Alaska North Slope(ANS) permafrost zone is rich in hydrate resource, where is one of the specified targets for hydrate R&D in USA. The PCB and PCS pressure core samplers for NGH in USA have been respectively developed and applied in DSDP、 ODP、 IODP and ANS since 1970’s. Hot Ice #1 well, the first dedicated hydrate research well in Alaska, was completed in early 2004. Newly developed Arctic Drilling Platform, Mobile Core Lab, Smart Drilling etc. were successful deploied in the research well despite of missing the hydrate layer. Mt. Elbert #1 research well was smoothly drilled(to 914m), cored(recovery 85%), logged and downhole pressure tested with MDS in February 2007. This science program successfully achieved all of its objectives. Naturally occurring geohazards and “Industrial” gas hydraterelated geohazards were studied, the latter can be categorized mainly as follows: Drilling through GH, Producing through GH and Producing from GHgeohazards. The theoretical and lab studied of NGH , especially for hydrate production with CO2-CH4 exchange technology, have been effectively executed for decades by many academic centers and universities in USA. In May, 2012, ConocoPhillips, in a cooperative effort with the JOGMEC and the U.S. DOE, successfully completed Ignik Sikumi #1 well gas hydrate production test using CO2-CH4 exchange method in ANS. Overall, the well produced for 30 days during the 38-day flowback period, with cumulative gas production approaching one million scf (28317m3). The test result shows that CO2-CH4 exchange for NGH production is one of the most important and effective methods, which can greatly mitigate environmental pollution and damage.
