The GSS Pore Pressure Analyst identifies opportunities to improve service delivery, implements standard work, and manages risk during service delivery. This person monitors the well to provide timely information to our customers; maintain sensors, equipment, and data acquisition equipment; and delivers high quality data to the customer at the wellsite. Come join one of the world's most diverse and inclusive groups of industry experts. Together, we create amazing technology that unlocks access to energy for the benefit of all.
This is a Client facing role, candidate will work in both SLB and the clients office in Houston, Tx.
Roles and Responsibilities
Be familiar with customer drilling plan, pre-drill pore pressure prediction, structural geology
and pressure generation mechanisms which may be present.
Meet appropriate client personnel and attend pre-spud meeting if possible.
Confirm and plan for location at well site, if at wellsite. Preferably close to LWD and Mud
Logging units.
Confirm WITSML server data streaming from LWD tools and any other streaming data source
such as mud logging data (Gas, ROP etc...). Always have backup solution (webserver, USB stick).
Ensure that everyone on the various teams (Operator, Driller, SLB, GSS ML, Others)
understands the role and responsibilities of the PreVue Analyst while both onshore and
offshore.
Calculate vertical stress from Bulk Density (RHOB) and/or velocity data. Check if water depth
is correct and edit RHOB values for salt or carbonates if necessary. Ensure vertical stress profile is supported by all available data.
Calculate shale pore pressures from LWD, Mechanical, and Shale Density data (GR, Res and/or
Sonic, D-exponent, RHOB) using the current model (i.e., calibrated to all available data points),
compare it with the pre-drill predictions and identify deviations.
Calculate fracture gradient from real-time pore pressure and vertical stress using the current
model (i.e., calibrated to all available data points), compare it with the pre-drill predictions and
identify deviations.
Update pressure and fracture models as new information (LOT's, MDTs, RFTs, WL data, etc.)
becomes available. All changes to the models, for calibration purposes, should be reviewed
and approved by the Client Team before publishing a report on pore pressure estimations for
the project.
Consult pre-drill PPFG predictions frequently and insert plots in all reports.
Provide a prognosis as to what magnitudes of pore pressure and fracture gradients are
expected ahead of the bit (if offset wells and seismic data are available).
Identify potential hazards if current drilling practices are continued over the next 24 hours.
Gather and summarize all other relevant pore pressure indicators (back ground vs. connection
gas, ROP, caving, etc.). This data should be used to support the pore pressure models.
Compute gas ratios to identify if related to underbalance environment or wellbore breathing.
In the event of influx or losses, gather and summarize all indicators. Give special attention to possible prior indicators or decisions made that may have caused the event.
Determine from all sources available where the influx or losses are occurring, and the
mechanism of losses.
Use this data and information to calibrate the pore pressure and fracture gradient
models.
Analyze LOT's and summarize interpretation and update Fracture Gradient model along with
Fracture Closure pressures/EMW. Ensure all latest model updates and interpretations are
communicated to the Client Team offshore and in town.
Using ESD and ECD, inform drilling supervisor if wellbore pressure is outside the PP-FG window
in the open hole.
