the South Umm Gudair field. The Khafji offshore field production was raised by 8.7%. Two new-field wildcats were completed successfully in this Japanese concession. Neutral Zone total production was decreased by less than 1%, as a result of a 17% decrease in the onshore production.
In Saudi Arabia, Aramco found 3 new oil fields in the offshore area and one new gas field in the Rub'al Khali. Production was increased 8.6% and the company's ninth billion bbl of oil was produced.
The Bahrain Petroleum Company increased production 12½% to a new high of 25,370,055 bbl in 1967. Drilling was limited to 6 field-development wells.
In Qatar production rose about 12%, mainly from the Shell offshore Maydan Mahzam field.
Exploration in Abu Dhabi continued without success in both onshore and offshore areas. Production rose about 6% as the Zakum field was brought into production.
In the offshore area of Dubai the Fateh discovery was confirmed by 2 step-out wells. Seismic exploration was done both onshore and offshore.
In Sharjah 1 wildcat was lost due to weather, and the concession was terminated.
In Al Fujairah geologic and seismic work was done.
The first production from onshore Oman was attained in 1967. Geological and geophysical surveys were conducted both onshore and offshore.
Exploration in Turkey decreased appreciably, but crude production increased by a third. This is directly attributable to the availability of a pipeline from District V to the Mediterranean.
In Israel, exploration drilling and production of crude oil decreased; there was a large increase in development drilling.
Most locations of onshore concessions in the Middle East and of offshore concessions in the Gulf are shown in Figures 1 and 2 of the 1965 review.(FOOTNOTE 3)
Production of crude oil in the countries of the Middle East is summarized in Table I.

Arabian American Oil Co. (Aramco):
Five seismic parties were in operation in 1967 and a continuous wildcat program was maintained with as many as 3 simultaneous exploratory tests. Eight rigs were in operation for part or all of 1967 on wildcatting, development drilling, pressure-maintenance well needs, and workovers. A total of 8,628 km of seismic coverage was recorded in 57 crew-months. Eight wildcat and 39 development and injection wells were drilled in 4.76 rig-years of effort. In addition, major products were completed on facilities for handling the increased petroleum output.
Five land seismic parties using digital recording and computer processing were active in 4 of Aramco's 5 retained areas. Both refraction and reflection techniques were employed. One crew worked in the eastern Rub'al-Khali throughout the hot summer months while the other crew shut down for 3 months. Three parties working in the northern area were equipped with surface-energy sources whereas the 2 parties in the Rub'al-Khali used conventional refraction methods. The Dhahran TIAC digital computer center was improved during the year to handle the more sophisticated computer programs now in use.
The continuous wildcat program resulted in the completion of 8 tests with 2 drilling at year end. Four rigs worked a combined total of 1.57 rig-years on exploratory holes for a total of 90,192 ft drilled. An additional 5,383 ft of drilling was done on 5 water wells in support of the wildcat program. Three oil discoveries were made in the offshore area at Marjan, Karan, and Jana. Gas was found at Kidan in the Rub'al-Khali.

