INTRODUCTION
Thisreportdocuments the findings of abasicgeochemicalHydrocarbonSourceRock
Characterization Study, carried out on a suite of dried well cuttings collected over the gross well
interval, 500f feet to 16,350feet T.D. in the Shell Oil Company, No. 1 lsleta Central Well, Valencia
County, New Mexico, (Spot NW NW Sec.7; T7N; R2E).
GeoChem received from the New Mexico sample storage center at
On August 19, 1998,
Socorro, six (6)boxes of samples containing driedwell cuttings samples in small brownenvelopes
collected at ten (10f)foot intervalsfrom 500f feet to 16,350feet T.D.
In addition, GeoChem was provided with a full well log from the American Stratigraphic
Company (AMSTRAT) which presented information of formation tops, porosity types, Gamma Ray
and Bore Hole Compensated Soniclog data, a detailed sediment litho percentlog and a supporting
litho description text. This well was assigned the GeoChem Job Number 4416 with each of the
samples selected further identified by a suffix
-001through -053in order of increasingdepth.
The work task designated for this well was authorized by Ms. Nanis Wallace, Burlington
Resources, Farmington. New Mexico,and was to closely follow the programoutlined byGeoChem
1998.
in its budgetary-recommendationletter of August 6,
This program called for the selectionlcompositing and pickinglcleanup
of approximately fif!y
(50) cuttings samples from this well.
Upon starting the sample selection however,
it was noted that thesix (6)boxes of samples
only covered thewell section 500f feet to 13,160ffeet with the section 13.160f feet to 16,350feet
T.D. missing. A check with Socorro indicated that the samples were notat their storage facility but
sincetheAMSTRATlithologwasto
T.D., quiteclearlythe full well profile hadin factbeen
sampled.
Subsequently, Ms. Wallace located the missing samples at the U. S. Geologic Library in
Denver (as part of the AMSTRAT sample donation made to the USGS) and obtained permission
for sampling and analysis. Mr. Randy Laney was contracted to take a totalof thirty-one (31)thirty
(30)footcompositesamples from this well between 13,160f feetand 16,350 feet T.D. These
samples wereof excellent quality.
UsingtheAMSTRAT
litholog informationandourvisualexamination
of the sample
materials from this well, a total
of fifty-three (53)sieved cuttings samples, approximately2-4 grams,
were selected for the geochemical analyses required for this study.
The cuttings sampies were sieved to retain the 20 mesh and greater allowing the fines to
pan through. Each sample was then closelyexamined under a binocular scope aswell as visually
without magnification andhighgradedby the removal of iron(magnet)andreversepicking
of
extraneous mud additive materials. The samples were also air blown in order to remove mica prior
to grinding to passthrough 200 mesh.
The analyticalprogramplannedfor
this well involvedmeasurement of Total Organic
Carbon (TOC) content, Rock-Evai (R-E) pyrolysis, Visual Kerogen assessment of Organic Matter
Type (OMT) and Thermal Alteration Index (TAI) and
Vitrinite Reflectance %Ro determination.

DISCUSSION
The format style of this report isto graphically present the data onwell format figures such
that one can readily assess the various analytically determined hydrocarbon richness and thermal
maturity values for each of the stratigraphic units penetratedby the Shell Oil Company, No. 1 lsleta
Central Well.
Quaternan, and T&hy Sediments f500i to 11.604ifeet)
In Summary Table I andFigures I-A, 1-B,the sample profiling for theQuaternaryand
Tertiarysediments was essentiallyselected in ordertoestablish
an overviewofthepossible

in particular,thethermalmaturitylevelsfortheseupper
sediments.
Thesesectionswerepredominantlycomposedofsands,silts,interfingeredlightgray
claystones, igneous rockfragments and gray and red shale stringers.
Surprisingly, although the total organic carbon (TOC)
values were overall low (average
0.25 and 0.18 respectively;SummaryTable II) the S, volatilehydrocarbonand S, generatable
hydrocarbon values werequite good (S?,
average 690 ppm and 361 ppm; S,,average 718 ppm and
725 ppm). The Hydrogen Index (HI) values were also quite high (Hi, average 293 and 407;01,
average 246 and 222 respectively).
Thesedatasuggesteitherafairlygoodhydrocarbonsourcecharacterforthesesediments
or reflect that these sediments have been infused by migrated out-of-placeoil liquids and possibly
associated gas.
The fact that thecontainedkerogenreflectsonlyamoderatelyimmaturelevel
of
diagenesis (Stage 2- to 2 to 2-to 2. TAI 1.9 to 2.1;Table Iii-A) would seem to favor the migrated
infusion viewpoint. Similarly, calculation of the

