The ICS-X1-ST1 well was a sidetrack of the ICS-X1 well to reach the Huamampampa Formation target. The sidetrack encountered the Huamampampa Formation at 4905m and drilled to 5600m total depth. Between 4905-5376m, 471m of quartzitic sandstone and siltstone of the Huamampampa Formation was found, which was very faulted and fractured. A drill stem test between 4905-5150m produced over 1000 thousand cubic meters per day of gas and condensate. The well provided data on the stratigraphy and structure of the Huamampampa Formation in the area.

A comprehensive review on passive heat transfer enhancementsMohamed Fadl
Enhancing heat transfer surface are used in many engineering applications such as heat exchanger, air
conditioning, chemical reactor and refrigeration systems, hence many techniques have been investi-
gated on enhancement of heat transfer rate and decrease the size and cost of the involving equipment
especially in heat exchangers. One of the most important techniques used are passive heat transfer
technique. These techniques when adopted in Heat exchanger proved that the overall thermal
performance improved significantly. This paper reviews experimental and numerical works taken by
researchers on this technique since 2004 such as twisted tape, wire coil, swirl flow generator, y etc. to
enhance the thermal efficiency in heat exchangers and useful to designers implementing passive
augmentation techniques in heat exchange. The authors found that variously developed twisted tape
inserts are popular researched and used to strengthen the heat transfer efficiency for heat exchangers.
The other techniques used for specific work environments are studied in this paper. Twisted tape
inserts perform better in laminar flow than turbulent flow. However, the other several passive
techniques such as ribs, conical nozzle, and conical ring, etc. are generally more efficient in the
turbulent flow than in the laminar flow.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

ICS-X1-ST1 GWR 8
1.1. General Summary
1.1.1. General setting
The foothills of Southern Bolivia and Northwestern Argentina are characterized by a succession of sub-parallel
NNW-SSE trending mountain ranges. Each of these ranges corresponds to a tightly folded elongated anticline
structure up to 300km long. The crest of these mountain ranges have an elevation of 1300-2000m while the
synclines separating the mountain ranges have a relief of 600 to 800m.
The Ipati block is located in the Cordillera Province of the Santa Cruz department. The area corresponds to a
morphological unit of the southwestern part of the foothills. Steep ranges cut by rivers running eastwards
characterize this area.
1.1.2. Regional Stratigraphy
Within the South Bolivian foothills, the undeformed stratigraphic section is approximately 10,000 to 12,000 meters
thick, ranging from Silurian to Tertiary (Pliocene). This section consists almost exclusively of clastics with only minor
carbonates and evaporites present.
The stratigraphic section can be separated into three main cycles : Cordilleran, Subandean, and Andean.
During the Cordilleran cycle, of Silurian to Devonian age, 3500m of near shore to shelf, marine clastics units were
deposited. The Devonian section contains the main source rock (Los Monos Shales) and the main reservoirs
(Huamampampa & Santa Rosa Formations) of the area.
The Carboniferous to Triassic section of the Subandean cycle lies unconformably on the Devonian.
The Carboniferous section (1000 to 1500m) is dominated by massive continental sandstones, with good reservoir
quality (Escarpment, Chorro and Tupambi Formations) and peri-glacial diamectites (Taiguati and Tarija Formations).
The Permo-Triassic section (400m) contains very good fluvial and deltaic sandstones (Cangapi Formation) and
silicified carbonates (cherts of Vitiacua Formation).
The Andean cycle is composed of a thick section of Tertiari foreland deposits (up to 6000m) (Chaco group :
Guandacay, Tariquia and Petaca Formations) and fluvial to eolian sandstones of probable Jurassic to Cretaceous
ages with very good reservoir characteristics (Tacuru group : Ichoa Formation).
Due to the large scale of tectonic activity during the later part of the Andean cycle, all the good Tertiary to
Carboniferous reservoirs outcrop at surface.
1.1.3. Exploration History
On the Incahuasi trend three wells have been drilled in the proximity of the well. These wells recognized only the
Carboniferous and the Upper Devonian.
Aquio-X1, drilled in 1962-1963 by YPBF, is located 4km NNW of ICS-X1 and reached a TD of 2209m in the Los
Monos Formation.
Lagunillas-X1 (LGN-X1), drilled by YPBF in 1964, is located 23km to the North and reached a TD of 1817m in the
Jurassic (Tacuru Group).
La Montana-X1001 (LMT-X1001) (drilled in 2000 by Tecpetrol), located 9km to the South, on the same trend,
reached a TD of 2754m in the Iquiri Formation.
On the neighboring trends, the following wells reached the Humampampa Formation:
- Camiri-201 (CAM-201), drilled between 1962 and 1964, is located 28km to the SE. It reached a total depth
of 3677m in the HMP.
9. TE&PB INCAHUASI-X1-ST1 ICS-X1-ST1
ICS-X1-ST1 GWR 9
- Tatarenda-X27 (TTR-X27) was drilled in 1967 by YPBF. It is located 80km to the NNE and reached a TD of
3030m in the HMP.
- Inau-X2, drilled in 1988-1989 by YPBF, is located 20km to the SW. It reached a TD of 2768m in the HMP.
- Cumandairenda-X1, drilled in 1994-1995 by YPBF on the same trend than Inau-X2, is located 47km to the
SSE. It reached a TD of 3733m in the HMP.
All these wells were dry, except Inau-X2 and Lagunillas-X1. In Inau-X2, 5.5m thick gas-bearing sands were
encountered in the Los Monos section. Nevertheless logs and DST performed show these levels of poor reservoir
characteristics and marginal production (0.282 MMCFD). In Lagunillas-X1, gas with low pressure was tested in a 6m
thick Iquiri sandstone.
1.1.4. Objectives
Well ICS-X1 was drilled deviated to the West from a surface location on the eastern flank of the Incahuasi surface
anticline (SP 2097 of line T03-IP01). The objective was to reach the expected top of Huamampampa Sandstone at
2950mss. After drilling an unexpected reversed flank of the anticline, it was stopped at 5187mMD in a formation
interpreted as the carboniferous Tupambi formation, dipping around 70° toward the East.
Based on this new information, the structural model was reviewed and indicated that the top HMP could be located
eastward to the TD of ICS-X1, almost at the vertical of the surface location.
It was then decide to side track the well (ICS-X1 ST1) in order to reach this new target.
The main objective of the Incahuasi-X1 ST1 well corresponds to the same tight, fractured Devonian sandstones of
the Huamampampa Formation.
1.1.5. Main Results
The well ICS-X1-ST1 encountered the Huamampampa Fm at 4905m (-3352mTVDSS) and was drilled down to
5600mRT (-4019mTVDSS).
A total of 471m of quartzitic Sandstone and hard Siltstone was found (from 4905 to 5376mMD):
• From 4905 to 5246mMD: dipping 50 to 80ºW,
• From 5246 to 5370mMD: dipping alternatively 45°E to 80°W
• From 5370 to 5376mMD, and then in Shale to 5600mMD (TD): dipping 40 to 60°E.
This formation was very faulted and fractured, and represents 252m of true thickness. Below 5376mMD to TD, only
very radioactive shale was found. A total of 329m (true thickness) of HMP Formation were thus investigated.
A bare foot DST was performed between 4905 to 5150mMD; it produced 1093ksm3/d of gas and 119m3/m3 of
condensate with a 44/64” choke.

