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...

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 batch drilling and...

Tech Paper: A New Logging-While-Drilling Azimuthal Density Sensor for Large Borehole – Gulf of Mexico

Unique service helps address formation evaluation challenges encountered in large borehole sizes In the current market, operational geology and geoscience asset teams have clear and aggressive financial reduction target that need to be met without compromising the formation evaluation (FE) requirements of a well construction project. Advances in drilling and completion technologies and practices for deep-water wells commonly require operators to drill larger borehole sizes throughout the...

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 customer set a...

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 by numerical simulation,...
