Printed in the U.S.A. © 1996 by Western Atlas International, Inc. , C on rotulot1ons to all of you on a job well done in 1995. Your hard work, commitment to excellence, and dedication to Western continue to inspire me Messag and make me proud to be port of the Western fami ly While such fine accom­ plishments encourage us to move forward to meet whatever tasks the year 1996 will hold, we must now take what we have learned from the previous year's experiences and use these successful efforts to define our miss ion for the coming year - GROWTH . As we have learned in the past, growth involves change and risk. Thanks to the resourcefulness and talents of Western employees, we, as a company, are able to take the steps necessary for growth. In order lo better address our clients' needs in th is changing seismic industry, Westerners have the ability to toke risks and to meet whatever challenges that arise. In retrospect, Henry Salvatori solicited help fro m two buddies, built a recording truck in six weeks, and founded a geophysical company in the mid­ dle of the Great Depression Booth Strange in 1955 devised a way to process 24 seismic channels simultaneously, wh ile the res t of the industry processed each channel independently. In the 1960s, Western [spearheaded in part by Carl Savit) was among the first to recognize the necessity of con­ verting seismic signals from analog to digita l. Western was able to take that step at o time when other firms were unwilling (perhaps due to a lack of vision) or unable (perhaps due to insufficient resources) to ta ke such a leap. On the whole, the transform ing forces and resulting major advances hove involved toking risks, stepping out in to unproved te rritory, doing what we believed was necessary for our clients' and Western's success During the pas! year, we have doubled our compu ti ng capacity and expanded our data processing capabilities info seven new cen ter locations . We implemented advanced land and transition-zone acquisition technologies in new geographic areas, expanding operations in four countries and com­ mencing startup operations in eight countries . On the Health/Safety/Environment fron t, one sta tistic stands ou t above all others- zero fatalities for Western Geophysical in 1995 1 This remarkable achievement was attained with over 52 million company-wide exposure hou rs Newly released and soon-to-be released improvements in marine streamer technology, coupled with ongoing vessel upgrades, will sign ificantly increase capability and asset utilization of ou r existing seismic fleet The industry's largest sing le speculative data project, the MEGA Survey, is expected to be complete in early 1996 (two and a half years ahead of schedu le) This ocean-bottom cable survey has set new standards for 3-D quality and seism ic data resolution. We continue to lead the seismic industry in our commitment to develop new, innovative seismic and processing technology through new software applications and long-term research and development efforts Our advances in applied technology continue to result in quantifiable benefits for clients in terms of product quality and efficient se rvice. Nol all companies hove the strength to change and take risks Our prede­ cessors and our cu rrent team have built a company that is confident enough to have a vis ion and is strong enough to accomplish it. This is Western's tradi­ tion and ourfuture.

With its lush , green mountaintops straddling acro ss the equator and rising from the bril liant blue waters of the Pacific and Indian Oceans, Indonesia is the world's largest archipelago. From east to west, it is spread across an area sim ilar in distance to the stretch between New York and San Fran­ cisco. Colonized by the Dutch and proclaiming its independence in 1945, th is island coun tr y is cul tural ly, ethnically, and racially diverse. Visitors stop on the island of Ja va to rel ive the most catastrophic volcanic eruption in world history - Krakatoa. In contrast, other vis it ors stop by the is land of Bali to enjoy the qu iet waters, sun-drenched beaches, and palms. "Bahasa In donesia," th e national language, is but one of a great many tongues spo­ ken by the country's inhabitants. Party 314, operating under the name of Western Geophysical' s associ­ ate in Indonesia, P.T. Artho Drill, is under long-term contract on a large onshore block situated in the cen tral part of the island of Sumatra, consi st­ ing of mostly low lying coastal swamp in the eastern portion extending inland to generally higher ground in th e west. Several large rivers cross the block, flowing int o the Straits of Malacca. This area is sti ll partially covered with dense tro pical primary jungle, though in recent years a significant por­ tion of the forest has been fel led for developments such as palm and ru b­ ber planta tions .

Operating at full capacit y to prepare for required back-to-back 3-D recording operations, the survey crew is headed by Soerono SK and supported by senior staff surveyors Edyson, Mohammad Maswan, Partomuan Harahap, Bersama Situmorang, and Rustam Effendy. As the maiorit y of the work area stil l has a dense foliage cover, conventional survey methods are re quired once a primary control grid has been es tablished from specifically locoted GPS points In addition, as many as 60 line-cutting and bridging crews employed through various subcontra ctors are coordinated and mon itored. Personnel and equipment for the portable drilling operations are locally contracted, each group being supervised by a staff employee. Hand-turned portable flushing drilling units are normally sufficient to achieve required hole depths; however, where required, portable top­ drive power rigs are deployed. Party 314's QC group, coordinated by Senior Seismologist Andrew Pacey, is based in Rumba i, the administra tive cen ter, and consists of seismologists Wesley Hutaiulu, Willer Sitorus, and W irda Diusin. Team members use a top-drive power in the Duri steam flood 4-D area.

