Integrating Fractional Flow Into Reservoir Surveillance Improves GOM Production
A case study in the deepwater Gulf of Mexico in which pressure transient analysis, fractional flow, and production logging tools were integrated to identify correctly the cause of, and execute an effective remedy for, a well’s productivity deterioration.
Evaluation of a Riser After 10 Years of GOM Service Life
As part of an effort to evaluate existing riser systems, an operator launched an inspection and testing program to investigate risers retrieved following well abandonment after a service life of nearly 10 years in the Gulf of Mexico.
Latest Gulf of Mexico Lease Sale Generates Moderate Bidding Interest
The largest lease sale in the history of the area attracts $139 million in total bids, a $2 million increase over the previous lease sale held last August.
Advances in 4D Seismic and Geophysical Monitoring of Deepwater Fields
Integrated surveillance is critical for understanding reservoir dynamics and improving field management. A key component of the surveillance is areal monitoring of subsurface changes by use of time-lapse geophysical surveys such as 4D seismic.
Field Trials Help Boost Processing Capacity of Offshore Facility Above Nameplate Limit
The Constitution spar in the Gulf of Mexico has an original nameplate separation capacity of 70,000 BOPD and 200 MMscf/D of gas. Production potential from future developments is expected to exceed this limit.
Systematic Coiled-Tubing-Efficiency Improvement Reduces Operational Time
Deepwater coiled-tubing (CT) well interventions can benefit from significant rig-time reduction and cost savings associated with improved efficiencies of surface processes.
New Deepwater, High-Pressure GOM Tubular Maximizes Capability, Reduces Cost
A 2-year comprehensive effort to design, test, manufacture, and deploy a new high-pressure completion tubular for Chevron’s deepwater Gulf of Mexico (GOM) operations is presented.
New Improvements to Deepwater Subsea Measurement
A RPSEA project identified the gaps in technology that are the most pressing for multiphase-flow measurement.
Implementation of an Acoustic Automatic Leak-Detection Sonar in the Gulf of Mexico
The authors have developed an active acoustic automatic leak-detection sonar designed to detect hydrocarbon leaks (mono- and multiphase oil and gas) at significant ranges, allowing coverage of wide areas from a single sensor.
Process Support and Marine Systems in a Spar Hull: Innovation Meets Regulation
Historically, the marine systems on a spar are relatively simple.
Single-Gradient Subsea-Mud-Lift-Drilling Technology in Deepwater Gulf of Mexico
As with other MPD systems, SMD technology offers early detection of influxes (kicks) and minimizes downhole losses to weak subsurface formations.
Waterflooding Proves Useful in Deepwater Gulf of Mexico Overpressured Turbidites
This paper is a detailed examination of Pleistocene-to-Upper-Miocene turbidite reservoirs in the deepwater Gulf of Mexico under water injection.
Liner-Drilling Technology Mitigates Lost Circulation Offshore Mexico
This paper will demonstrate the benefit of liner-drilling technology used to drill and cement an operator’s 9⅝- and 7-in. liners in place.
Dual-Gradient Drilling in Ultradeepwater Gulf of Mexico
A previous attempt to drill an exploration well in ultradeep water in the Gulf of Mexico (GOM) did not reach its objective.
Comparing North Sea and Deepwater Gulf of Mexico Produced-Water-Treating Systems
In terms of platform technologies and extraction strategies, there are fundamental differences between the North Sea and the deepwater Gulf of Mexico (GOM).