HADHRAMAUT
No activity was reported for the Hadhramaut or the Mahra Sultanate during 1967 and these areas are not known to be under concession.
ADEN--KAMARAN ISLANDS (now the PEOPLE'S REPUBLIC OF SOUTH YEMEN)
There was no exploration activity during 1967 within the Kamaran Island license area. The concession was terminated on November 29, 1967.
YEMEN
There were no developments during 1967, according to information received from John W. Mecom.
JORDAN
(Information supplied by HARRY WASSALL AND ASSOCIATES, INC.)
There were no concessions held during 1967. The only exploration activity reported during the year was conducted by the government Mineral Resources Authority (MRA). An exploration well projected to 5,000 ft had been spudded on Lisan peninsula in the Dead Sea area at the end of 1966, but no further information on the well has been released. A party of German geologists also was reported working for MRA in the Dead Sea area until about midyear. A contract seismic crew began a scheduled 1-year survey in October 1967. This work was to be done in the Lisan Peninsula, Hebron, Al Jaft, and Wadi Sirkan areas.
LEBANON
(Information supplied by HARRY WASSALL AND ASSOCIATES, INC.)
Exploration activity during 1967 was limited to continued drilling by R. F. Shaheen on the Batroun structure near Abrine. The wildcat was
Table XXII. OMAN--PETROLEUM DEVELOPMENT (OMAN), LTD., DRILLING ACTIVITY, 1967
End_Page 1563------------------------------
abandoned at a depth of 1,640 ft in January 1967, without having penetrated any prospective Lower Cretaceous or Upper Jurassic reservoirs.
The concessions held by 2 local companies, Petrolex and Becha Tabet, were cancelled in 1967. Both companies appealed this decision and the matter was still unresolved at year end. Similarly, the reinstatement of the Cie. Libanaise des Petroles (CLP) rights, to which the government has agreed, was still pending final action. CLP is negotiating for a joint enterprise with a foreign company and has tentative plans to retest the Yohmos 1 wildcat in southern Lebanon. A new wildcat is scheduled to be drilled near Qartaba.
SYRIA
(Information supplied by HARRY WASSALL AND ASSOCIATES, INC.)
Exploration and production operations continue to be reserved for the government and are conducted by the Syrian General Petroleum Authority (SGPA).
Four new rigs were imported in the spring of 1967, making a total of 8, all operated either by SGPA or by Russian contractors. Two rigs were purchased in the U.S., and 2 were imported from the USSR under terms of a drilling contract. Five rigs were operated by the Russians in the Souedie field in northeastern Syria, where 13 producers were completed. A total of 25 wells had been drilled in the field by the end of 1967. Five wells remain of the initial development program and are scheduled to be completed early in 1968. Development of the other fields in northeastern Syria-Karachok, Rumailan, and Darik-probably was in progress, but the only information available is that 1 well was completed at Rumailan.
No information has been received about exploration drilling scheduled for 1967 in the Sokhe area approximately 50 mi east-northeast of Palmyra.
It is believed that the SGPA continued to operate 1 seismic crew and 1 gravity crew throughout the year. The contract seismic crew active in 1966 completed its assignment at the end of that year.
The 400-mi pipeline from the northeastern fields to the Homs refinery and Tartus on the Mediterranean Sea was nearing completion at the end of 1967, and was to be commissioned in early 1968. Production was to begin at the rate of 20,000 b/d from the Souedie field, with the Karachok and Rumailan fields to be connected late in 1968. At that time production should reach 80,000-100,000 b/d, according to government spokesmen. Recoverable reserves are stated to be 150 million tons or approximately 1 billion bbl.
CYPRUS
(Information supplied by FOREST OIL CORP.)
Forest Cyprus Corp.:
This company has not resumed the operations discontinued at the end of 1963. The government has acknowledged that the force majeure clause in the concession contract was in effect from December 23, 1963.
TURKEY (Figs. 1, 2; Tables XXIII-XXVI)
(This section was prepared by MARVIN E. HAGEMEIER, Turkish Gulf Oil Co., whose assistance is gratefully acknowledged.)
All phases of exploration activity declined in 1967, about 40% below the 1966 figures. The critical factor of acreage held under exploration license at the year end was 8.7 million acres compared with 10.2 million acres at the end of 1966. Exploration and concession activities in 1967 are summarized in Table XXIII.
Development drilling increased substantially as the producing companies, principally Turkiye Petrolleri A.O. (TPAO), attempted to achieve maximum utilization of the Batman-Iskenderun pipeline. This TPAO-owned and operated line was inaugurated in late 1966 and replaced truck transport from the District V fields to the ATAS refinery. The line contributed greatly to a 34% increase in production-approximately 19.5 million bbl, or an average of 53,389 b/d.
Districts V and VI (Southeast Turkey basin):
With the exception of Mobil's Bulgurdag field in District III, all production and most of the exploratory activity are concentrated in this area.
Shell with 5 exploratory wells and TPAO with 10 were most active in exploration drilling. Independents completed 2 unsuccessful tests.
Shell's activity was concentrated on the Kayakoy-Beykan producing trend in District V and resulted in 1 discovery, the Kurkan South 1A. The discovery well is approximately 1.8 km southeast of the Kurkan field and 135 km north of West Kayakoy. After suspending the Kurkan South 1 at 6,350 ft, Shell reentered the hole, set a whipstock, and completed it as a discovery in