3.1. Mud Logging General Data
The Geoservices mud logging ALS 2.5 unit arrived on location on 02 October 2003 and the well was spudded on 6-
10-2003.It was operational from 6-10-2003 to the end of the well (10 November2004).
Standard equipment (depth sensors, pit levels, SPP, MW in/out, pump sensors, torque and RPM sensors…) and
extra equipment were installed: Real time data transmission link to the base, and, from 20-12-2003, high quality gas
detector system type Reserval with GZG constant volume gas trap. This Reserval was in use all along the drilling of
the side-track, with OBM mud.
The gas trap was located on shaker box where the mud enters directly, without “waterfall” inside the flow line to
avoid light gases losses. Two gas sample lines in PVC run between trap and detector, without buckle to avoid water
condensation and deposit; The total transit time was 55 to 65 seconds.

3.4. Hydrocarbon Shows
Comments
The observations were difficult due to Oil Based Mud.
In Los Monos Formation, from 4604 to 4607m, only a few patchy, light yellow direct fluorescence was observed on
Sandstone.
In the Huamampampa reservoir, from 4914 to 4955m, the direct fluorescence was uniform, fair yellow, with a whitish
blue, fast cloudy cut. Down from 4955m to 5009m the direct fluorescence decrease in intensity, and its color trends
to brown. Cut fluo decrease also in intensity, down to 4989m.
Note, between 5019 and 5022m the presence of very few small plaques of brown bitumen, with light yellow direct
fluo and cut.
After 5022m to TD (5600mMD), no shows were observed.

