Description

The core material that will substantiate the workshop is from three behind-the-outcrop wells. These

were drilled in the frame of a research agreement between ExxonMobil and Universitat de

Barcelona. Two of the wells are located in the Solitary Channel Complex (Miocene, Tabernas

Basin). One represents a channel axis position, the other was drilled nearby in an off-axis position.

The third well was drilled in the O Grao turbidite system (Eocene, Ainsa basin) in a stack made up

of channel, channel-lobe transition, and lobe elements. The dataset from these three wells is made

up of more than 200 m of continuous core (with excellent RQD and 99% core recovery) wellbore

images, some wireline logs, and CTscan data and linescan images of the entire core all depth

matched and correlated to outcrop. The workshop will be mostly based on linescan core images of

halfcore.

Starting from conventional core descriptions of a representative selection, the workshop will

develop into depositional interpretation and architectural evolution, ending up into a wellcorrelation

exercise. The results will be compared to outcrop (conventional and digital) and to a

broader scale stratigraphy as captured by a 3D geocellular facies model.

There will be time allowed for core descriptions by groups of participants, and time to structured

debate on the interpretations, and final work and debate oriented to the identification and meaning

of the similitudes and differences between the two locations.

This workshop will make use of core images and large-scale core photos with participants using these to analyze the core sections and have lively discussions about various interpretations.

This workshop is limited to 26 participants.