Crew activities radiate from a permanent basecamp equipped with al l the necessary facil ities to support full-time se ismic acquisition activities. The basecamp is located on the outskirts of Dur i, about 100 kilometers north of Sumatra's provincial capital, Pekanbaru. Additional temporary basecamps are established to meet operational needs. As the primary mode of transport (ot her than on foot through 1ung le ter­ rain) is by road, up to 80 vehicles are ass igned to the operation at any one time The routes follow a network of established roods that link the many oilfields os well os several main public roods existing within the con­ cession. Boots are available for river cross ings and helicopters are occa­ sionally deployed in remote areas or in emergency situations. As se is mic exploration continues in Indonesia, 3-D projects w ill be con­ ducted in long-established fields, and there exists both an increasing emphasis on the 4-D tool for reservoir monitoring and analysis and on the potential for regional exploratory 3-D surveys. While a continuing stream of tourists arrive in this so-called "l and of leisure" to relax, members of Western Crew 314 will rema in hard ot work pushing Indonesia's energy industry to new heights.

'S96l '1 I nhabited by Arab tribal chiefs far thousands of yems, the region known today as the United Arab Emirates (UAE) was a Trucial sheikdom during the 1500s, w it h Europeans es tablishing trading posts along its profitable coastline. Prompted by cen­ turies of relentless pirating in the Arabian Gulf, Great Britain intervened, becoming protector of the area during the 19th and 20th centuries. Fol lowing one sheikdom's declaration of independence in 1971, six other Arab states united in 1972 to form the UAE In addition to gaining geographical freedom, the state of Abu Dhabi has gained economic independence through its energy production. Until June, 1996, this energy-rich area was home to four Western Geophysical crews - two working onshore and two working in the transit ion-zone.

MOVE TO MODERNIZATION

Prior to the discovery of its vast oil reserves, Abu Dhabi, like its neighboring Emirates along the Truciol Coast, was a desert land, which may seem to have been left behind in the 20th century rush to modernize. Comprised of coral stone houses, palm frond huts, and a mosque built close to the ruler's fort, the old village of Abu Dhabi, although the capital of the Emirate, had neither modern schools nor hospitals, no electricity or water reservoirs, and roads were but beaten tracks across sandy wastes. Today, that village has grown into the major city of Abu Dhabi, one of the most sophisticated capitals in the Middle East. A dynamic metropolis of soaring modern office buildings, super highways and bridges, sumptuous villas, and lushly plant­ ed public parks, this capital city presid es over an ever-expand­ ing infrastructure throughout the Emirate. Tha nks to oi l revenues and the forward vision of Shaikh Zayed Bin Sultan Al Nahayyan, Abu Dhabi Em irate is a powerhouse of indus tr y and commerce and a key player in international affairs

CLIENT RELATIONS

Land operations in Abu Dhabi ore directed by Resident Manager Bruce Clulow, who promotes relations with the Abu Dhabi Notional Oil Company (ADNOC) and Abu Dhabi Company for Onshore O il Operations (ADCO) With assis­ tance from field supervisors Bi ll Browne, Bill White, David M o rrison, and Alan Tavender, Senior Instrument Supervisor Mike Zelum, Geophysicist Dr. Ismail Haggog, and accountants Adrion Cronstoun, Joe Chotoor and Far id Amr, logistic require­ ments ore satisfied

PARTY 755- EXPLORING THE NORTHERN TERRITORY

In Morch, 1994, Crew 755 began recording o perations in the central port of the prospect and progressed northward, taking advantage of a typically dry w inter for the Emirate to work in the extensive sabkha terrain in the prospect's northern region Working on a 3-D survey in the Rumoitho/ Shonoyel region, the crew used two sets of LRS 314 vibrators with four vibes per source, crisscrossing receiver lines, and form in g a diomond­ shaped grid pattern for data acquisition Doto were recorded using the Input/ Output System II on a 960-chonnel full spread of eight receiver lines.

I ' PARTY 769 - SETIING THE PACE IN THE "EMPTY QUARTER"

