July 2002
Over the summer two major additions to the PDS will become
available to Tigress users. Both these products are already in use
commercially and this is an opportunity for Tigress users to
introduce GIS and engineering aspects to their existing Tigress
workflow.
GeoBrowse
GeoBrowse is a map-based data management and query tool
developed by ISA Ltd in Australia.
GeoBrowse connects to industry databases and standard data
formats creating a single, virtual database environment. It enables
the browsing and display of geographic data from disparate,
non-connected databases via a map display. GeoBrowse also enables
referencing of non-spatial data to any geographical element. In
other words, from the map view queries can be made to obtain
information that is not co-ordinate based. This information can be
linked to a well name, a permit, a basin or seismic survey - any
object on the map - letting the user query directly from the map.
The results can be displayed in tabular form, or sent to
application windows.
The map views can combine data elements from different
databases, and GeoBrowse already has active links to several of the
common industry databases. It is these aspects of map-based data
selection (cross-database), combined with automatic transfer to
editing and viewing applications that Tigress is developing in
conjunction with ISA. Look out for demonstrations of the new
interface later this summer: the new ARC info GIS browser will be
available as an additional Tigress module.
Drilling Optimisation Simulator
DROPS is a Drilling Optimisation Simulator, developed by the
Norwegian company, Drops Technology AS.
The idea behind the product is to simulate the drilling
operation prior to the actual event, to determine the optimum
drilling approach, and thus reduce operation costs. Drops uses
existing drilling data (ROP, lithology type, bits’ hydraulics and
so on) to generate an apparent rock strength log (ARSL). This log
is then used in the drilling simulations to provide a guide to
optimising the drilling strategy for the well, in terms of drill
bit type, hydraulics, and general drilling parameters. Using such
an approach it is possible to optimise the drilling program and
forecast bit wear, and expected ROPs and thus effectively plan the
bit trips to keep rig down-time to a minimum.
Tigress will be adding a data transfer link for DROPS data, as
an extension of the existing import/export system (TIES). In
addition to the obvious advantage this gives DROPS users in terms
of secure and accessible storage of valuable data, all users will
now be able to use the existing Tigress applications to view, edit
and combine more engineering and geological data in the same
applications. Work on this is already underway, and will be made
available to the user base in the autumn.
