When porosity of gas hydrate reservoir is less than 5%, gas hydrate saturation is greater than 70%, occurrence scale is less than 50 m, or bury depth is greater than 500 m, AMT technique cannot identify and delineate the favorable gas hydrate reservoir. Survey line should be more than ...
The transport of gas-condensate mixtures of various compositions has been found to be accompanied by a slight increase in viscosity in the coldest period when ground temperatures at depth of a condensate pipeline reach −4 to 0°C (25 to 32°F). The decrease in the temperature of reservoir...
Natural gas from a pressured lease line is the least expensive drilling fluid gas. In some cases, there may be objections to the irregular use of gas from the line. This has to be locally determined. The safety aspects of using gas are much easier to predict and control than with the us...
Based on the formation mechanism of mud volcanoes, such as on Academician Ridge66, hydrate-bound gases are microbially produced in relatively shallow layers, that is, from the lake bottom to a depth of 300–400 m, where the maximum temperature is approximately 40 °C. The sedimentary...

(a) Valence-band spectra measured at 500 °C in 0.3 Torr H2/H2O/Ar using a 250-eV photon energy. Information depth is ~0.6 nm. The Ce 4f peak (labelled) directly corresponds to the Ce3+concentration because of normalization by the total Ce intensity. (b) Ce 4d core level ...
zone (HSZ).We construct a series of 1D and 2D models of the Hikurangi Margin along a depth-converted 2D-seismic line south-east of the North Island of New Zealand(Plaza-Faverola et al.,2012;Figs. 1;2)using PetroMod™v.2012 petroleum systems modelling software provided by Schlumberger....
Oh, I’m really generous with my time and wisdom and I’m usually quite friendly, sociable, and approachable (unless a line has been crossed!). That’d do it! LOL – Also see Sagittarius on the 11th, with Jupiter Libra in the 9th. You’re not the only one in my world — there ...
(5) drilled passages 117. As the water level increases, the static pressure at the outer diameter increases with respect to the center line pressure due to increased depth and due to increased rotational velocity resulting from greater contact area on the rotating on the edges 62 of disks 44....
The operator may verify the total well length by either the tape measure method or the video camera method, or other methods known to those skilled in the art. To determine the starting depth, the operator subtracts the screen length from the total well length. Starting depth may also be ...
