Geographically surrounded by Russia to the north, India in the south, Central China to the east and the Caspian Sea to the west, Central Asia has made strides in recent years to exploit its fossil-fuel resources following the dissolution of the Soviet Union. The ex-Soviet republics of Central Asia, specifically Azerbaijan, Kazakhstan and Turkmenistan, boast plentiful oil and gas reserves, and the offshore Caspian region is the primary energy hub for these countries' burgeoning exploration and production operations.
MWD/LWD refer to measurement and logging while drilling. The MWD operator measures the path of the wellbore while it is being drilled, and this data is then used to help plan the direction that the well will be drilled. LWD, while sometimes used interchangeably with MWD, refers more to the process of obtaining information about the rock being drilled, while MWD is more about the drilling operation.
