MASS SPEC CHEMICAL PROFILING (WITH BACK-UP)

Announcing the New dq1000™ Wellsite Gas Analyzer*. . .FIT's new dq1000™ "Divining Quad™" is a revolutionary new concept in Wellsite Geochemistry and the first commercially available

implementation of Mass Spectrometry for on-site, real-time formation fluid analysis and evaluation. Conceptually, the dq1000™ is similar toconventional equipment (i.e., hot-wire + GC), in that it continuously analyzes volatiles extracted from the drilling mud and correlates them withdepth. But here the similarity ends. At the heart of the dq1000™ is a quadrupole mass analyzer which, in addition to performing the usualTotal Gas + C1-nC5 analysis, is capable of detecting C6-C13 hydrocarbons (i.e., hexane, heptane, octane, etc.); distinguishing among paraffins,naphthenes and aromatics; and monitoring a variety of water-soluble species such as acetic acid, toluene and benzene, and inorganicsincluding hydrogen, helium, nitrogen, carbon dioxide, oxygen, argon and sulfur-bearing compounds. Correlation of these geochemicalindicators with available drilling parameters and lithologic data allow real-time evaluation of Pay, Wetness (e.g., Pixler Ratios), Petroleum Typeand Quality, Reservoir Compartmentalization, Fluid Contacts, Seals, etc.

The Divining Quad™ is a portable, fully-automatic, stand-alone analyzer. Its modest size, weight and electrical requirements facilitatedeployment in even the most restrictive environments. Sensor inputs on the dq1000™ monitor penetration, circulation, and pump strokes(any of which can also be read from a WITS-enabled local network) to derive Depth, ROP and Lag for the preparation of geochemical logs. While drilling, analytical results may be viewed on-screen locally or remotely and are always available for immediate LAS import into commercially available graphics packages. Bi-directional communication can be enabled over both LAN and the Internet.

The Divining Quad™ is user friendly requiring minimal instruction for setup, operation and routine maintenance. In field trials, the system has produced continuous, high quality data with minimal operator intervention for months at a time. Unlike FID detectors used in other gas analyzers, no auxiliary gases are needed thereby reducing costs and safety concerns. Mass Spec Analysis eliminates HC/CO2 interference - a common problem with many detectors leading to serious underestimation of hydrocarbons in some cases. The dq1000™ accurately distinguishes mud gas from atmosphere allowing automated (and remote) monitoring of gas trap/extraction line performance. Optional two port operation allows evaluation of hydrocarbon recirculation and potential mud additive interference.
