The APR DST Tools is a sort of well testing downhole tools which is operated by the annulus pressure.
Drill stem Testing Tools are applied for oil and gas well testing formations after casing has been set in a well. Drill Stem Tests in holes combined with measurement of the production rate,pressure and temperature.
The drill stem testing tools are made of alloy steel and Inconel steel, which make the DST tools used in full H2S service with high pressure and high teperature working condition. The APR DST Tools are applicable for 4 1/2” to 20” casing, the tools OD is 3 7/8” and 5”, Working pressure upto 105Mpa, working temperature upto 425F.
The APR drill stem testing tools are able to be operated in offshore operations and on land operations where wells are deep and highly deviated.
Features of APR DST Tools
