The paper entitled “Optimization of Infill drilling in Whicher Range Field in Australia” looks at the various attempts to get the gas out of the range and concludes that 58 new wells drilled in two stages will optimise the production of the gasfield. The Whicher Range seismic data interpretations from 2004 and … The second area is the Whicher Range gas field, which covers an expansive area south of Busselton, just east of the Capes. It focuses on the long, complex history of largely unsuccessful endeavours designed to appraise the large, onshore, Whicher Range gas field in the southern Perth Basin. tional and diagenetic properties on pore system of tight sands in the Whicher Range gas field. Sensitivity analysis of seismic response to the fluid content of shale gas Large gas reserves are known to exist under the range. It is especially alarming that the Whicher Range gas field, in which this accident occurred, is located within a Priority 1 water catchment area for the Margaret River region. Get PDF (17 MB) Abstract. The Whicher Range field, just south of Busselton, is estimated to contain as much as 4 trillion cubic feet in prospective resources. In the onshore south Perth Basin, Gingin 1 has produced gas but is now depleted. But the complexities associated with unlocking its tight gas reserves have since frustrated commercialisation efforts by a string of hopefuls, including Pennzoil and Amity Oil. It consists of stacked and isolated lenses of … This is a compendium of reports presenting findings of geoscience research covering a broad spectrum of topics relating to the characterization of unconventional, tight gas sands. However, the limited drilling that has occurred in this part of the basin confirms the presence of the key components for a working petroleum system, as evidenced by the Whicher Range gas field to the south. A poor understanding of the reservoir properties within the Whicher Range area has led to unsuccessful exploration and appraisal strategies. Abstract. It is also inferred that reservoir simulation combined with MWM requires less data and much simpler as well as faster compared to standard reservoir simulation for optimizing an infill drilling plan for alike of Whicher Range tight gas field. There are limited studies characterising the Willespie Formation, a Permian tight gas sandstone in the southern Perth Basin of Western Australia. Geological reservoir modelling for Whicher Range Field tight gas sand . The Whicher Range in the southern Perth Basin is a poignant Western Australian example of the lack of certainty in methods used by unconventional gas proponents to investigate the risks to aquifers. The Whicher Range field is located in an existing high-growth, deregulated gas market of 600 terajoules per day. A poor understanding of the reservoir properties within the Whicher Range area has led to unsuccessful exploration and appraisal strategies. whether the western bounding fault has sealing capacity to retain hydrocarbon gas It was originally drilled in 1968 and there have been significant flows. The field is located in a large anticline structure in the Bunbury Trough, and five wells have been drilled in this structure so far. Whicher Range contains 46.4 billion cubic metres of gas that was originally considered uneconomical, but is currently being tested to see if economic gas flow rates can be sustained. It was first discovered by Union Oil in 1968. Distance from Whicher Range Gas Field 13.72km N. Temperature Feels Like Rel. Gas explorer CalEnergy has pulled the pin on activities at Whicher Range, announcing it isn’t worth forging ahead and the wells will be cemented shut. Whicher Range (WR) field, located in the Southern Perth Basin, is a large, low permeability and very heterogeneous gas reservoir. Whicher Range is a conventional gas field which does not require the use of hydraulic fracturing which is also known as fraccing. A) Stratigraphy succession of the southern Perth Basin (Playford et al., 1976). Geological Setting Perth Basin is an N-S trending, long and narrow and asymmetrical rift basin (Figure 1(a)) located in the south-west of Western Australia [11]. According to the Department of Planning(2011), "a Priority 1 source protection classification is assigned to planning Download : Download high-res image (1MB) Download : Download full-size image; Fig. Gas in place estimates range up to 5 tcf and a gross gas column height of about 650m is identified for this field. By Cesar Daniel Orsini Martin. CalEnergy had hoped to develop the resource as a conventional project and deliver 1 million cubic feet of gas per day as a pilot project. The conventional gas company completed a sidetrack drilling last year using a managed pressure drilling technology in … By Cesar Daniel Orsini Martin. Diagenetic events (compaction and cementation) have severely affected the pore system. B) Location of the Whicher Range gas field in the Perth Basin (modified after Sharifzadeh, 2008). The Margaret River and its tributary Margaret River North also rise from the Whicher Range and then flow west before discharging into the Indian Ocean. Consequently, the main factors controlling the reservoir quality, lateral reservoir connectivity and fluid flow mechanism remain unknown. The Whicher Range tight gas sand field is located 280 km south of Perth in the Bunbury trough of the South Perth Basin. Limited exploration in the offshore Perth Basin has identified three discoveries. Whicher Range Energy’s website says the company drilled five gas wells in the Busselton Shire before 2000. 2. The Whicher Range field, the target of this study, with gas trapped in deep burial (~4 km) tight sands is one of the most im- portant fields of the basin. The gas field under the Whicher scarp near Busselton is one of the largest in Australia, says Brendan. Testing at Whicher Range gas field is due to resume in September, with CalEnergy Resources hoping new techniques will tap into potential gas reserves. 2. Coonawarra. However gas flow test rates have been below expectations, typically about 1 … The eastern boundary is the Darling Fault, and the basin extends offshore to the Simulation uncertainties in tight gas reservoirs; Case-study on Whicher range field in western Australia Author: Ehsan Pouryousefy, Lukman Johnson, Mohsen Ghasemiziarani, Felany Wijaya and Jeffry Viriya Simulation uncertainties in tight gas reservoirs; Case study on Whicher range field in western Australia reservoir model and the model calibrated with available production data to be used to evaluate the reservoir behavior and possible future production scenarios. It used 1.2 million litres of diesel to frack the Whicher Range Gas Field in 2004, according to an email from Environment Minister Norman Moore’s office to the No Coal!tion, the August 19 Busselton Dunsborough Times reported. Tight gas sands in Whicher Range Field of Perth Basin show large heterogeneity in reservoir characteristics and production behavior related to depositional and diagenetic features. Whicher Range 5 Located 20 km south of Busselton, the Whicher Range field was discovered in 1968 with gas located in the Permian Willespie Formation, at a depth of approximately 4000 metres. Discovered over 30 years ago, the field is estimated to be over 4 trillion cubic feet in size. Exploration of the basin to date has been primarily focused to the north, with the southern portion having only been lightly explored. Geological reservoir modelling for Whicher Range Field tight gas sand . “The Whicher Range gas project has the potential to totally transform industry in the South-West by creating a massive new, clean energy source to encourage additional value adding industries and thousands of new jobs and opportunities,” the Minister said, during a visit to the Whicher Range … “the Whicher Range field is an encouraging analogue and demonstrates the Sue Sandstone play works in an adjacent basin sector.” The main geological risk associated with Leschenault is one of cross-fault seal, i.e. The well flowed gas to surface but at non-commercial rates. Up until 2014 there was some thirteen oil and gas discoveries within the onshore north and central Perth Basin, plus additional discoveries outside of this area such as the offshore Cliff Head oil field and onshore Whicher Range gas field (located in the far south of the basin). Whicher Range Gasfields Limited: Gas: 10: WRG: Whicher Range Gasfields Limited was incorporated on 12 July 2001 for the sole purpose of directly participating in the exploration activities being conducted on the Whicher Range gas field and adjacent areas contained within the Exploration Permits 408 and 381. There has been gas exploration going on for years at this Whicher Range Field and only the Amity Oil NL holds the current license for the oil explorations permits (EP’s), EP’s 408 and 381, in the South Perth Basin.
