Data

 

The logging data was recorded by Schlumberger in DLIS format. Data were reviewed and formatted for the online database at the Borehole Research Group of the Lamont-Doherty Earth Observatory in May 2015.

The NYSTA Tandem Lot #1 geologic characterization well was drilled by TriCarb Consortium for Carbon Sequestration (www.tricarb.org <http://www.tricarb.org> ) in 2011. Located by Exit 14 on New York State Thruway in Rockland County, the well is 6,885 ft deep. It transects Triassic terrestrial sediments of the Newark Rift Basin and the Palisade diabase sill (at the depths of ~5,000-6,550 ft). Most of the well was drilled without coring, but a single core section was collected at 4,570-4,880 ft in the sediments above the Palisade sill. The well was initially drilled to a depth of 1,506 ft, of which the upper 602 ft were cased. Logging was carried out with a variety of logging tools (see table) both before and after coring. The hole was subsequently cased to 1496 ft and then deepened to a depth of 6,885 ft. Logging operations followed (see table) as well as testing of the formation fluid using the Modular Formation Dynamics Tester. After the completion of drilling and logging operations the well was plugged, and the site restored to its original condition.

The depths in the table are referred to the rig floor, which stands 16 ft above ground level. The data presented online is the original data, with out any depth-matching performed between runs.

 

SAMPLING RATE. The data is generally sampled every 0.5 ft. The following tools also provide high-resolution data:

AIT (resistivity): 3 inches

EDTC (gamma ray): 2 inches

HGNS (gamma ray and porosity): 2 inches

FMI: 0.1 inches.

ACOUSTIC DATA. The Sonic Scanner (MAPC-MAXS) recorded compressional, shear and Stoneley wave data.

GEOCHEMICAL DATA. The Elemental Capture Sonde (ECS) collected data in both capture and inelastic modes. In the upper part of the hole (Run 1B) only the elemental yields from the 20 Elemental Standards Processing are available. In addition to these, in the lower part of the hole (Run 2C) the dry weight fractions of the elements were calculated by Schlumbergere using the SpectroLith WALK2 Model as well as the dry weight fractions of the main minerals.

QUALITY CONTROL

Gamma ray logs recorded through casing should be used only qualitatively, because of the attenuation of the incoming signal.

A wide (>12") and/or irregular borehole affects most recordings, particularly those that require eccentralization and a good contact with the borehole wall (porosity, density).

Hole diameter was recorded by the Powered Positioning Device and Caliper tool (PPC) and by the FMI tool (C1 and C2). Due to a bug in the GeoFrame software we were unable to create ASCII files of the FMI caliper. In the upper part (down to 1496 ft) the hole is very smooth and in gauge, with caliper readings just below 13 inches (the drill bit used was 12.25 in). Below 1500 ft the caliper shows only a few smooth intervals (1500-2000 ft, 3405-3610, 4600-5000 ft, 5160-5390 ft). In the remainder of the hole, which was drilled with a 8.5 inch drill bit, is often rugged, with enlargements up to 14 inches.

 

A null value of -999.25 may replace invalid log values.
