Regional Expertise

Mexico: We have extensive experience of Mexican carbonate

reservoirs and petroleum systems gained over a number of

exploration and reservoir-based projects. Please contact us ifyou would like to learn more about the complex geology and

hydrocarbon potential of Mexico.

Southern Atlantic margins:we have worked on pre- and post-

salt carbonate systems on both sides of the Atlantic. We

are undertaking a comprehensive study of the microfacies of

Brazilian pre-salt carbonates and a comparative study of pre-salt

carbonates from Africa. We have also looked at post-salt mixed

carbonateclastic lacustrine and continental margin systems fromAfrica.

Arabian Gulf:we have undertaken regional exploration and

detailed reservoir description projects on reservoirs ranging in age

from pre-Cambrian to Tertiary from Kuwait, Qatar, UAE and Oman.

Circum-Mediterranean:projects include description of fractured

and karsted reservoirs, field work on karst and resedimented

carbonates southern (Italy). Field mapping and logging of

Cretaceous and Tertiary carbonates in western Greece. Blockevaluation, reservoir modelling and regional studies on Libya.

Reservoir description and modelling and exploration projects in

Syria.

Diagenetic Studies

Cambridge Carbonates offer expertise in

carbonate diagenesis, plus the description andinterpretation of microfacies.

We produce diagenetic models which provide

key results such as timing of fluid flow and

evolution of reservoir properties throughout the

entire diagenesis. Resultant diagenetic models

are useful to optimise the understanding of rock-

types.To achieve these studies, we follow a well

defined workflow integrating:

Macroscopic qualitative and quantitative

observations (cores and/or outcrops)

Microscopic qualitative and quantitative

investigations (observations on stained thinsections, cathodoluminescence, SEM)

Geochemistry (stable C & O isotopes,

Sr isotopes, trace/major elements) and

thermometry (fluid inclusion analysis).

Keeping in mind the constraint provided by the

sequence stratigraphic framework and burial

history.

6. Production of parageneticsequences: based on the

findings from 1-5.

7. Burial history and sequence

stratigraphy integration -

provide crucial constraints

for placing the paragenetic

sequence into a reservoir/basin

history.

Understanding Porosity Systems

Cambridge Carbonates

have developedinnovative techniques

that characterise micro-

to macroscale pore

systems by image

analysis, thus helping

you to understand the

links between porosity

and permeability incarbonate reservoirs.

Carbonates Sequence Stratigraphy

Carbonate sequence stratigraphic

analysis allows better understandingof reservoir layering and the

geometry of flow units. This

fundamental service is performed

in conjunction with seismic

stratigraphy, biostratigraphy and

microfacies analysis.

We have extensive experience of

undertaking field-wide studies usinglog-defined facies and sequence

stratigraphic schemes, from which

detailed models can be built and

used as input into simulation

models.


14/16


Reservoir Characterisation

We can develop reservoir models by integrating core, poroperm data,

logs, seismic, well test and production data to define flow units. Thesecan be used in volumetric determination and future planning.

Think of us when you

are:

Considering the

re-activation of an

abandoned carbonatefield.

Planning to exploit

an underdeveloped

carbonate reservoir.

Reviewing a new

asset or thinking

about acquiringan asset to which

carbonates and/

or evaporites are

important.
