Case Study: Single-Trip Multizone Cased-hole Frac Packs and Intelligent Completions Improve Recovery in Subsea Gas Field

Advanced completion solution enables wells to remain fully functional after five years of production Challenge – The operator needed to improve operational efficiencies for this complex subsea field of shallow, low pressure, and weakly consolidated gas reservoirs. The field required a method of dealing with unconsolidated sands, along with the ability to monitor and control each of the six potential layers as the...

Case Study: eRED® Valve Provides Efficiencies and Time Savings in Downhole Operations

Valve operates remotely after 23 months down hole Challenge – The operator’s previous method for hanger installation and completion testing involved the deployment of a dual-bore riser and multiple intervention runs to allow for plug installation on the annulus bore. This can be a time-consuming operation, especially as the North Sea is subject to adverse weather conditions that can result in waiting on...

Case Study: eRED® Valves Save 88 Hours of Rig Time for Upper Completion Project

Remotely operated valves eliminate requirement of costly interventions To achieve its goals, Shell elected to pre-install the remotely operated Halliburton eRED® valve as a shallow barrier in the tubing hanger. This allowed Shell to have a secondary barrier in place without the requirement of an intervention before removing the blowout preventer (BOP) and installing the Christmas tree. In total, the eRED valves were...

Case Study: Summit ESP® Successfully Replaces Rod Lift System

Multi-technology solution generates USD 1.4 Million in revenue for operator in just six months Challenge – Rod lift systems have their own challenges, especially in extreme conditions with excessive gas and high depths. Gas is compressed within the pump itself before actually producing liquid. Solids fallback is also an issue, particularly in the Bakken formation. The client had wells with pump set depth...

Tech Paper: A New Ultra-deep Azimuthal Electromagnetic LWD Sensor for Reservoir Insight

New tool helps optimize well placement during the development of a reservoir In the development of a reservoir, optimizing the well placement in the desired formations from pre-well modeling techniques is a challenging task. Existing well-planning techniques, such as offset well logs or surface seismic data, do not provide the required level of accuracy and can result in high uncertainty in geosteering decisions. Conversely,...

Intercept® Retrievable Bridge Plug Provides V0 Barrier on Two Batch Wells with Zero NPT

Halliburton retrievable bridge plug helps ensure stability and safety Challenge – This operator needed to rent barrier plugs in order to temporarily abandon its wells to drill and run batch completions. Normally, the operator rented bridge plugs from another service company. Halliburton discussed the well challenges with the operator and recommended the Intercept® retrievable bridge plug because of its gas-tight V0 barrier during...

Case Study: Integrated Well Intervention Solution Reduces Offshore P&A Costs By Over 50 Percent

Solution becomes new P&A benchmark in offshore field Challenge – In the field, the platform had been unmanned and the drilling facility idle for 10 years, requiring costly upgrades to be prepared for the plug and abandonment (P&A) campaign. The P&A solution had to comply with strict environmental and internal company technical requirements, and also reduce overall decommissioning time for the platform. The...

Tech Paper: Redevelopment of an Unconventional Oil Reservoir: Finding Unstimulated and Bypassed Reservoir Volume

Increasing oil production in a tight carbonate formation through re-stimulation opportunities This paper identifies re-stimulation opportunities in existing horizontal wells with existing multistage hydraulic fracturing to increase oil production in a tight carbonate formation, offshore Black Sea. Pilot candidates were screened and ranked through the following decision criteria described in this paper, coupling reservoir, production and completion parameters. Favorable pilot candidates were verified...

Tech Paper: Optimization of Recovery Using Intelligent Completions in Intelligent Fields

Completing smart wells with remotely controlled inflow control valves Throughout the previous few years, substantial attention has been paid to the usage of smart well technologies to help improve recovery, particularly with technological improvements and an increasing expanse of opportunities in more challenging and rewarding assets. The fundamental focus has been to propose and develop workflows that integrate several surface/subsurface sub processes and...

Case Study: BaraShale™ Lite Fluid Enables Sustained Success of Unconventionals in Low-Cost Oil Environment

New water-based fluid system helps operators save time and reduce costs Challenge – With its unconventional field developments, the outstanding success of the Permian Basin as a global oil and gas swing producer has been sustained by operators and service companies using innovative technologies and cost-efficient operational practices. Overlying much of the hydrocarbon-rich Delaware Basin – the western province of the Permian Basin...