W it h its 60 vehicles, 28 tra ilers, 210 crewmembers, 49 mem­ 1 ber tent labor camp, 2048 channel VISION \' system , and all of the requisite equipment, Party 769 appeared virtually as a small town when seen from a distance. However, it is a sma ll town that knew how to pack up and move anywhere on short notice due to this experienced pace-setting crew's understand­ ing of desert operations . Located in a remote area bordering the Rub Al Khali (empty quarter) which stretches into Saudi Arabia, the Haliba p rospect has sparse vegetation, no permanent roads, ond few inhabi­ tants. The area is a full fledged "sand-sea" with dunes 100 to 200 m high With the wind blowing constantly and sand quick­ ly covering source line s and access tracks, the crew bottled lo keep cables , geophones, batteries, and Li ne Acquisition Module (LAM) boxes on the surface of the ever-shifting sands. The re were times when everyone in base camp, regardless of position, went to dig out equipment bu ried by blowing sa nd. From December, 1994 through February, 1995, Party 769 acquired data on a unique three-phase project for ADNOC, with two phases toking place in northwest Abu Dhabi at Al Ain, near the Dubai border. The crew shot a series of 2-D lines and saturation boxes that would be used for testing spread geome­ try and recording parameters. The area where the tests were conducted had a history of providing poor data on subsur face even ts. Interspersed among roll ing sand dunes 25 to 50 m high were camel pens and race tracks, agricultural areas, tree farms , and several small clusters of bu ildings. Party 769 used both vibrators and dynamite as sources to complete o 3-Component Wove test , a Swath Line tes t in both "X" and "Y" directi ons , and a Geophone Saturation test Doto were for­ warded to Western's London processing group for further analysis . While the data from Phase I were being analyzed, the crew proceeded 270 km south to Haliba to commence Phase II - o 3-D project covering 940 sq km. Using the VISION system, the

I crew acquired data for this prospect by recording each shot through 1320 channels w it h AHV Ill 351 vibrators, while Pe lton Advance II electronics were used to pound the ground 432 times on each source line. Up to seven bu ll dozers were used daily to cut source lines and keep access roads open. Driving across the sandy terrain near Haliba proved to be treacherous. Since safety is fir st and foremost w ith Party 769, crewmembers were not allowed to drive in sand without first being trained by an experienced desert driver. When ap­ (foreground from left) Party 769 proaching the top of sand dunes, drivers had to exercise cau­ Observer Alan Watson, Jr. Observe tion as sand near the steeper slip face of the dunes could easi­ Jason Pucil, and Safety Advisor And Hernandez make preparations for < ly give way.

Cable and personnel carrier (PC) buggies became everyone's best fri end. After Phase I tes ting was th oroughl y analyzed and decisions made concerning spread geometry and recording parameters,

Party 769 temporarily departed the Phase 11 prospect at Haliba and returned to Al Ain to shoot a 144 sq km 3-D, com­ mencing August, 1995. Data acquisition on the Al Ain 3-D was completed in January, 1996. Each source point was shot into 1440 chan nel s, and vibrators shook the ground continuously on each source line. The crew's diligence in laying out and recording the tests in Phase I and the analytical determinations made on those tes ts by geophysicists in Western's London office proved beneficial. Data acquired provided ADNOC an excellen t look at subsurface events In late January, 1996, the crew returned to Haliba to continue work on the Phase II 3-D project. Operations were completed in May, 1996.

PERSONNEL/EQUIPMENT

Involved in the day to day resou rce planning and management that al lowed the crew to meet its objectives were Party Man­ ager Neal Strickland, Assistant Party Manager Mike Murphy, and Crew Supervisor Dave Morrison. Leading the way as pathfinders for Par ty 769 were the sur­ vey crews . With their four Trimble 400 SSE GPS receivers, they blazed a trai l of source and receiver lines through the dunes, setting the pace for everyone else. C raig Thomas,

Party 769 vibrators Garry Rawlinson, William Boothe, and Khalid Mamood brought new meaning to the word "teamwork." Because of the distance away from the crew that they worked, all were experi­ enced in desert operations. One mistake can be life-threaten­ ing because help can be a long time arriving, especially if a search is involved. Responsible for bulldozer operations, Nasib Sher heads up ' j the line-clearing department Working with up to seven dozers, Nasib did an excellent job of making sure that the crew could get to the lines and that sand tracks stayed open so supplies got through to base camp. After receiving the VISION system at startup in November, 1994, the crew achieved success due to the talents of four observers - Alan Stobbort, Alan Watson, James Milam, and Danny Blais . Whether working in the recorder or on line, they were adept at quickly resolving problems and maintaining solid production. Junior observers Jason Puci l, Adrian Proco, Bernabe Corpuz, and Mohammed Munir were kept continually on the move changing LAMs, geophones, batteries, and cables as needed. Lab/cable technicians Po ul Cooper and Trevor Hill capably ass isted the recording crew Having many years of recording experience, they quickly analyzed crew problems in the tech lab, and provided solutions to the field almost immediately. They were also instrumental in keeping the base comp electri­ cally operational when ports and supplies were scarce. Working long, hard hours in 50 ° C heat, vibe techn icians Morty Rasmussen , Jerry Parry, Victor Arellano, and Mumtaz Rana kept the ten AHV Ill 351 vibrators pounding the gro und '-·.. ... with monotonous regularity.

the spectacle of camel racing I Since the area housed several camel race tracks, there were times when the recording crew had front row se ats as the recording spread passed a track currently holding races. As experienced mechanics performing preventive mainte­ nance on the crew's extensive equipment, no jobs were more important than those of Claus Mikkelsen and Bill O'Keefe. Their ability to make repairs by improvising and building parts from scratch was unsurpassed. Adept at diagnosing mechani­ ca l failures , they handled ma ny of the field repairs over the radio, thereby min imizing down time.
