Ardiseis與CGG完成高密度地震勘測
中國石化新聞網(wǎng)訊 據(jù)ONG網(wǎng)站3月12日沙特胡拜爾市報道，Ardiseis是阿拉伯地球物理和測量公司(ARGAS)的一家子公司，中東的地震勘測采集專家，其技術(shù)合作伙伴法國地球物理公司（CGG），已經(jīng)宣布成功地完成了世界上最高密度的陸上或近海的寬帶地震勘測調(diào)查。
這是一項雄心勃勃的挑戰(zhàn)，即從2000平方公里的超級密集的調(diào)查中，為油氣儲層提供具有代表性的寬帶地震數(shù)據(jù)，比迄今為止在世界范圍內(nèi)獲得的任何調(diào)查都要密集2到3倍。
為了實現(xiàn)以與傳統(tǒng)土地收購相媲美的速度和成本生產(chǎn)數(shù)據(jù)所需的超高生產(chǎn)率的收購，Ardise首次在埃及部署了CGG的無約束混合采集技術(shù)（Unconstrained Blended Acquisition technology）。
這一技術(shù)將現(xiàn)場操作優(yōu)化到極致，大量的振動器可以同時運行，并且不間斷地相互獨立運行。
CGG通過在其龐大的計算資源上運行其專有的復雜的混合算法，成功地將數(shù)據(jù)進行了混合。
阿帕奇(Apache)的埃及地區(qū)勘探經(jīng)理Joe Versfelt說:“自從2004年阿帕奇被授予西卡拉布沙租借區(qū)以來，已經(jīng)發(fā)現(xiàn)了19個油田，目前的生產(chǎn)能力超過5.5萬桶/日。
阿拉伯地球物理和測量公司(ARGAS)成立于1966年，是由沙特阿拉伯的工業(yè)化和能源服務公司(TAQA)和法國地球物理總公司 (CGG)合資成立的。
在其50年的歷史中，地震勘測數(shù)據(jù)采集一直是其業(yè)務的核心。
2007年之前，ARGAS公司專門從事于沙特阿拉伯王國境內(nèi)的2D和3D征地。

Ardiseis and CGG complete key high-density seismic survey
Ardiseis, a subsidiary of the Arabian Geophysical and Surveying Company (ARGAS), the Middle East’s seismic acquisition specialist, and its technology partner, CGG, have announced the successful completion of the world’s highest-density broadband seismic survey ever acquired onshore or offshore.
Apache set Ardiseis the ambitious challenge of delivering reservoir characterization-ready broadband seismic data from a 2,000-sq-km, ultra-dense survey,two-to-three times denser than any survey acquired to date worldwide.
To achieve the ultra-high productivity acquisition required to produce the data at a comparable pace and cost to conventional land acquisition, Ardiseis deployed CGG’s proprietary Unconstrained Blended Acquisition technology for the first time in Egypt.
This technique optimises field operations to the extreme, with a large fleet of vibrators operating simultaneously and independently from each other non-stop.
CGG successfully deblended the data by running its proprietary sophisticated deblending algorithm on its massive computing resources.
Joe Versfelt, Apache’s Egypt region exploration manager, said: 'Since Apache was awarded the West Kalabsha concession in 2004, 19 oil fields have been discovered and production capacity is currently over 55,000 bpd and growing.
ARGAS was established in 1966 as a joint venture between the Industrialization & Energy Services Company (TAQA) of Saudi Arabia and Compagnie Générale de Géophysique (CGG) of France.
Throughout its 50-year history seismic data acquisition has been at the heart of its business.
Until 2007, ARGAS specialized in 2D and 3D land acquisition in the Kingdom of Saudi Arabia.
