A quick resume on SEAPEX Meeting Chapter at Perth on 25th of March 2009 on Murray Street

Dear Explorers,

Summary of SEAPEX (by Peter Baillie-TGS Nopec)

The main idea of the presentation, I think to introduce how well the backscatter technology revealed the resolution to identify where the HC seep is on top of Seafloor, with examples taken accros Indonesia deepwater area of exploration.

A) SEASEEP:
1. High resolution multibeam bathymetri and backscatter which could image
- up to 100% seafloor topography, define structure trend and modern offset
- Identify location and concentration of HC seep for coring by using function of hardness of seafloor (impendance), roughness of seafloor and volumetric scattering. It works like a sonar signal)
2. Hull mounted sub bottom profiler (seismic to 100ms) to locate hazard, gas chimney and gas clouds)
3. Powerful combination with grav mag
4. Navigating the piston cores

B) PROJECTS
1. SO far in Indonesia TGS Nopec has these list :
- 2D seismic of 34000 line km across N sumatra, Sunda, Bone, Banggai Sula, Misool Onin, Seram, Jamdera, Kumawa and Cendrawasih
- Multibeam 400,000 km2
- GravMag 140,000 line km
- Sediment Cores
- Geochem area
- Heatflow probes

C) PROJECT EXAMPLES
1. ?Chirpline (Around Salawati Basin to SW)
Usng Backscatter Tgs claimed to have this analysis :
- 434 Carbon Isotopic ratio sets distinguished gas
- Biomarker analysis suggest that the SR come from Mesozoic as in NWS Australia, and Tertiary Marine
2. Cendrawasih Bay
-2006 Perception
Basement consist of Granit and exposed Gneiss along margin
Non prospective tectonic model
Neogene Rift
-Analisis taen in the eastern coast of Cendrawasih (waipago through) Bay along from Yapen Island
Mud Volcano is observedwith some HC effect seen on Seismic reflection
HC Seep observed in the ?fold belt which appears in seafloor
29755 km SEASEEP analysis project is heading forward

3. Andaman (North Sumatra)
-Multibeam seep project of 20626 km2
-2D Seismic line of 1464km
-?ForeArc Basin type (but TGS Nopec is willing to call this is not a classic foreacr basin but ?continuation of continental something)
-Analog for this type of Basin found at Japan and ?Alaska

Tgsnopec.com would be one of resource to dig out the infos, I would reckon

PESA (Petroleum  Exploration Society of Australia/ www.pesa.com.au) ,mengadakan Luncheon pada tanggal 21 Mei 2009 di Perth.

Pada kesempatan kali ini Dr. Moyra Wilson, dosen sedimentologi karbonat di Curtin University akan memberikan presentasi dengan judul Cenozoic carbonate and Their Reservoir development in SE Asia. Dr Moyra sebelumnya adalah dosen di Royal Halloway University – London, beliau juga pernah memenangkan kategori poster terbaik di konferensi IPA (Indonesia Petroleum Association) tahun 2008 di Jakarta.

Bagi yang tertarik tentang apa, bagaimana dan potensi dari batuan karbonat tersier di SE Asia, nampaknya paper ini akan sangat menarik. Sebagai perbandingan batuan karbonat tersier yang sangat terkenal di Jawa Barat adalah formasi Rajamandala yg berumur Oligo-Miosen.

Berikut adalah abstrak dari Paper nya :

Details:
Cenozoic carbonates and their reservoir development in SE Asia

Almost half of SE Asia’s considerable hydrocarbon reserves are contained in carbonates. Although the majority of economic discoveries are in Miocene buildups, Paleogene reservoir intervals also occur. However, there is little data on how the spatial and temporal variability in depositional and diagenetic conditions influence the considerable heterogeneities in reservoir quality often encountered.
Paleogene carbonates in SE Asia are commonly dominated by larger foraminifera. These carbonates developed on or around the margins of highs within subsiding basins, and typically form large-scale platforms or isolated shoals. Good poroperms may be preserved in shoal or redeposited carbonates lacking micrite. Secondary porosity development is due to fracturing, chemical dissolution during burial, or as karstic cavities. However, the lack of aragonite, paucity of eustatic fluctuations and deposition in generally subsiding environments reduces the potential for vadose or meteoric leaching. In comparison, Neogene carbonates often contain abundant aragonitic bioclasts, such as corals. Neogene carbonates typically develop as reefal buildups, shelfal deposits or as isolated platforms. Active Neogene compression in SE Asia resulted in increasing subaerial emergence, and many of the platforms were affected by tectonics or eustacy. Compared with Paleogene limestones, poroperms are generally higher in Neogene carbonates and interparticle, biomouldic, vuggy, cavernous and fracture porosities all occur. This evaluation of variability in SE Asian carbonate reservoirs provides much needed data as the hydrocarbon industry focuses on improving recovery from existing fields and exploring for new reserves

Brur, Bagi yg sedang berada disekitar Australia, APPEA (Australian Petroleum Production & Exploration Association) akan mengadakan konferensi tanggal

31 May – 3 Jun 2009

di Darwin Convention Centre, Northern Territory – Australia.

