Pore fluid pressure at DSDP Leg 84 Holes
Listed in PANGAEA
Evidence of considerable overpressuring of pore fluids in the sediment drilled during Leg 84 was obtained from direct measurement of pressure by two methods.
Description
The first involved measurement of back pressure when the annulus of the drill hole became constricted with unremoved drill cuttings or constriction was caused by plastic inflow of the drill hole walls. The second involved measurement of pressure ahead of the bit in conjunction with in situ water samples and heat flow.
All measurements indicated abnormally high pore pressure even in slope deposits of the Middle America Trench off Guatemala.
