The
aim of DBDP is to be the center of information services for Yemen Oil Industry,
thus, it is very important that the information contained within are managed
properly by the personnel involved, following the guidelines in place. In
addition to that, the technology used in managing those information plays an
important role in assisting the process. DBDP is powered by the latest hardware
and software technology to ensure the performance and reliability of the system.
Hardware Technology
The
data in DBDP repositories are managed and served by two powerful Sun Solaris
servers that is designed to be redundant. The servers provides database services
as well as application services for the data loaders. The end users will not
have direct access to these two servers, instead they will access the data
through two web servers (read only) that is connected to the database. The first
(main) web server is accessed directly by the end users, while the second one is
providing GIS map service to the main web server.
There are two types of backup implemented in the system. The first one is daily
online backup, controlled by Legato backup application using ADIC scalar system.
The snapshot of the system is automatically stored daily on the backup system,
ready to be used for recovery purpose. The second type is the offline backup,
where a snapshot of the system is copied to the offline storage. This type of
backup provides redundancy to the online backup.
The
network system is powered by Cisco switch capable of delivering 1GB of data per
second, supported by network cards on each machine that also have the same
capability.
Software Technology
DBDP
is today equipped with the essential data management software and the required
operational Policies and Procedures. The data management software provides the
ability to capture a wide range of field data including seismic, geological,
geophysical, production, drilling and interpreted data. DBDP has defined the
quality control processes to agreed standards in order to maintain the quality
of data provided by PEPA and the Production Operators in Yemen. However the
ownership of the data and its correctness will always remain with the owners of
the data. DBDP registered users utilize a friendly web interface to browse, and
order data, access to which can be done either from within DBDP or the company’s
sites, provided communications exist.
The security and
confidentiality of PEPA and the Production Operators’ data assets are the
corner-stone of the DBDP service. DBDP has established data security policies
and will keep track of the accessibility of data. Data security rules will be
applied to all registered users of the DBDP to only allow access to data they
are authorized to see and at the same time, prevent any unauthorized access of
the data by non-authorized users.
The web access provides a
simple and secure way to access the data. This web access is powered by
Schlumberger's DecisionPoint technology, which connects to various data
repositories in DBDP, and present the data in integrated form. The users will be
able to visualize the data and do quick analysis of the data, as well as drill
down to more detail.
The following screenshots
shows how the user view the data stored in DBDP.

Summary of weekly production for each material
(oil, water, gas, water cut, fluid) in a gauge format, measuring the target
production against the actual production. |
The drill down from the production gauges to the
periodic production in an interactive chart format, for an easy analysis of
each production material over time. |

The drill down from the production gauges shown on
the At A Glance Weekly screen. Here it displays the current production
figures for each production element compared to the previous production,
showing whether the difference are within the
threshold
or not. |
Summary of
drilling activities for a specific well. It shows the breakdown of activity
based on a pre-defined categories (drilling, logging, cementing, etc) as
well as time vs. depth chart, actual cost vs. planned cost, mud weight, ROP
and hours on bit chart. |

|
The interactive map that
provides a spatial view of the information resides in the databases, as well
as the capability to drill down to more detail information. |
The availability of
various well information (logs, markers, cores, etc) displayed based on the
depth of existence, which are also have the capability to drill down to
retrieve the actual data stored in the databases. |

|
|
|
 |
|
The interactive log
viewer, enables the users to quickly retrieve the log curves from the
database, and display them on the fly. |
One of the many reports
available. This one shows the monthly production report along with the chart
that shows the information visually. |

The interactive
wellbore
schematic for a specific well, where the users can view the historical
wellbore
schematic since the well was drilled. |
