Abstract

A method for a pressure release encoding system (1 ) for communicating downhole information through a wellbore (2) to a surface location includes positioning a valve (36) and a brake (44) in a drilling mud circulation system, initiating flow of drilling mud through the system (1 ), sensing flow through the valve (36) and setting the brake (44) at predefined pressure levels, sensing downhole conditions and releasing corresponding percentages of pressure across the valve at time intervals, and determining the downhole conditions at the surface by analyzing those associated time intervals. The method includes activation of the encoding system (1 ) using drilling mud flow and setting predefined pressure levels, so that the pressure drops in the encoding process are from predefined levels at equilibrium and independent of fluid flow.
