The need for good quality measurement has increased dramatically in recent years. Deregulation of market pricing structures, open access markets, increased exploration and drilling costs, fierce competition and new regulatory requirements have all influenced today’s approach to quality measurement methodologies. In fact, the terminology has evolved from “gas volume measurement” to “total energy measurement.” Today, not only is the volume of gas a consideration, but also the quantity of energy the gas produces. The gas industry has evolved from the MMcf to the MMBtu.

Opportunities For Offshore Oil And Gas Contracting

It is estimated by Barclay’s Capital in a recent industry survey that nearly $600 billion will be spent by oil and gas exploration and production companies in 2012 (an increase of 10% over 2011). One reason is that the oil industry is mature which is reflected by the rising costs. From 1995-2004, $2.4 trillion of capital expenditure resulted in an increase of global oil production of 12.3 MMbpd; in the following six years, 2005-2010, despite the same spend oil production fell by 0.2 MMbpd.
