DrillPro
Overview
DrillPro
is an a full-featured add-on package to
ScadaPro
for the purposes of rig-site surface data
acquisition and processing for both Mud Logging and drilling rig
monitoring in general.
Drilling depth for oil
or gas on land or sea cannot be monitored directly using sensors as it
is expensive and hazardous to put sensors on the drill string. The
current depth of the drill string and the on/off bottom status can be
determined using the length of the drill string passed through a crane,
the weight of the hook used to feed the string, the dimensions of the
drill pipes, the well geometry and the amount of fluid pumped. A complex
algorithm uses these different parameters to calculate the depth in
real-time.
The
DrillPro
monitoring system will allow the operator to display drilling depth and
status without the need for expensive down-hole instrumentation and
using only vendor independent surface instrumentation.
The
associated logging and display system will allow the drilling process to
be analysed
from
a drilling engineering perspective.
DrillPro Features Include:
-
Configurable Depth
Measurement Logic to handle encoders mounted on the draw-works or
crown and geolograph style hookups using switched or level pulse
signals
-
Heave compensation
monitoring is available with encoder input being received from the
riser and compensator.
-
Well Geometry displays
used to drive hydraulic calculations.
-
Facilitates entry of
mud rheology values as required to calculate system pressure drops.
-
Allows up to three
totalisers in any combination each with its own pit volume change
set-point control. Up to 32 tanks are currently catered for and any
pit sensor can be applied to any totaliser.
-
Allows selection of
Bingham Plastic or Power Law models.
-
Facility to define
pump characteristics and to calculate the total output.
-
Lag
Depth Calculations supported.
-
Sets up the off bottom
depth where the system will automatically switch to trip mode.
-
Lag
system can be initialized at any time when the operator wishes to
update the percentage washout factor. Lagged differential values can
also be selected here. The "bottoms-up" time is continuously updated
in terms of time, volume and total pump strokes.