Cretaceous Sediments f11.6042 feet to13.264i feet)
The Cretaceous sediments comprise the Cretaceous Undivided section (1 1,604i
feet to
12,414ffeet), the Menefee (12,414ifeet to 13,214ifeet), Point Lookout (13,214ifeet to 13,264i
feet) with the Mancos (13264ffeet to 13650i feet faulted on Permian).
.
These sediments have a good organic carbon content (0.34% to 3.97% averaging from
0.59% to 1.91%) and overall good S, volatile hydrocarbon and S,generatable hydrocarbon values
(average S,,530 ppm to 1,025 ppm; S,, 943 ppm to 2,722 ppm). The thermalmaturityfor the
Cretaceous sediments grades from a moderately immature
generation at 2.4 TAI.
2.0 TAI to a moderately onset of oil
The contained kerogen is dominantly Herbaceous
plant detritus with equal or secondary
amounts of possibly reworked Inertinite. However, varying amounts of more oil-prone AmorphousSapropellicmaterial does enhancetheprospects
for thesesedimentshavingagood
oil and
associated gas source quality.
600i feet of
Excellent quali& bituminous coals appear to be interbedded throughout some
the Menefee (12,450ifeet to 13,214ffeet) and this could reflect an excellent oil and associated
gas generation unit in this exploration area.
.
Interestingly, examination of the visual kerogen profile
across the fault at 13,650f feet
clearly indicates an increase in the geothermal diagenetic (time-temperature) history at this depth
at this well location. This may be a relatively local featureor could have explorationsignificances if
regionally developed.
Perman-aoe Sediments 113.878f feet to 15.680ffeeQ
The Permian-age formations penetrated by this well were San Andreas (13,878ffeet to
13,990ffeet),Glorieta (13,990ffeetto 14,814ffeet),Meseta Bianca (14,814ffeet to 15,056f
feet) and Abo(15.056ffeet to 15,680ffeet).
The Permian sediments overail have a good to very good oil and associated gas source
character at this well location. Total Organic values (TOC) average good to very good (0.93% to
2.25%) along with correspondingly good to very good S,volatile and S, generatable hydrocarbon
contents (S,,340 ppm to 610 ppm. average 350 ppm to 1,190ppm; S,,640 ppm to 4,790ppm,
average 850 ppm to 2,955ppm). Hydrogen Index values and Oxygen Index values again reflect a
mixed oil and gas source facies organic matter type character whichis also indicated by the visual
kerogen organic matter type (OMT) rating (dominantly Herbaceous and
lnertinite with moderate
abundances of oil-prone Amorphous-Sapropel).
The observed maturity level of 2.4 TAI to 2.5 TAI is well into the oil generation window for
these sediments.
Pennsvlvanian-aae Sediments115.680f feet to16.250f feet)
The Pennsylvanian sediments comprise the Madera formation (15,680ffeet to 16,160f
feet) and Sandia formation (16,160ffeet to 16,250ffeet). Limestones become more dominant in
thePennsylvaniansedimentsaccording
to the well logdescription
but thiswasnot
well
represented in the samples provided.
The samples were calcareous but appeared to be more
calcareousshales rather thanlimestones. If thelatter,totalorganiccarbonvalues
(0.27% to
0.97%) wouldrepresentexcellentamounts of organicmatterwhereas, if shales,thesevalues
would rate at a fair organic content.
Theselower
basalsediments

however, do reflecthaving
geothermal diagenetic(time-temperature) history forboth oil liquidsand associated gas generation.
Note the thermal rank (Stage2 to 3-to 2+ to 3-,TAI 2.7 to 2.8)as well as the S, volatile and S,
generatable hydrocarbon contents (S,,
160 ppm to 230 ppm: S,, 350 ppm to 602 ppm: HI, 64 to
101 and 01,129to 133).
These values would indicate that the basal Pennsylvanian sections at this well location
haveamaturefairtopossiblygood
oil andassociatedgas
sourcecharacter which, if more
favorably developed in thickness and organic matter content, along with entrapment of more oilprone Amorphous-Sapropellic kerogen, could constitute an economically significant hydrocarbon
source unit.
Precambrian S&ents
116.250f feet to 16.350feet T.DJ
One (1)sample was taken at 16,240ffeet to 16,270ffeet. This is probably cave from the
Pennsylvanian sediments: however, it did confirm the maturity level at the bottom of this well and
also indicated a possible facies change with significantly higher abundances of more oil-prone
Amorphous-Sapropel and degraded Herbaceous plant detritus (Am-H";Table Ill-A).
