Sterling tools: All have the same OD for ease of making up or breaking down.  Tools are hard banded to safely set in slips.

  Centrifuges:  Accurately obtain percentages of fluids.        

  RW Meters:  Measure salinity to determine if water is filtrate or formation.  

  Hydrometers:  Measure gravity of oil.    

  Surface equipment:  Checks to 2500# for safety during large volume tests.                                        

  Electronic Memory Recorder:  Designed for extreme precision and reliability in harsh downhole environments.  Pressure range: 5000psi.

  Electronic Micro Gauge (WMG-PR):  Incorporates the latest sensor technology to improve transient response through continuous compensation of temperature.  Pressure range: 5000psi.

  Laptop computers:  The data can be downloaded and viewed immediately.  The data can also be sent via modem to our Hays office and then sent on to the Operating company via e-mail or fax. 

  AK1 Mechanical Recorder

  ATMS2000 software:  View and manipulate data gathered on the DST.  Produces Horner plots and derivative curves.
