The FOCUS ℠ service has been designed as an ongoing temperature monitoring system which is capable of taking measurements along the entire length of the fibre and creating real time temperature profiles with immediate results. It is equipped with a portable system enabling to view the resulting data in your work station through the use of specialized software. Aside from this feature, the service includes reliable interpretation of the data during the service monitoring ant time you may need them together with a quantitative and qualitative analysis of the flow profiles of your well based on the temperature profile created

AIP S.A.S. has formed an strategic alliances aimed at providing data capturing services in production and injection Wells using fiber optics technology.  Asesoría en Ingeniería de Petróleos S.A.S. having  over 20 years experience in the oil and gas industry is pleased to introduce its new services  - FOCUSSM in Colombia using DTS fiber optics technology which provides greater flexibility, efficiency, easy visualization and interpretation of the results by adjusting to its needs and requirements. 

1.TYPICAL INSTALLATIONS

PERMANENT
Cemented capillary in the annular along the well’s full depth

SEMI-PERMANENT
Cappillary anchored to the tubing or injection pipe along the well’s depth

TEMPORARY                                                                                                                                                                                                             A capillary located in the annular, between the tubing/injection and the casing along the entire well

2.DTS SYSTEM

This is a portable system in various shapes that can easily accommodate to the well surface environment. It is equipped with adaptors to different visualization software types rendering it possible to tailor it to your individual needs.  

3.APPLICATIONS

• Creation of real time temperature profiles along the entire length of the well  

• Detection of fluids in isolated zones behind the casing

• Optimization of production throughout the well’s life

• Creation of the Gas Lift valves behaviour profile

• Applications in Heat Recovery Operations (SAGD wells).

• Production/Injection monitoring in each perforated zone

• Stimulation Monitoring

• Monitoring of Artificial Lift & CBM wells, gravel packed wells and intelligent completions

4.Features and advantages

• These data allow users to visualize various zones simultaneously thus permitting the interpretation of multiple temperature profiles, aside   from providing optional 3-D visualization of data through time.  

• The fiber optics coating renders it possible to expose the tool to temperatures of up to 700 ºC during prolonged times.

• Decreased operation costs since there is no need to stop any alternate operations while the monitoring is done

• This system is equipped with a visualization module that acts as a multiple data receiver that can receive data from up to 8 wells located in  the same area

• The spatial resolution of the probe is of up to 1 meter and the simple resolution is of up to 0.5 meters maximum

• Minimizes the need to run any additional jobs or production or injection logs

• Capability to obtain real time accurate and dynamic profiles of up to 40,000 points for a complete monitoring in the flow line

• Intrinsec sensor that can be permanent or temporary and does not produce a spark

• Accuracy of the data along the entire well and during the operation

5.OUTPUT

• Monitoring of production, injection and SAGD (Steam injection)

• Flor input calculations

• Evaluation of Injection profiles

• Effectiveness of fracture jobs  

• Detection of cement plugs behind the casing

• Detection of cross flow between the zones.

• Identify potential problematic intervals when production diminishes

• Tracing of a thermal event in space and time through 3D visualization of the data

• Evaluate the behavior of the well and identify its properties through time production, injection and acid job

• Evaluate the steam chambers in SAGD wells in order to gain improved understanding of the steam injection process

• Improved understanding of the processes that take place inside the well through uniform sampling indicating the time and position of the temperature changes.
