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 economics of the...

Case Study: Integration Drives Performance and Accelerates Learning Curve in an Ultra-Deepwater Pre-Salt Exploration Drilling Project in Brazil

Halliburton integrated services achieves new benchmarks in post-salt and salt sections Challenge – The operator faced many challenges to build exploratory wells in this ultra-deepwater environment, with the main objectives to minimize the significant drilling risks and costs and reduce the total cost of well construction and evaluation. Other challenges included the long 28-inch riserless section in the post-salt formations facing hole instability issues and high...

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 the weather to...

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 installed 11 times...

Case Study: In 1924, Myron Kinley Kick-Starts the Well Control Industry with a Bang

Most well control methods and technologies used today trace their roots back to one man: Myron Kinley Challenges – In the early days of the oil field, blowouts were common, but there were no well control companies around to handle them. Thousands of lives were lost as oil companies struggled to handle dangerous blowouts without the benefits of modern-day well control practices. Then Myron Kinley arrived...

Tech Paper: An Integrated Formation Evaluation Approach to Characterize a Turbidite Fan Complex

Advanced integrated analysis helps reduce overall formation evaluation costs and saves rig-time The oil and gas potential of the basins surrounding the Falkland Islands has attracted exploration drilling that resulted in discovering the Sea Lion Field in the North Falkland Basin in May 2010. Recent exploration drilling has resulted in new oil discoveries to the south of the Sea Lion Complex that has not only confirmed...

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 ranges from 8,500...

Case Study: RapidStart® Initiator CT Sleeve Helps Seneca Resources Pump an Extra Frac Stage

Single toe sleeve increases return on investment Challenge – In horizontal wells, a toe sleeve is used to provide the necessary access from the wellbore to the formation at the toe of the well. Communication between the wellbore and the formation is needed to provide a flow path that will allow displacing either frac plugs and/or frac balls downhole so that multistage fracturing operations can commence....

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, conventional logging-while-drilling (LWD)...

Tech Paper: Saturated Salt and Diesel Emulsion Fluid Reduces Drilling Costs in New Mexico

Direct emulsion water-based drilling mud system helps operator overcome challenges In the Delaware Basin of New Mexico, shallower formations, such as the Salado, include halite and anhydrite layers followed by weaker formations in the Delaware Sands- (e.g., the Brushy Canyon). The fracture gradient difference between these two zones has typically required an intermediate casing string to seal off salt formations before reducing fluid density to drill...
