- Description
- This letter is in response to questions concerning solicitation 06CRSS0022, Gas Hydrate Analysis. 1.) Due to the highly variable nature of seismic data quality, previous work flows may not work on data significantly different than that of the data used to develop the USGS work flow. In light of this, is there any way that bidders can view a small subset of the seismic data for the project to aid in their bidding Data is sufficiently described in the statement of work. 2.) Does the USGS already have the log curve data on hand that would be loaded into this project? If so, what types of log curves are typically available for this work? In particular, how many wells with sonic log curves are available that would tie the 3D data mentioned in the bid package? To date, the USGS has available logs from approximately 70 wells within the area of interest associated with the proposed project areas. Most of the 70 wells have associated sonic log curves. 3.) Will there be technical assistance during the course of this project, and will it be able to provide assistance in performing any calculations of resistivity to sonic velocity within the permafrost interval and assist with the saturation and thickness calculations from thin bed hydrate analysis for the investigations? USGS personnel will be available throughout the contract interval to provide technical expertise in the conversion of resistivity logs to sonic logs in areas of poor hole quality and problematic intervals within the permafrost zone. 4.) The bid document has several references to "USGS project interpreters". How many man hours will be provided by the USGS internally and what will be their role in the project? Will they be under the guidance of the successful bidder There will be some limited interaction between the USGS technical representative and the successful contractor. The interaction will be in a preliminary phase only. The USGS technical representative will not be under the guidance of the successful contractor. 5.) One of the "deliverables" in the Final Project Summary, #2, is that the "Contractor shall provide a report describing any processing of data required prior to interpretation." If processing or reprocessing of the seismic is required prior to interpretation, this would significantly impact any time line developed for the project. Is it expected that the project deadlines would be adjusted to accommodate possible months of delay, or are the USGS technologists expecting that these would be minor issues that could be dealt with quickly in-house, perhaps during the data loading phase? The expected processing of data required prior to interpretation is only anticipated to relate to minor issues such as post-stack balancing, filtering, etc. There is no anticipated reprocessing of pre-stack data involved on the part of the successful contractor. Any pre-stack re-processing will be done by USGS personnel in-house. 6.) Section F.4 GS0917 demands a schedule of a five day work week on the project at the USGS site. Does this assume that a single individual will be providing all of the work on the project The contractor can arrange the schedule as long as it provides the deliverables listed in phases one and two within the time period in clause GS0910.
