Seismic Exchange Inc.

Seismic Exchange Inc., doing business as Sei, provides geophysical surveying and seismic data products to federal agencies as a sole-source prime contractor, operating as a self-certified small disadvantaged business headquartered in Houston, Texas. The vendor competes on full-and-open procurements without set-aside designations; recent awards include both no-set-aside and total-small-business designations, though Sei's SDB certification does not anchor a systematic set-aside posture across its footprint.

Sei's capability portfolio centers on two-dimensional multichannel seismic reflection data acquisition, processing, and delivery, supported by geophysical surveying and mapping services under NAICS 541360. The vendor operates primarily as a data provider and broker for existing seismic surveys rather than as a field acquisition contractor. Recent representative work includes a $403,520 firm fixed-price delivery order issued by the U.S. Geological Survey on April 21, 2026, for seismic data as product with completion scheduled for April 20, 2027; a $150,000 delivery order from February 26, 2026, for 2D seismic reflection profiles related to the Craddock project; and a $395,200 delivery order from March 26, 2025, for seismic data products with service level agreements. All three delivery orders are placed under Sei's five-year, $2.99 million Indefinite Delivery Contract with USGS awarded September 1, 2024, and effective through August 31, 2029.

Customer concentration is severe and concentrated within Interior Department geosciences work. The Department of the Interior's U.S. Geological Survey Office of Acquisitions and Grants accounts for 27 awards (50% of all awards) with $8.7 million in combined potential value, representing 86% of Sei's total combined potential value across all federal work. The Bureau of Reclamation and Bureau of Ocean Energy Management round out Interior's footprint with three and one award respectively. Across 53 awards spanning 1996 to present, Sei serves only four distinct customer agencies, all within the Department of the Interior.

Activity has flattened significantly in recent years — one award each in 2022, 2023, 2024, and 2025, with two awards in 2026 — reflecting steady-state task-order work under existing IDCs rather than new vehicle or customer acquisition. The vendor holds positions on five single-award Indefinite Delivery Contracts with USGS and related Interior bureaus; the primary active vehicle is Indefinite Delivery Contract 00CRCN0048 (8 task orders, $49 thousand combined potential value) and 140G0224D0008 (3 task orders, $949 thousand combined potential value). Only two awards totaling $554 thousand carry ultimate completion dates within the next twenty-four months, leaving minimal recompete exposure in that window. Sei operates exclusively as a prime contractor with no subcontract relationships in the source data; the vendor's revenue model centers on direct delivery of licensed or procured seismic survey data to federal customers rather than systems integration or subcontracting orchestration.
