...ANALYTICAL PLOTS FOR ANALYSING CONING & CHANNELING IN DIFFERENT RESERVOIRS OF UPPER INDUS BASIN OF PAKISTAN Muhammad Osama Jafri (NED University), Hafiz Haleem ud Din Farooqi (NED University), Waleed Anwar Saleem (NED University) Abstract Water and gas drive mechanisms pose different problems for a petroleum engineer. The most common tribulations encountered are water and gas coning, high permeability layer breakthrough and near wellbore water channeling. In order to identify and differentiate between these tribulations different techniques can be applied. In this extended abstract, the characteristic trends of log-log plots of WOR (Water Oil Ratio) vs. Time will be analyzed for different mechanisms on the basis of proposed techniques by K.S. Chan (SPE Paper No. 30775). The derivatives of the plots show different trends for coning and channeling which makes it easier to interpret the situation. The identification of the problems will contribute to optimize water/gas coning treatments and other encountered problems. This technique has been applied on the wells of Upper Indus Basin (Potwar region) of Pakistan for the identification of coning or channeling in the wells. Introduction In a hydrocarbon reservoir, water is the most abundant fluid existing in the pores with the oil and as a separate phase in an aquifer. Broadly, the produced water can be classified as good water and bad water. Good water is the water which sweeps or displaces the oil and is produced within the economic...

...size of 365 logs being processed. However, actual data provided proved that it was a true sample size of only 362 logs, as data for logs # 30, 123, and 127 are missing from his report. He videotaped 3 operators, April, Sid, and Jim, marking the logs, how each log was broken down and the degree to which the cants were properly centered. Gene then did a comparison of what the cost was of the log in its current condition (actual value), to what would have been the correct value of the log if the cut had been accurate (potential value). This allowed him to see the potential revenue that Welco Lumber Company is losing out on their business (profit gain). Question 1: How much profit is lost on imperfect board cuts? During the processing of 362 logs, it was found that exactly half (181) or fifty percent were processed without error. The remaining 181 logs were found to have undergone some type of error in the breakdown process—excessive log breakdown, off center cant, reduced value cut. As a result, the Welco Lumber Company missed out on $735.14 in potential profit. Taking these results one step further, the potential amount of money lost on each of the 181 logs with errors was broken down into ranges of value lost as shown below. From the graph we can see the nominal value that was lost the most fell between the $1.51 to $4.50 ranges. Question 2: How does performance vary among operators? Below is a table that shows the analysis of each operator by log size, log volume, and...

...M1: Discuss the importance of keeping fault logs Fault logs are used to record the occurrence of danger and faults on a computer, these faults can then be used in the future if the problem happens again so the technician can decide the problem quickly without having to troubleshoot it again. These faults can be problems such as hardware or software errors that require a certain technique to fix this can be listed in the notes in the fault log for the technician to quickly fix the problem. Due to a number of faults that will be recorded a day it is a good idea to keep records on servers so they can be accessed from different locations such as mobile devices and desktop computer with multiple users connected at one time which means that multiple technicians can fix multiple problems simultaneously....

...accesses the relevant sources to answer the user’s query efficiently. Most organizations are familiar with Penetration Testing (often abbreviated to, “pen testing”) and other ethical hacking techniques as a means to understanding the current security status of their information system assets. Consequently, much of the focus of research, discussion, and practice, has traditionally been placed upon active probing and exploitation of security vulnerabilities. Since this type of active probing involves interacting with the target, it is often easily identifiable with the analysis of firewall and intrusion detection/prevention device (IDS or IPS) log files. However, too many organizations fail to identify the potential threats from information unintentionally leaked, freely available over the Internet, and not normally identifiable from standard log file analysis. Most critically, an attacker can passively gather this information without ever coming into direct contact with the organizations servers – thus being essentially undetectable. Very little information has been publicly discussed about arguably one of the least understood, and most significant stages of penetration testing – the...

...Introducing Transaction Log Files Each SQL Server 2000 database has at least one transaction log file and can have multiple transaction log files spread across a number of disks. Each transaction log file is a separate operating system file and is used by only one database. Each transaction log file generally has the .ldf filename extension (this extension is not required). Each transaction log has a logical filename that is used in Transact-SQL statements and a physical filename that is used by the Windows operating system. Additional file properties include the file ID number, initial file size, file growth increment (if any), and maximum file size. Unlike data files that contain pages, transaction log files contain a series of transaction log records. A sequential log sequence number (LSN) identifies each transaction log record. Regardless of the number of physical log files, SQL Server 2000 treats the transaction log as one continuous log. SQL Server 2000 logically divides each physical transaction log file into a number of virtual log files (VLFs). The number and size of virtual log files are determined dynamically based on the size of each transaction log file. Each transaction log file has at least two VLFs. Each growth increment (if any) is treated as a separate physical file with its own VLFs. The number or size of VLFs cannot be configured or set directly by the database administrator. SQL Server 2000 tries to maintain a small number of virtual file logs because it operates...

