Written questions must be received no later than May 24, 1996. BDM seeks a proposal for the turn-key operation of both a high-resolution 3-D seismic survey in a 9-mi2 area in Osage County, Oklahoma, about 25-miles northwest of Bartlesville during the Summer of 1996, and for processing of the field tapes from this work. The focus of this project is to develop, identify and test new and innovative seismic survey designs and procedures, field equipment and practices, processing and interpretation procedures, and software to reduce costs and increase efficiency for independent seismic contractors and oil and gas operators. The work should demonstrate how 3-D seismic data, when integrated with state-of-the-art data processing and interpretation software and techniques, can aid in the identification of hydrocarbon resources in subtle structural and stratigraphic traps, and to identify ways to cut the planning, operating, processing and interpretation costs of 3-D seismic surveys for small, independent operators. The proposal can include innovative designs or procedures for location surveying, field-work planning or management, sources, patterns, frequencies and frequency generation or management, recording equipment, processing or interpretation methodologies, applications, or equipment, etc. Proposals must include detailed projected cost breakdowns and schedules. State-of-the-art equipment and field procedures, innovative concepts in design, management, processes or equipment will be key in the award of this project. Costs, practices, and techniques used on this survey will be monitored by BDM personnel, to identify and record ways and means of increasing efficiency, improving operational practices and cutting costs for the small operator undertaking a similar survey. The survey area consists of gently-rolling, gullied prairie and grazing upland in the west, and cultivated fields on an alluvial valley floor to the east. Low bluffs and ramping slopes separate the areas. The surface is mostly clear, but wooded areas line gullies. Surface elevations vary from 700-950'. The area is crossed by one highway and 3 paved roads. Target formations range from Pennsylvanian channel sands, below 1000-1500', through granite washes, 3500-4000' deep. The basement should be a strong reflector at the base of the section. Target reservoir formations include very thin and narrow units at a wide range of depths, including feather-edge sand pinchouts, unconformities, and meandering channel sandstones. The targets generally have low dips. The strata are mostly sandstone and shale, with occasional limestones. Lithologies change laterally quite rapidly. These units are difficult to image with 2-D techniques. The project is attempting to demonstrate that 3-D techniques, when used with state-of-the-art instrumentation coupled with optimal data acquisition and processing parameters can image these subtle features over this depth range, and that expenses can be lowered to the point where 3-D surveys can be cost-effective for the small operator. Explosive sources will not be acceptable. The source must be Vibroseis or other non-invasive source. Expected signal frequencies will be in the range of 20-100 Hz. Source and recording equipment must be capable of gathering high-resolution seismic data with fidelity. Maximizing the signal to noise (S/N) ratio over a broad frequency band is very important due to the thin nature of the target beds and subtle characteristics of the traps. Amplifiers will need to have low system-noise properties and a large dynamic range, around 120 dB, with a precision of around 24 bits. Proper selection of filters (such as pre-emphasis filter, for the suppression of high-amplitude, low-frequency noise), quality A/D converters and digital-data storage devices, and a high number of recording channels will be crucial to the survey. The seismometers must be capable of recording a broad band of data, especially in the high-frequency ranges. The suppression of low frequencies and ground roll effects will be very important. Field practices like geophone-ground coupling, precise location surveying, etc. must be closely monitored. A swath or full-range 3-D template design, or variations, is recommended. This may be modified to get more azimuths and higher fold. Other designs may be acceptable if they satisfy the data-resolution specifications mentioned above. The seismic lines should generally trend NW-SE and NE-SW, perpendicular to local fracture orientations. Source and receiver spacing should be approximately 110 feet, but minor variations will be acceptable where mandated by field conditions. Source and receiver line spacing will be dependent upon the number of recording channels. Assuming a 480-channel system, the estimated source line spacing would be 330' and the receiver line spacing would be 660'. Sub-surface bin size should be approximately 55' x 55'. CMP fold should be at least 20 in most of the survey area (InlinexCrossline = 5x4). Target depths are 1000-4000'. The sample rate should be 2 ms with a record length of 3 seconds. Offset ranges should be 55' minimum, 6600' maximum. Sweep frequency should be 8-20 Hz, non-linear downsweep, 9 db with a sweep length of 10 seconds. 4 vibrators should be deployed, synchronized to improve signal characteristics. Non-linear sweeps are recommended, emphasizing higher frequencies, to optimize S/N ratio. A field test will be required at the outset to determine the noise characteristics of the area. This information may be used to optimize geophone and shot arrays for noise attenuation. A final decision on the geophone layout pattern will be made upon completion of this test. A nearby seismic survey, approximately 9-mi to the west, successfully used 12 geophones/group, with 6' intervals between geophones. The operator of the field acquisition survey will be responsible for all phases of survey preparation and setup, including obtaining of all required permits and access rights, surveying, field activity, data recording, cleanup and restoration, dispersal of damages, if any, etc. The operator of the field acquisition survey will be responsible for all phases of survey preparation and setup, including obtaining of all required permits and access rights, surveying, field activity, data recording, cleanup and restoration, dispersal of damages, if any, etc. The operator must ensure that no liability is incurred by the Department of Energy for surface damages or other matters. The contractor must deliver tapes containing 3-D data volumes in a format which can be downloaded onto a Sun SPARCStation 20 workstation or Pentium PC for in-house interpretation. Selection of a company will be based on the potential of the applicant to cut the planning, time and/or costs for processing and interpretation of 3-D seismic surveys for small, independent operators. Successful target imaging and cost reduction for small-scale surveys are primary project goals. The proposal can include innovative designs or procedures for planning or management of processing activities, equipment, software, or interpretation methodologies, etc. Proposals must include detailed projected cost breakdowns and schedules. State-of-the-art concepts, equipment, procedures, and software will be key in the award of this project. Costs, practices, and techniques used for this survey will be monitored by BDM to identify and record ways and means to increase efficiency, improve operational practices and cut costs for small operators contracting for similar processing. Target formations in this project include extremely thin beds with rapid lateral lithologic changes, at depths between 1000-4000'. An extremely good S/N ratio over a broad frequency band will be key to success. Processing steps should include reduction to a common datum, wavelet processing (including deconvolution and time-variant spectral balancing to attenuate low-frequency noise), refraction statics, datuming, residual statics, pre-stack coherent-source-generated noise attenuation, velocity analysis, DMO in common offset, common reflection-point gathers, post-stack noise attenuation, migration-velocity analysis, migration, plus any other processing procedures that will improve S/N ratio while preserving a large bandwidth with higher frequencies. Innovative processing techniques/equipment that can reduce time and/or processing costs can be suggested, but must be approved by BDM before the above list is modified. Newly-designed processing steps or new hardware/software innovations that can generate reliable data displays will be encouraged.
