About WellBid Inc.

WellBid provides business-to-business e-commerce application services for the upstream oil and gas industry, increasing efficiency for both producers and service companies in the negotiation and purchase of well-related equipment and services. WellBid's secure and neutral Internet service offers a unique business solution that streamlines workflow related to the procurement process. Using WellBid, an oil and gas producer, operator or drilling engineer specifies the detailed physical, geographical and scheduling requirements for the equipment and services needed to drill and complete new wells or multi-well projects, and to maintain or repair existing wells. These requirements are automatically sent through the WellBid service as bid requests, requests for quote or requests for AFE proposal to the operator's list of selected vendors operating in the relevant geographic region. Vendors then respond to these requests through WellBid, beginning the two-way communication to refine and negotiate the buyer's requirements, saving time and money over traditional business practices through the power of e-commerce.

WellBid is headquartered in Denver, with field offices in Houston, Midland, and Calgary. Additional offices are planned for Dallas, Lafayette, Oklahoma City, Bakersfield, and Traverse City.