the Cretaceous Mardin at a new total depth of 6,370 ft.
Clark, Perkins, and Petropar relinquished a total of 7 licenses in District V and shut down their operations in Turkey.
In District V Gulf and Shell relinquished 1 license of a jointly held block of 5. Gulf's 50% interest in the remaining 4 licenses was transferred to Shell early in the year.
Mobil (80%) and Panoil (20%) surrendered 1 license containing the Selmo field and applied for a production lease on the field in November 1967. Mobil also applied for a production lease on the Silivanka field.
District VII (Adana basin):
TPAO completed 2 unsuccessful wells on the Gokdere structure just north of the Gulf of Iskenderun. The purpose of these wells was to evaluate Pliocene-Miocene gas shows found in Gokdere 1. Gokdere 4 was drilling at year end with the same objectives.
A CGG Flexotir crew conducted a reflection-seismic survey for TPAO on its offshore Gulf of Iskenderun licenses.
A block of 7 offshore licenses extending to the edge of the continental shelf was awarded to Turkish Gulf during the year. A seismic survey was planned for 1968 on these licenses.
The Continental-Elwerath-Panoil group added a fifth license outside the 6-mi limit to their offshore block in early 1967. Continental subsequently transferred its 43% interest in the block to Elwerath and Panoil and withdrew from Turkey. In late 1967 Elwerath and Panoil applied for the transfer of the former's 75% interest in the block to Panoil. This was approved early in 1968, leaving Panoil the sole rightholder of the licenses.
District I (Thrace basin):
TPAO was the only license holder in this district and confined their activity to seismic, gravity, and magnetic surveys. A Geographex "thumper" party used this technique for the first time in Turkey in this area.
District III (Sinop basin):
Gulf relinquished a block of 8 licenses in the Samsun area early in 1967, leaving TPAO as the sole license holder in the district. TPAO's first wildcat (Fasili 1) was drilling at year end near Sinop on the first of a 2-well program.
District III and IV (closed areas):
The greater

part of Districts III and IV is still closed to petroleum companies, including TPAO. Geologic and geophysical studies have been conducted by MTA (Maden Tetkik ve Arama Enstitusu), the Government Mineral Research and Exploration Institute. MTA spudded 2 wells of interest in 1967 (Fig. 2). The Hacilar 5 in District III is programmed for 4,000 m and is a follow-up to 4 structure holes on the feature. MTA is using a 15,000-ft capacity Russian rig on this test, and was drilling at approximately 3,000 m at year end.
The second well spudded in 1967 is the Katranli 3, near Tekman in District IV. A TPAO rig and crew are drilling on contract to MTA with a 2,400-m proposed depth.
Concentrated Russian drilling activity adjacent to the Turk/Soviet border has stimulated interest in this area, and at year end a second TPAO rig was rigging up on the Tuzluca 1. The well was spudded in January 1968.
DRILLING SUMMARIES
Exploratory and development drilling is summarized in Tables XXIV and XXV, respectively.
PRODUCTION
Crude production increased from an average of 39,703 b/d in 1966 to 53,389 b/d in 1967 (Table XXVI). Continued development by Shell on the Kayakoy-Beykan trend should raise its production in 1968. Panoil has reached agreement with TPAO for the purchase of its 20% share of Selmo production. TPAO mixes this lighter crude with its own heavy Bati Raman and Magrip oil, increasing

