“…The serial communication could be local, through a cable, or could be obtained remotely through another real-time-operations data acquisition and management system that uses advances in software operating systems, networking, telecommunications and Internet/Intranet access to allow users to have access to the data regardless of their locations. 10 Another option to collect slickline data is through a memory card installed in the AMS panel where the operator can save the information and retrieve it later.…”

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractThe technological enhancements, new tools, versatility, and cost efficiency of slickline services have increased its usage considerably in the last decade. However, an efficient method to capture the integrity of slickline wire prior to its use has not been available until recently. This paper will discuss a new Real-Time Wire-Management System that has been developed to predict the used life of the wire in slickline operations. The system uses a general wire model to detect fatigue failure in the wire. The model results are accumulated for the whole life of each drum of wire, and then, when the use life exceeds predetermined levels, the operator can remove the slickline tool and can make appropriate changes to the wire. A specified amount of line can be cut off to move the bending point to a new location, or the line can be reversed, extending the life of the whole unit by moving the operation to wire that was located previously at the core of the drum. Finally, the system can help the operator determine when a drum of wire should be discarded completely. Field applications have shown that this system can result in enhanced reliability in slickline operations and that cost savings from reductions in catastrophic operational events can be significant.

“…DST data obtained through the acoustic telemetry system can be linked real-time to a drilling system database platform [4][5] . This database platform then allows operators to monitor and query data from a variety of DST sources (e.g., separator instrumentation, surface pressure/ temperature, bottomhole pressure/temperature, etc.).…”

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractIn the past, in order to acquire real time, bottomhole SRO (surface read-out) data, either a downhole latching system or a download probe in close proximity to the transmitting device had to be used. An innovative SRO system that takes advantage of state-of-the-art developments in acoustic technologies, wireline, and wireless transmission, and yet, is compatible with tools conventionally used during drill stem test operations has now been introduced to the industry. This acoustic data-acquisition system provides access to real-time bottomhole data using either a wireline-deployed probe or via wireless acoustic signals sent through the production tubing. If the probe is used, this does not have to be close to the transmitting device in order to transfer the data to surface. Since the system offers the option of transmitting via wireline or via the wall of the testing pipe, the need for a probe or latching device along with the inherent problems that sometimes occur because the probe becomes stuck in the latch or mechanically fails can be eliminated. Finally, the additional rig time required for preparation and running of the probe to move the Acoustic Telemetry System (ATS) transmitter up to proper depth is saved, reducing operational costs. BackgroundEarly SRO systems required a mechanical downhole latch mechanism that required wireline in the hole for communication of the information from the downhole probe to the surface. For low-rate, low-pressure wells without any H2S or CO2, use of this type of system posed few potential problems. However, as the industry pursued testing of deeper, higher-capacity wells with greater concentrations of impurities in the well effluent, several safety issues were experienced with the use of wireline in the hole. In the late 1980's and early 1990's, various intermediate SRO systems used electromagnetic proximity probes to alleviate some of the safety issues and to improve the operational reliability of the SRO systems. However, these systems did not address the fundamental problem of using wireline-deployed signal pick-up probes. The realization of the advantages that a reliable wireless method of communicating downhole data to surface could provide is not new, and the oil industry began searching for a wireless method of communicating downhole data to the surface over 50 years ago. One of the first documented field tests was performed in 1948 to study the response at the surface of a downhole hammer. The results were not encouraging, and the project was dropped. As technology evolved, interest in wireless telemetry rekindled. Several companies revisited acoustic telemetry and developed research projects to address transmission of acoustic signals through tubing. Significant work by Barnes and Kirkwood in 1972 1 and, by Douglas Drumheller in 1988 2,3 helped the industry to understand how the acoustic waves responded to the tubing at various frequencies. Based on the principles laid by the earlier work, several companies now offe...

Testing to evaluate the potential of a new well or field is a common practice in the oil and gas industry. When performing this task in a deep-water environment, however, there are significantly more challenges for the operator and service company to address, and when testing a heavy oil reservoir, the challenges are even further exacerbated. Special consideration must be given to the following issues: 1. High rig rates associated with deep-water operations will make job problems more costly. 2. Producing heavy crude oil to surface, moving it through the surface production train, and finally, disposing of it in an environmentally acceptable manner. 3. Deep-water environment exposes the crude to an extended period of heat loss and low temperatures while it is in the landing string.In order for the well test to be effective, all the above conditions must be fully understood and methodology employed that will reduce the chance that operational risks will occur. This paper will discuss the successful testing of a heavy oil reservoir in deep water. A number of different ways to assist the production of heavy crude in the deep-water environment will be presented, and the relative merits and limitations of each will be considered. The discussion will provide an outline of the necessary additions to the surface production train and the use of chemicals and heat to ensure flow. Finally, it will consider what equipment is necessary to properly dispose of the produced fluid.The testing methods discussed in this paper can be applied to heavy-and low-pour-point crudes in deep water. The equipment and methods can also be used in shallow water applications or on land. The case history data will illustrate: 1. Why particular methods and equipment were used and why others were rejected.
