Abstract:
The presentation will consist of a technical discussion of environmental pilot/feasibility tests. Various technologies and methodologies, such as Soil Vapor Extraction (SVE), Enhanced Vacuum Recovery (EVR), also referred to as Vapor Extraction-Groundwater Extraction (VEGE), Dual-Phase Vacuum Extraction (DPVE), Air Sparging (AS), and SVE Quick Tests (QTs) will be presented. The results of a recent pilot test will be discussed to point out the many variables and outside forces that can affect precision testing.
Biographical Sketch:
Since 1957 Jim Sadler has been associated with oil refining, marketing and environmental remediation following his graduation from the University of Texas with a degree in mechanical engineering. After his first job with Ethyl Corporation as an automotive engineer, he was employed by Tenneco in the Refining and Marketing department, where he was directly involved in developing the "convenience store with gasoline" concept and became VP of marketing.
He later decided to start his own marketing company, primarily involved with developing the concept of self-service gasoline. In eight years, Autotronic Systems Inc. was built to 750 self-service stations in 23 states. After the company was sold to Sigmor, he became a consultant for Coral Petroleum to develop its marketing in upstate New York and Pennsylvania. This was his introduction to environmental problems associated with USTs.
In 1991, Jim's wife Leiselle Mathews started a marketing company for the S.A.V.E.(trademark) remediation system. Jim and Leiselle recognized a developing trend and demand for pilot testing, and the company rapidly became a service company. The company developed the methodology for the reporting of accurate and useful data for CAP plans. Since 1991, AcuVac Remediation, Inc. has conducted over 1,500 pilot tests. Mr. Sadler has over 10,000 hours of on-site testing.

Talk Abstract:
INTRODUCTION
The Timor Sea (Australia/Indonesia) has had a remarkable string of successes beginning with the discovery of oil in Elang field in early 1994. Oil discoveries in an area that was previously thought to be mainly gas prone have captured the interest of the industry, and new geological concepts and better seismic technology have lowered exploration risks. New significant gas pools are also being found or actually re-found in the case of one discovery. Gas development plans will rely on the synthesis of various LNG projects and the improvement of South East Asian economies.
SYNOPSIS of REGIONAL TECTONICS
The discoveries examined in this paper are situated within the northeastern Browse Basin and in the Bonaparte Basin. (See Figure One) In this region, Late Jurassic rifting formed a horst/graben topography in the basin centers and tilted terraces on basin margins. The Kimmeridgian through early Valanginian rift sequence is represented by alluvial to submarine fans shed locally off intermittantly active basin margin faults and by restricted marine shales of good source rock quality in the basin centers. The last crustal extension of the Mesozoic produced the mid-Valanginian unconformity that represents the final separation of Australia and India. Post rift thermal sag marine shale deposition then predominated until a Mid Cretaceous regional lowstand produced erosion on the margin of the Londonderry High and subsequent deposition of clastics. The early Tertiary was mainly tectonically quiescent, with passive margin carbonate marine shelf sedimentation predominant; however, inversion events have been recognized locally in various parts of the basin. Oblique collision of the northern Australian margin and the Indonesian plate began in some areas in the mid-Oligocene, and culminated in regional major reactivation of older faults in the late Miocene. This collision resulted in the beaching of numerous oil and gas pools in the Timor Sea and re-migration of hydrocarbons. Rejuvenation along faults occurs at present; for example, pre-drill presence of hydrocarbons in the Cornea area was indicated by a seismic amplitude anomaly, by radar imaged oil slicks and by positive results of a water bottom "sniffer" survey.
RESERVOIRS
With the exception of Cornea field all the pools discussed in this paper include some part of the Bajocian to mid-Callovian Plover Formation and/or the mid-Callovian through early Oxfordian Elang Formation. These reservoirs are interpreted to have been deposited in an overall transgressive setting ranging from fluvial channels to tidally influenced estuarine shoreline sediments to upper shoreface units. Cornea field reservoirs are Early Cretaceous alluvial to fluvial sands deposited on the southern margin of the study area.
STRUCTURAL STYLE
The majority of the Jurassic accumulations are pooled in three-way closures against faults. Laminaria and Bayu/Undan fields are exceptions in that they are large regional highs with four-way closure. Cornea field consists of a four way closure created by drape over a basement high. 3D seismic has been helpful in confirming fault presence and extent. Seismic resolution of the surface of Jurassic objectives is often difficult and interpretation must include identifying truncations at unconformity surfaces.
