SPE/ICoTA conference to showcase technologies, real-world applications for well interventions

spe

Knowledge sharing and innovation are the key benefits of attending this year’s SPE/ICoTA Coiled Tubing and Well Intervention Conference and Exhibition, according to Ian Chapman and Matt Billingham, Chair and Vice-Chair for the upcoming event. The conference takes place 27-28 March in The Woodlands, Texas. Mr Chapman and Mr Billingham agree that, after several difficult years for the industry, the acceptance of interventions as a critical maintenance tool, both from a reservoir management and production enhancement perspective throughout the life of a well, has become critically important...

Proppant intensity may increase by 35% in Permian Basin before reaching optimal economics

Figure 3: Wells in the Delaware-Wolfcamp sub-play are expected to reach an NPV maximum at a proppant intensity of 3,000 lb/ft. Proppant intensity as of mid-2017 was reported to be 2,200 lb/ft.

To maximize well productivity in the current low oil-price environment, operators in North America have adjusted their completion designs and substantially increased their proppant use. At $50 oil prices, that trend is expected to continue – particularly in the Permian, where our analysis indicates that proppant intensity will rise by 35% before reaching optimal economics. The resulting increase in North American demand – up from 45 million tons in 2016 to 110 million tons in 2018 – will be a boon for suppliers and a key driver of low-cost sand flooding into the Permian...

Comparison of Haynesville wells shows benefits of tighter cluster spacing, higher proppant loads

optimization

Techniques for optimized completions shown to result in higher EURs, flattened decline curves By Kelli Ainsworth Robinson, Associate Editor Optimized completion techniques – including longer laterals, tighter cluster spacing, and higher proppant loads and stage counts – can significantly increase the number of conductive transverse fractures and the estimated ultimate recovery (EUR) of Haynesville wells. The finding was made by Halliburton and Dallas-based E&P company Covey Park Energy in a study comparing two Haynesville wells – one completed in 2010 and one in 2016. Additionally, the study found that modern completion techniques can flatten the decline curve in Haynesville wells. The evolution of completion designs in the Haynesville have been driven, in large part, by the play’s low reservoir permeability, ...

Expandable liners enhanced for more precise, reliable refracs

screen-shot-2018-01-30-at-10-12-52-pm

Enventure has launched its enhanced versions of its ESeal RF and ESeal RFHT refrac expandable liners at the 2018 SPE Hydraulic Fracturing Technology Conference and Exhibition, held 23-25 January in The Woodlands, Texas. The Enhanced ESeal RF and ESeal RFHT provide 16% and 45% higher strength, respectively, than the original ESeal RF Liner. This has expanded the operating envelope for installations using higher treatment pressures and in higher temperature reservoirs, which could exceed 300°F. The liners now offer more predictable zonal isolation and better ID preservation, said Matt Meiners, Technology and Product Development Manager at Enventure. The enhancements were made in response to recent surges in refracturing programs as operators seek to increase production and estimated ultimate recoveries of shale wells. Watch ...

Coiled-tubing frac sleeve with collet locating system improve BHA placement in extended-reach laterals

screen-shot-2018-01-30-at-10-13-15-pm

Coiled-tubing frac sleeve systems are gaining popularity due to their ability to deliver stimulation treatments to a large number of stages in extended-reach laterals. However, many of these systems rely on depth correlation for bottomhole assembly (BHA) placement, which can be imprecise. As a result, these systems often cannot accurately locate sleeves once they’re installed downhole. In response to this challenge, Baker Hughes, a GE company, developed the Blitz coiled-tubing frac sleeve system, which was launched at the 2018 SPE Hydraulic Fracturing Technology Conference in The Woodlands, Texas. In this video from the conference on 23 January, Scott Sanchez, Product Line Manager-Unconventional Multistage Completion Systems, explains how the Blitz’s collet locating system enables more accurate BHA placement. He also discusses the results BHGE saw when the system was deployed for an operator in Alberta, Canada...

Inspection tool uses high-definition frequency to identify corrosion in up to five tubular strings

screen-shot-2017-10-16-at-10-31-43-am

Metal corrosion can cause serious well integrity issues and nonproductive time. Halliburton launched the Electromagnetic Xaminer V (EPX V), which can identify corrosion and casing defects in up to five strings, at the 2017 SPE Annual Technical Conference and Exhibition in San Antonio, Texas. In this video from the conference on 10 October, Freeman Hill, Product Manager – Well and Reservoir Surveillance, describes how the EPX V uses high-definition frequency technology to provide a through understanding of pipe defects and metal loss throughout the well. He also discusses the various deployment methods, including slick line, for the system...

Acoustic telemetry network provides real-time data during deepwater frac pack completions

screen-shot-2017-10-16-at-10-35-10-am

Most of the telemetry platforms in existence today don’t provide real-time data during completions. XACT Downhole Telemetry developed its acoustic telemetry network to provide pressure, temperature, tension, torque and bending data during completion operations. At the 2017 SPE Annual Technical Conference and Exhibition in San Antonio, Texas....
