Acoustical coupling is proposed as a means of determining the presence and acoustical impedance if materials behind casing in cementation evaluation. Expressions for computing coupling and attenuation in multi-receiver/transmitter logging systems are analyzed in an exponential model for the spatial decay of elastic wave energy propagating axially along the casing. Amplitude change between transmit...

PURPOSE:To automatically produce an objective program including vector instructions efficiently for multiplex loop operations, by separating a condition equation section of a program statement from an operation section to be controlled and generating a specific instruction to each of them. CONSTITUTION:The relation of a program statement in a loop for control is analyzed in an electronic computer ...

A subterranean zone penetrated by a well bore is cemented with a retarded, high temperature non-thinning, cement composition which contains a delayed viscosifying agent which is a galactomannan gum which has been depolymerized and treated with a complexing agent whereby the hydration rate of said depolymerized gum is retarded at temperatures below 120 DEG F to 140 DEG F (49 DEG to 60 DEG C) and a...

A control signalling arrangement for a pulse transmission system uses a main data stream including a block parity channel. Control signals are transmitted from an end terminal to a repeater by inserting the control signals in periodically spaced bit positions of the block parity channel. At the repeater, the control signals are separated from the block parity channel for controlling the circuits o...
