I hope that this note finds you very well. These are exciting times for M-OSRP, and we are very busy and very happy. Attached please find the schedule of sponsor-only delivery of documented 2019 M-OSRP speed-up versions of internal multiple attenuation and elimination codes. Separately, I thought it useful to extract ( please see below this e mail) a key and very important paragraph from the attached schedule. That message assures that sponsors receive a return on their investment( ROI). Please do not hesitate to contact me with any questions or interest in further detail. As always we thank you for your encouragement and your support. Warmest best regards, Arthur
Extracted paragraph from the attached Schedule of Delivery with a key and important message regarding the 2019 M-OSRP speed-up internal multiple code deliveries
The documented codes will provide several items: (1) a step by step description of the preprocessing required before the data is ready for internal multiple removal, (2) the detailed mathematical derivation that resides behind the 2019 M-OSRP IMA and IME speed-ups, and (3) the factor that is called upon and utilized after a finite term elimination algorithm is applied to mitigate the difference between that finite term algorithm and the complete infinite term elimination sub-series, without computing higher order terms.At this time, the latter two items will only reside within the M-OSRP sponsor-only proprietary codes, and documentation, in the sponsor only website- and will not be made public or published.That’s the ROI for sponsors.
To provide a context to the priority that the petroleum industry, and hence M-OSRP, place on multiple removal please see the video in the link below. Why do we need to remove multiples?
I hope that you find the video presentation ( an invited key-note presentation at Ecopetrol Dec. 8, 2018 in Bogota Colombia) to be worthwhile, informative and interesting. The video begins by asking ‘Why do we need a new perspective?’ ‘What exactly is new?’ ‘And what are the practical benefits and value -and resource allocation consequence,

Research breakthrough for multiple removal from M-OSRP : Increased seismic effectiveness, efficiency and impact for exploration, production and CO2 management
Among the current highest priority seismic challenges and impediments to making successful exploration drilling decisions and optimizing reservoir and Carbon management, occurs when a type of multiply reflected event ( an internal multiple )interferes with a single reflected event ( a primary) at or above a reservoir target.
That situation is extremely common, and occurs in both offshore (e.g., sub-salt deep water Gulf of Mexico, offshore Brazil, Australia, North Sea…) and on-shore conventional and unconventional plays( e.g., over the entire Middle East, the Permian Basin, …) .
The M-OSRP group at UH has pioneered and has delivered the only free surface multiple elimination codes and is currently delivering the internal multiple elimination concepts and algorithms ( please see the two attachments) that(1) require no subsurface or near surface information ( the latter is essential for on-shore plays) and (2) will predict and surgically remove the multiple without damaging the interfering or proximal primary.

Seismic reflection data is used to locate and produce hydrocarbons. Seismic reflection data consists of single reflected events and multiply reflected events. Single reflected events are called primaries and are used to locate and identify hydrocarbon targets and for optimizing reservoir development and Carbon management. Multiply reflected events must be removed to achieve those objectives.
Among the current highest priority seismic challenges and impediments for making successful exploration drilling decisions, and for optimal reservoir management, occurs when a type of multiply reflected event (called an internal multiple )interferes with a single reflected event ( a primary) at or above a reservoir target.
All currently used methods for removing internal multiples will damage a nearby or overlapping primary, and that in turn will contribute to dry hole drilling and suboptimal reservoir development wells.
That situation is extremely common, and occurs in both offshore (e.g., sub-salt deep water Gulf of Mexico, offshore Brazil, Australia, North Sea…) and on-shore conventional and unconventional plays( e.g., over the entire Middle East, the Permian Basin, …) .
The M-OSRP group at UH has recently pioneered and is delivering the only internal multiple elimination concepts and algorithms that(1) require no subsurface or near surface information ( the latter is essential for on-shore plays) and (2) will predict and surgically remove an internal multiple without damaging an interfering or proximal primary.
However, these new and much more effective prediction algorithms become extremely computationally demanding and that reality represents a serious challenge and impediment to realizing its potential and impact. In fact, their computational demand makes these extremely capable and effective algorithms far outside an acceptable run time and hence practically useless. To have an effective and impactful response requires both a new level of predictability and a commensurate advance in computational efficiency to allow a reasonable and useful turnaround.
Professor Fang Liu working with colleagues within M-OSRP has made a major advance in computational efficiency that turns what is currently far outside a reasonable compute time, to become well within a reasonable and acceptable time frame.
To grasp the significance of this new 2019 M-OSRP speed-up a current run time of more than several years will be reduced to a few days, making the currently impractical and impossible, reasonable and realizable. The combination of heighted effectiveness and efficiency will allow many off-shore and on-shore plays that are currently precluded and inaccessible to become open and accessible and will provide a step change improvement in reservoir development and CO2 management.
