Mass Spectrometer based volatile analysis for
Fluid Inclusion Stratigraphy (FIS)

FIS may be utilized for observing bore hole profiles of fluid chemistry or for delineating reservoir compartmentalization and fluid contacts.

Applications of FIS: Exploration and Production Problems

* migration pathway detection
* time-integrated seal distribution and characterization
* identification of dry holes which are proximal to undiscovered petroleum
* pay/bypassed pay delineation
* product type prediction and product risk assessment
* pressure compartment delineation
* fault tracing
* identification of reservoir compartmentalization and connectivity
* petroleum-water transition zone characterization


FIS generally follows two main lines of investigation:
A) A mass spectrometer analysis of volatiles present.
B) Fluid inclusion analysis , which includes petrography and microthermometry to assess temperatures, salinity and oil properties including API gravity.

What are Fluid Inclusions

Fluid inclusions are microscopic traces of past or present-day subsurface fluids that become entrapped in rocks during formation of diagenetic cements or healed microfractures. These fluids are generally faithful recorders of pore fluid chemistry and are not subject to evaporation or loss of light during sample storage, and/or sample preparation, handling ect.

They persist in the geologic record long after the parent fluids have moved on, and are continuously formed even up to the very recent past. Fluid inclusions can be detected, characterized and quantified to variable degrees with sophisticated instrumentation such as mass spectrometers, or by preparing thin sections of rock material and viewing them under a microscope equipped with a controllable temperature stage. Specific tests can be done on these inclusions in order to study processes occuring within the earth, in particular, processes involving migration and accumulation of oil and gas.

What is Fluid Inclusion Stratigraphy

Fluid Inclusion Stratigraphy (FIS) is a patented Amoco technology, licensed to FIT Inc., which provides a means of analyzing organic and inorganic fluid species within fluid inclusions trapped in cuttings, core or outcrop samples. The newly available technology delivers a unique view of petroleum and diagenetic processes operating from basin to reservoir scale.

Our automated analytical system employs a novel, quadrupole mass spectrometer configuration that allows rapid chemical characterization of inclusion volatiles. This information is used to predict the distribution of oil and gas within the subsurface, to characterize specific aspects of undiscovered petroleum that affect the economics of producing the petroleum, and to provide information on when (if at all) petroleum may have moved through a given portion of the subsurface.

Large sample sets from single or multiple wells can be evaluated, allowing analysis of fluid inclusions in both archived samples (cuttings or core), and currently drilling wells to play a key and cost-effective role in evaluation of exploration acreage and focusing of exploration efforts on the most prospective areas. These technologies are applicable to virtually every geological environment, lithology, and petroleum type. FIT's interpretive expertise is based on experience analyzing over 750,000 samples from more than 2500 wells encompassing every major petroleum-producing enviroment. Over the last 8 years FIS has found significant petroleum reserves, influenced exploration and acreage decisions and provided innovative options for resource estimations, petroleum and enhanced oil recovery operations.

Common Questions about Fluid Inclusion Stratigraphy

1) What is the amount of each sample that you require for analysis?
We analyze about 0.25-0.5 gram, but we suggest that you send about 1-2 grams of material for each sample.

2) Can the samples be from core as well as drilling cuttings?
Core and cuttings work equally well. Generally cores are sampled about 0.5 m and cuttings at 3-10 m depending on how often the cuttings were caught. The core analysis has the potential to provide very detailed information at the reservoir scale. You can mix core and cutting samples from the same well under the same pricing scheme.

3) Is 10 to 20 samples from a specific interval enough to obtain a reasonable answer, or should entire wells be analyzed?
We recommend analyzing as much of the section as you can afford, because it always seems to provide some useful and unexpected information, as well as allowing establishment of background readings outside the main zone of interest. 10-20 samples is a pretty small sample set; we could arrange to work with that few of samples, but it would be better if you analyzed 180 samples from the same well.

4) Does an interpretation of the raw data come with each sample?
Analysis includes interpretation of both the FIS data and thin sections that we prepare as part of the basic FIS service. Additionally, we will add electric log suites if you provide them in LAS format. This is good for comparing log responses with FIS data directly in the report.

5) Aside from cost and time, how does this type of fluid inclusion analysis compare to other methods of analysis (i.e. heating a sample of rock and observing when the fluid inclusions disappear)? Is it accurate?
The FIS technique is designed for looking at the geometry of fluid distribution (both present and past) in the context of exploration or production. Traditional, microscope methods of studying fluid inclusions are irreplaceable, give complementary information, and we highly recommend them. Mostly however, they address a different set of questions. For example, temperature history, thermal maturity, salinity, bubble point / dew point, and API gravity. They do not provide larger scale information about detailed fluid distribution or chemistry.

6) What is the cost per sample?

We offer a well stratigraphic evaluation based on the presence or absence of key elements. With this in mind we have two price schedules; one based on 180 samples, and one based on 575 samples. We really need to see as many samples as possible to utilize FIS to it's full potential.