its pipeline transportability and probably permitting higher production rates from those fields. Throughput in the line totaled 12.5 million bbl in 1967, the first full year of operation, and 16.0 million bbl is predicted in 1968.
REFINERIES
Three refineries are presently in operation in Turkey. ATAS, located at Mersin on the Mediterranean coast, is owned jointly by Mobil (56%), Shell (27%), and BP (17%). Expansion which is essentially a "debottlenecking" process will increase the capacity of the plant from 65,000 b/d to 94,000 b/d. The IPRAS plant at Izmit is owned by TPAO (51%) and Caltex (49%). An application for a permit to expand this refinery from 44,000 b/d to 100,000 b/d was approved in February 1968. The third active refinery is the 15,000-b/d Batman installation owned by TPAO.
The permit for a fourth refinery to be built at Izmir by TPAO was granted in 1967. The plant will have a design capacity of 60,000 b/d and will be built with Russian assistance.
An application for a fifth refinery to be located on the Sea of Marmara was filed by Turk Petrol, a Turkish private company. Designed capacity will be 20,000 b/d, and the certificate was awarded early in 1968.

ISRAEL (Figures 3, 4; Tables XVII-XXX).
(Information supplied in part by G. GVIRTZMAN, Geological Survey, Oil Division, State of Israel.)
At year end, 12 different companies or groups held petroleum rights in Israel (Table XXVII, Fig. 3). The area covered by such rights is

thought to have decreased from approximately 3,225,713 acres at the end of 1966 to about 2,942,962 acres at the end of 1967. Asher Oil Company relinquished all of its rights in Israel, and a newcomer, Mayflower Oil Exploration Company, acquired rights in a joint enterprise with Israeli companies.
Total footage drilled in Israel during 1967 increased from 95,628 in 1966 to 98,048. The exploration drilling decreased substantially from 89,611 ft in 1966 to 66,449 ft in 1967. Development drilling increased abruptly from 6,017 ft in 1966 to 31,609 ft (Table XXVIII).
Of the 10 exploration wells drilled during the year (Table XXIX), 9 were abandoned without finding commercial production, and 1 was drilling at year end. Six of these wildcats were drilled on the coastal plain, 2 were in the Negev, and 1 in the Dead Sea valley. The Shoqeda and Bat-Yam exploratory wells were drilled for objectives in the Miocene of the coastal plain. The wildcat in the vicinity of the Dead Sea found traces of heavy oil.
Exploration activity, on the part of the concessionaires, in addition to drilling, totaled 17 party-months of seismic surveying, 11.5 party-months of gravity surveys, 5.25 party-months of ground magnetometer, 1.15 party-months of aeromagnetic surveys, and 6 party-months of field geology. The marine geophysical survey totaled 1 boat-month (sparker, gravimeter, and magnetometer).
Production of crude oil in 1967, from 32 wells in LIOP's Heletz-Brur-Kokhav field, is estimated to have totaled 974,000 bbl. Production was at an average rate of 2,706 b/d, a decrease of 27% from the year-end average of 3,700 b/d in 1966. Cumulative production totaled about 11,375,000 bbl.
Natural gas production in 1967 from 9 wells in NIPC's Zohar field totaled 3,899 MMcf. Production was at an average rate of 10,330 Mcf/d, an increase of 12% from the year-end average of 9,280 Mcf/d in 1966. Cumulative gas production totaled about 12,487 MMcf. The principal consumers of this gas are the Dead Sea Works, the Oron Phosphate Plant, and the industry of Dimona.
An Israeli company was reported to be producing approximately 90,000 b/d from the Belayim fields on the Sinai Peninsula at year end.
The aeromagnetic map of Israel, financed by the government, was published. Regional and stratigraphic studies carried out for the government by the Institute for Petroleum Research and Geophysics and by the Geological Survey of Israel progressed according to the 3-year master plan.
