  • 河北省11选5开奖结果:Exploring Subsalt Plays

    后一万能码 2期内中 www.qgqx.net Significant petroleum systems around the world are to be found hidden below salt canopies. These structures are difficult to illuminate and hazardous to drill through without proper insight. They are deep and often over-pressured. Salt can be mobile, layered and “dirty”. Wide-azimuth, and now, full-azimuth seismic has provided a step-change in illumination, shedding light on salt structures and what lies below. Low-frequency seismic recording and imaging increases penetration. Gravity gradiometry defines salt boundaries. Together, these technologies can delineate salt structures more accurately and deliver better images of sub-salt plays. The investment in drilling sub-salt is substantial. Use the best resources available to you to get results you can trust.

    Exploring Subsalt Plays

    Advanced Subsalt Toolbox

    From the Gulf of Mexico, to the Atlantic margins and the Mediterranean, there are prolific petroleum systems related to rift systems which are capped by evaporites. The nature of this “salt” varies from thickly layered evaporite systems to mobile massive halite which forms diapirs and canopies.

    The challenge of imaging subsalt plays has been a catalyst for seismic innovation. From the advent of wide-azimuth seismic surveying to the powerful combination of full-azimuth illumination, ultra-long offsets and BroadSeis? broadband low-frequency penetration with StagSeis?, CGG has pioneered subsalt seismic. We are recognized leaders in subsurface imaging and our regional expertise coupled with our advanced subsalt imaging toolbox is second to none. We devise the most detailed salt velocity models, we deal with intra-salt multiples, and use the latest developments in RTM imaging such as Orthorhombic anisotropy and vector offset output to provide the best results.

    Gravity Gradiometry is a proven tool for delineating salt bodies which can be used to refine and enhance salt body interpretation and Falcon?Plus offers the highest sensitivity of all airborne systems.

    Salt interpretation is a critical step in the imaging process. Salt scenario testing can be performed based on expert input from our geoscientists. New interpretation technology with SaltSpark can accelerate this step, by accurately defining and wrapping salt bodies, no matter how complex.

    For tough salt imaging challenges, rely on CGG’s leading expertise and technology.
