6 Drill stem incorporate sophisticated electronic devices that sense,
transmit, and record formation characteristics as the bit drills ahead.
7 The expanded packer depressurizes the hole above the packer.
8 The DST crew analyzes the downhole pressures which indicate whether
the well can produce.
9 A core sample is ordered when the operator wishes to examine directly
a formation sample that is larger than the cuttings.
10 The core is often several feet (or metres) in diameter and several inches
(or millimetres) long.

7 Fill in the gaps.

a) formation c) presence e) radio g) portable i) tool

The tools transmit the_____ (1) they gather to the truck or logging shack.
There, special recorders and computers store the information. For on-site evaluation,
computers in the _____ (2) laboratory print the data (fig. 178). These logs give the
operator a first look at what a _____ (3) may yield. For thorough evaluation, the
portable lab can transmit the log's data to powerful computers located at central
processing _____ (4). By carefully examining well logs, the operator can determine
whether to complete the well. Well logs not only indicate the_____ (5) of oil and gas,
they also indicate how much may be there.
During _____ (6), the operator can run logging while drilling (LWD) tools in
the drill stem. These instruments incorporate sophisticated electronic _____ (7) that
sense, transmit, and record formation characteristics as the bit drills ahead. The LWD
_____ (8) transmits formation information on a pulse the tool creates in the drilling
mud. Much as_____ (9) waves transmit sound information through air, mud pulses
transmit formation information to computers on the surface. The computers
_____ (10) and display the information in readouts that experts on the site can
interpret and evaluate.

8 Scan the text and correct spelling and grammar mistakes.
During driling, the operator can run logging while drilling tools in the drill
stem. These instruments incorporate sophisticated electronic devices that sense,
transmit, and record formation characteristics as the bit drills head. The LWD tool
transmitts formation information on a pulse the tool creates in the drilling mud. Much
as radio waves transmit sound information through air, so mud pulses transmit
formation information to computers on the surface. The computers analyse and
display the information in readouts that experts on the site can interpret and evaluate.
