Eleven companies from Norway and the UK collaborated on testing of drill stem test (DST) tools under high pressure and high temperature conditions. The petroleum companies and equipment suppliers found that the tools, which determine the viability of potential oil fields, can sustain operations if planning is adequate and suitable drilling mud is used. The tools successfully operated for three days under simulated conditions of 15,000 pounds per square inch of pressure and 410 degrees Farenheit., A joint-industry project set up procedures and full scale tests to determine the reliability and integrity of drill stem test (DST) tools for use in difficult high pressure, high temperature [...]

Corrosion inhibitors should be tested by electrochemical methods rather than gravimetric, which may have a high error range. An experiment measured weight loss of pipeline inhibitors and downhole inhibitors to check the accuracy of continuous wheel gravimetric ratings. Because a percentage of protection originally stated as 92% may be reduced to 89% or augmented to 97%, the comparison of corrosion inhibitors becomes difficult to quantify., Tests indicate that ranking of corrosion inhibitors by the percent of protection may be incorrect. Other conditions need to be considered because the low weight loss of a high percent [...]

Research into sea bed drilling will look into the capability of coiled tubing drilling. Industry experts are concerned further development of current drilling equipment will not reduce costs. The CMPT support further work on sea bed-based coiled tubing drilling which should eventually lead to the introduction of the more efficient Depth Independent Drilling System. Deepwater drilling is very expensive, with most rigs in constant use and day rates for rigs increasing by more than 150%, since 1996. The rising cost of rigs have resulted in the industry having to pay an additional $4 billion.

The Oil Spill Prevention and Response Advisory Group selected a concept for a well-capping device for use in British offshore oil and gas operations. The concepts were designed by Wood Group Kenny and could take 11 months to manufacture.
