Interaction Between Shale and Water-Based Drilling Fluids: laboratory Exposure Tests Give New Insight Into mechanisms and Field Consequences of KCI Contents

摘要

on in a subsea annulus is presented. A discussion of some important formation fracturing aspects is presented. The necessary equipment is described. This includes a description of the modified well head deisng for cuttings re-injection and description of a flexible hose transporting the re-injection slurry from the platform to the wellhead. A short description of the cuttings re-injection operation is given where cuttings were re-injected into the same well as being drilled.#p.207-214#wql## 7?tin capabilities(below 300 #mu#m) of ultrasoundwithvarious rock lithologies, different solids fluid loadings and the length of exposure time to the sonic waves. Secondly it showed that a stable slurry can be maintained enabling drill cuttings to be handled and transported to other disposal sites (onshore or offshore, legislation permitting) in suspension. This enw approach compared to handling dry cuttings unlocks new opportunities with regrads to cuttings re-injection and creates new dimensions for handling and transportation drill cuttings.#p.199-205#wql##??All measurement use bucking currents returning to the tool rather than to surface, efectively eliminating the Groningen and dril