Sebagaimana konferensi  IPA atau IAGI  di Indonesia, pada acara ini akan diadakan berbagai presentasi paper dan poster serta exhibition yang berkaitan dengan bidang Eksplorasi dan Produksi di Australasia (incl. PNG-Papua New Guniea)

Salah satu agenda pemerintah Australia pada event ini adalah mengumumkan blok eksplorasi di daerah Australia untuk bid round tahun 2010

Salam GEA

Teman-teman, jangan lupa kalo sebentar lagi akan segera dimulai minggu UAS dari tanggal 18 Mei – 1 Juni 2009. Jadi persiapkan diri kalian dari sekarang! Berikut adalah informasi lebih lengkapnya:

Maaf, mungkin kalau gambarnya kurang jelas.

Dan satu lagi, sekarang sistem pengisian kuesioner bukan dengan menggunakan kertas lagi seperti dulu, tapi sekarang sudah beralih ke online, silahkan diakses melalui http://kuesioner.itb.ac.id. Untuk username dan password sama dengan yang digunakan untuk mengakses http://ol.akademik.itb.ac.id. Sebaiknya cepat, karena batas akhir pengisian kuesioner adalah tanggal 16 Mei ini alias hari Sabtu minggu ini.

Have a great day everyone!

thanks buat gebot puti yang uda bikinin account untuk jadi contributor di SurGe.

kali ini, gw mau kenalan dulu deh sama adek2 yang lebih muda dan bagi2 tips buat yang mau berangkat karsam.

nama gw cessy angkatan 2002, dilantik jadi gea tanggal 5 mei 2003. jangan ketuker sama chessy angkatan 2001 ya, atau jangan juga ketuker sama adya 2005, karena kebetulan nama panjang gw juga ada adya2 nya.

SurGe jaman dahulu kala bentuknya mungkin mirip mini tabloid (paling enggak waktu gw megang SurGe), bentukan SurGe yang sekarang lebih mantab dan gw harap bisa terus diwariskan ke angkatan berikutnya. Amin.

nah sekarang buat temen2 yang mau berangkat karsam! siapkan mental dan fisik! kalau dulu yang namanya “diksar” itu uda dianggap menyiksa batin dan tenaga kalian, karsam terasa lebih nyiksa kalau kalian ga siap.

persiapan kuliah yang diadaain Pak Bambang dan tim kayaknya uda oke banget, sampai pemilihan asisten yang mulai tahun kemaren harus melewati tahap wawancara dan hanya dipilih asisten yang TA nya TA A (gw termasuk asisten yg ga lolos kualifikasi, hehe).

yang penting adalah persiapan temen2 sebagai peserta. pikirin bener2 apa yang bisa membuat kalian nyaman selama 1 bulan di lapangan jauh dari keluarga, temen kostan, dan mungkin pacar. bagi yang harus terus ngabsen sama pacar, ga usah khawatir, uda ada sinyal kok di karsam, sejak angkatan 2003 karsam.

sekedar perbandingan sama apa yang gw bawa sewaktu karsam ya, mungkin bisa dijadikan acuan.

semua alat tulis gw kasih nama, sama kayak waktu diksar, paling ga kalo ada yg minjem gampang nyarinya, susah loh nyari alat tulis kalo lagi pusing bikin laporan lapangan. hehe. alat tulis yang gw bawa gw usahain selengkap mungkin, dari mulai bolpen, pensil, isi pensil, penghapus, pensil warna, spidol marker, spidol biasa, rautan, penggaris panjang, penggaris pendek, penggaris segitiga, dan busur. mending bawa lengkap daripada bingung disana harus beli dimana.

baju, usahain bawa baju yang nyaman untuk dipake di cuaca yang panas, dan biasanya pas materi-materi tertentu selalu hujan, misalnya LK, mitos ini Pak Bambang sendiri lho yang bilang, tiap LK itu biasanya ujan. jadi bawa jas hujan juga yang nyaman dipake. jakun pastinya jadi favorit outfit selama disana, jd berbahagialah temen2 yg punya cadangan jakun.