3.5. Gas Shows
The Gas log, and the GWD log (Gas while drilling) are shown in Annex 3&4.
3.5.1. Quality Control
• As in the first ICS-X1 member, line and panel were tested regularly for Quality control .
o The line was controlled twice a day, injecting 20cc methane with syringe in simple aspiration
above the gas trap. Transit time was between 55 to 65 seconds, and value from 4 to 6% of CH4
during the whole well.
o The panels Main and back-up) were checked every 5 days with 1% and 10% gas mixture. The
% errors were 0.5 to 1% for C1-C2-C3, and 2 to 4% for C4 –C5, far away from tolerance limit.
o During the casing set, a long time line – panel (close circuit) output check was systematically
made.
o C1-C5 curves permanent comparison between Main FID and back up (on Winlog file)
As in ICS-X1, the main problem of the quality control stays in the difference between the Total Gas reading (TG) and
the corrected sum SumCor=(C1+2C2+3C3+4C4+5C5).
Theoretically, the ratio TG/SumCor should be equal to 1 +/- 0.2, i.e. between 0.8 and 1.2, and, But in this well,
values around 2 to 4 and locally up to 8 have been observed.
This phenomenon seems to be independent of the types of gas-trap and chromatograph.
It was observed, in first member, with classic FID+ old GZ11 degaser, with Geo-Fast FID + constant
volume GZG gas trap, and with the Reserval + GZG gas trap; the gap still persisted with all
combinations(but less important with classic FID), included the reserval from sidetrack member.
No obvious explanation could be found:
CO2 hypothesis is not possible, because the FID detector does not read CO2.
Heavier gas as C5 could explain this gap; but if they exist, they do not come from organic matter, because bitumen
and asphalt were not seen in the cuttings.
It could be a pollution made by the Oil Base Mud; Some similar events were reported in Algeria and Syria, with the
same mud and weak values of gas done by low porosity (like here).
But in ICS-X1, the gap existed, in water base mud and aerated mud.
Note that Geoservices already encountered this phenomena in several similar wells in Bolivia.
Meanwhile, the data are good, and usable for a GWD interpretation
• Drilling bits effects on the Total gas value and composition (Fig 3.1 and 3.2)
The two figures illustrate the influence of the drilling bits on the gas composition observed in surface. Three
impregnated bits were used, after coring, to the bottom (from 5015.5 to 5150m, for the first one, and from 5172 to
5600m for the two other), with a conventional bit between 5150 and 5172m. From 5172 to 5526m, the Geofast FID
was used, due to a Reserval failure, but it seems that this change did not affect the results. The drilled lithologies
varied between Siltstone, Sandstone and Shale.
It can be seen that the “blue” points, representative of the intermediate conventional bit, follow the “green” and
“yellow” trend, meaning that the cloud “red”, “magenta” and “ochre”, is representative of the influence of the
impregnated bits with turbodrilling.
The “Rock-Eval” effect observed in the first well is still present here. The figures below show an increase of the
Normalized Total Gas, and a diminution of %C1 versus Total Gas, meaning that a greater amount of heavier gases
are extracted.

3.5.3. Gas while drilling (GWD) preliminary analysis
The GWD composite log (Annexe 4) has 6 gas analysis column:
o Column 1: TG and NTG (normalised total gas)
o Column2: C1/C2 and TG/Sum Cor (Corrected Sum of C1-C5 read on the chromatograph) for
theoretic quality control. On ICS-X1-ST1 well, this quality check is not available (see chapter 3.4.1)
o Column 3:’’ Wetness’’(C2+C3+C4+C5)/Sum C) versus ‘’Balance’’ (C1+C2)/C3 curves in opposite
drawing disposition.
o Column 4: C1 and C3; C1 decrease and C3 increase when entering in oil window.
o Column 5: C45 vs C12 to see the heavy gas components evolution with the depth.
o Column 6: C45 and iC5/nC5; same objective as column 5.
See Annex 4.
This chapter synthesizes the “rush” analyses separately done on 8”1/2 and 6” phases of the ICS-X1-ST1 Well, down
to 5150m. On both phases, the mud logging data depths have been shifted approximately 3m downward in order
than the Total Gas variations fit with GR and resistivity. This offset corresponds also with the observed shift between
geological descriptions, in driller depths, and wireline loggings.
8”1/2 Phase
QC:
Meanwhile, the data are good, and usable for a GWD interpretation (Fig 3.3 & 3.4). In details, the possible effects of
the short trip at 4900mMD, and mainly the bit change at 4818mMD might have an influence on this interpretation.
The HC bearing levels obtained with the cut-off agree, more or less, with the Petrolan interpretation
Results:
Gas events seem to be enough significant (Fig 3.5 & 3.6) to indicate the presence of HC bearing levels (see table
below).
Composition analyze leads to identify a single gas signature in both formations (Los Monos and Huamampampa).
The Huamampampa reservoir N1 shows a single fluid behavior, therefore, no contact.
It is not possible to precise the bottom fluid nature.
