Benefits of technology

The invention is a barge designed to develop natural gas assets in fields that are too small to support an LNG facility. The barge includes a syngas generating section and a Fischer-Tropsch reaction section. It is transported to the gas formation by lift ship or other dry haul method and can also undergo product upgrading. The technical effect of this invention is that it allows for the efficient development of small gas fields without the need for an LNG facility.

Problems solved by technology

Excess reserves may be considered stranded where a paltry delivery rate is required to avoid oversupply of local markets.
Negative economics may also arise from technical complexity or expense associated with recovering and / or gathering the gas.
Stranded natural gas may be used as a raw feedstock for GTL operations, thereby monetizing otherwise worthless gas.

Embodiment Construction

[0008] The transportable GTL inland barge enables an exploration and production company to produce and thus monetize stranded gas fields. The GTL barge focuses on gas reserves in or near shallow water or onshore gas reserves that are near the coastline or other navigable waterway.

[0009] The GTL barge is ideally suited to process associated rich gas that might otherwise be flared or re-injected. Estimated worldwide flared gas is about 10 billion ft3 per day. A single GTL barge, for example, may be designed to produce approximately 20,000 barrels per day (bpd) of total liquid products, including approximately 12,000 bpd of GTL products. Assuming the natural gas has about 2 gpm propane and higher carbon number natural gas liquid (“NGL”); the combined NGL and GTL products are about 8700 bpd of clean diesel fuel, 7300 bpd of naphtha, and 4400 bpd of LPG. The mobility and / or transportability of a GTL plant enables the operator to mitigate long-term project and financial risk by having th...

Abstract

A transportable GTL processing facility constructed on an inland barge is provided. Also provided is a process for producing liquid hydrocarbons from natural gas utilizing a transportable GTL processing facility. The facility and process may be used to access and convert stranded natural gas in an economical fashion into liquid hydrocarbons. Further provided is a transportable GTL processing facility and process for producing liquid hydrocarbons wherein the liquid hydrocarbons are upgraded into transportation fuels and other locally usable materials.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to Provisional Application Ser. No. 60 / 557,638, filed on Mar. 30, 2004.FEDERALLY SPONSORED RESEARCH [0002] Not applicable REFERENCE TO MICROFICHE APPENDIX [0003] Not applicable. FIELD OF THE INVENTION [0004] This invention relates to gas-to-liquid (GTL) technology, and more particularly to GTL processes practiced on a mobile or transportable platform. The invention further relates to a transportable GTL facility which is capable of accessing stranded gas reserves. BACKGROUND [0005] Of the estimated 5,500 TCF of natural gas reserves worldwide, nearly one-half is stranded, with over 50% of those reserves being offshore. For our purpose, the term “stranded gas” means natural gas that cannot be economically delivered to market using current gas transportation methods or current commercial GTL processes. Stranded gas includes associated and flared / vented gas, and gas that is re-injected purely for regulatory ...