...Tasks improve the quality of datasets According to (Shankaranarayan & Even, 2009) specific tasks that could be performed to improve the quality of datasets using SDLC are: Auditing. Quality defects occur during data processing (e.g., due to miscalculation, or mismatches during integration across multiple sources), or after data is stored (e.g., due to changes in the real-world entity that the data describes). Addressing these defects requires auditing records, monitoring processes, and detecting the existence of defects. Correction. It is often questionable whether the detected defects are worth correcting. Correction might be time consuming and costly (e.g., when a customer has to be contacted, or when missing content has to be purchased). One might hence choose to avoid correction if the added value cannot justify the cost. Prevention. Certain methods can prevent data defects or reduce their occurrences during data acquisition, for example, improving data acquisition user interfaces, disallowing missing values, validating values against a value domain, enforcing integrity constraints, or choosing a different (possibly, more expensive) data source with inherently cleaner data Data Refinement: Datasets are refined at regular intervals and database is checked for the orphan accounts if any in the system. Orphan accounts may result into dangerous issues so it should be handled carefully. Data Governance implementation: Data Governance Maturity model can be implemented....

Security, Privacy, and User Accounts Question Secure_Leonilo asked on August 22, 2010 How to detect if a Keylogger is installed? Hi, I would like to get some help... I suspect that the computer I use at work probably has a keylogger installed. Could you recommend an online, free, and reliable tool to detect keylogger? Please recommend a couple of tools, so I can try them in case one doesn't detect anything. On the other hand... is it possible to know where the log files generated by the keylogger are sent to? As far as I know, they are sent to an email address that belongs to the person who has installed the keylogger on someone else's computer, so that he can see all the victim types. I suspect that I got keylogger installed from a work partner. thanks a lot in advance! Reply Reply with quote Report abuse Email updates Answer A.

...Presented Problem After examining the incident, there are some key things that stick out as major risks, these include: • Accounts existed before EHR system was deployed. • Accounts were undocumented. • Non Authorized remote users had access to the EHR application. • Undocumented account was created/added to a new system. • Method or Vulnerability to gain privilege escalation outside of change control policy. This led me to propose three policies, each address some of these key issues from separate fronts. The three policies include a Remote Access Policy, Application Deployment, and a Routine Maintenance policy. The Remote Access policy aims to correct the issue that non-authorized users were able to access the EHR system. HIPAA has included provision in the Security Rule that allows for remote access, but with certain limitations. I have included provision that restricts remote access based on Job Role and Job Necessity(ISO 27002:2005, 7.1.1), and restricted to assets that are owned by the hospital which have enhanced security (ISO 27002:2005, 7.1.1) (NIST, 164.312(a)(1))(ISO 27002:2005, 11.4.2). The Application Deployment policy aims to close security loop holes that appear to have been open for months before the EHR system was even deployed. There were no check on accounts when importing, and no alerts when permissions were escalated. Some of the key standards that I see as aiding in creating this policy is better change management (ISO 27002:2005, 10...

...Automated Discovery of Patient-Specific Clinician Information Needs Using Clinical Information System Log Files Elizabeth S. Chen, MPhil and James J. Cimino, MD Author information ► Copyright and License information ► This article has been cited by other articles in PMC. Go to: Abstract Knowledge about users and their information needs can contribute to better user interface design and organization of information in clinical information systems. This can lead to quicker access to desired information, which may facilitate the decision-making process. Qualitative methods such as interviews, observations and surveys have been commonly used to gain an understanding of clinician information needs. We introduce clinical information system (CIS) log analysis as a method for identifying patient-specific information needs and CIS log mining as an automated technique for discovering such needs in CIS log files. We have applied this method to WebCIS (Web-based Clinical Information System) log files to discover patterns of usage. The results can be used to guide design and development of relevant clinical information systems. This paper discusses the motivation behind the development of this method, describes CIS log analysis and mining, presents preliminary results and summarizes how the results can be applied. Go to: INTRODUCTION The availability of clinical information to the clinician at the point of care is essential to the health care process. Inability to locate needed information...

...Chapter 1 A Brief History of Risk and Return Concept Questions 1. For both risk and return, increasing order is b, c, a, d. On average, the higher the risk of an investment, the higher is its expected return. 2. Since the price didn’t change, the capital gains yield was zero. If the total return was four percent, then the dividend yield must be four percent. 3. It is impossible to lose more than –100 percent of your investment. Therefore, return distributions are cut off on the lower tail at –100 percent; if returns were truly normally distributed, you could lose much more. 4. To calculate an arithmetic return, you simply sum the returns and divide by the number of returns. As such, arithmetic returns do not account for the effects of compounding. Geometric returns do account for the effects of compounding and for changes in the base used for each year’s calculation of returns. As an investor, the more important return of an asset is the geometric return. 5. Blume’s formula uses the arithmetic and geometric returns along with the number of observations to approximate a holding period return. When predicting a holding period return, the arithmetic return will tend to be too high and the geometric return will tend to be too low. Blume’s formula adjusts these returns for different holding period expected returns. 6. T-bill rates were highest in the early eighties since inflation at the time was relatively high. As we discuss in our chapter on interest...
