Hercules 265 jackup drill rig caught fire after a gas blowout and partially collapsed in GoM - Around midday on July 23 2013, a natural gas blowout occurred at the Hercules 265 jackup drilling rig, operating in shallow water in the Gulf of Mexico by Hercules Offshore at a well owned by Walter Oil and Gas corporation off the coast of Louisiana (South Timbalier Block 220). All of the 40+ workers were safely evacuated. The rig was subsequently covered in a cloud of natural gas and caught on fire around 11 pm at night the same day. The fire partially collapsed the platform and the fire was confirmed to be out on July 25th possibly due to the well caved in and sealed itself downhole. (more...)

Featured Article of the Month

Subsea manifold is a flow-routing subsea hardware (subsea flow router) that connects between subsea trees and flowlines. It is used to optimize the subsea layout arrangement and reduce the quantity of risers connected to the platform. If connected to dual flowlines, the manifold can typically accommodate pigging and have the capability of routing production from a particular tree to a particular flowline.. (more...)

Featured Company of the Month

Halliburton is an oilfield services corporation with operations in more than 70 countries. It has hundreds of subsidiaries, affiliates, branches, brands and divisions worldwide and employs over 50,000 people.

The company has headquarters in the North Belt office in Houston, Texas, and in offices in Dubai, United Arab Emirates (opened March 2007), where Chairman and CEO David J. Lesar works and resides, "to focus [the] company’s Eastern Hemisphere Growth." The company will remain incorporated in the United States.

Halliburton has been involved in numerous controversies, including the Deepwater Horizon explosion. The company has agreed to plead guilty to destroying critical evidence related to the 2010 Gulf of Mexico oil spill, the U.S. Department of Justice said on July 25th. It would pay the maximum allowable fine of $200,000 and will be subject to three years of probation.

In the not-to-distant past, Halliburton found itself under scrutiny over accusations that it performed shoddy, overpriced work for the United States military in Iraq, bribed Nigerian officials to win energy contracts and did business with Iran at time when it faced sanctions.(more...)

Assumptions from reservoir simulation have big impact on hydrofrac results (October 2013

Hydraulic fractures can enhance well productivity, ultimate recovery and economics. Although reservoir simulation can quantify hydrofrac performance, simulation outcomes vary. A case study in Oman shows that considerable uncertainty can be removed by understanding the impact of flow dynamics, reservoir architecture, and gridding assumptions, thereby saving time and facilitating planning.

Intelligent tracers quantify in-flow characteristics in multi-zone horizontal wells (October 2013)

Crude oil producers are responding to the reservoir management challenges of multi-zone horizontal wells with intelligent tracers that quantify inflow distribution on a zone-by-zone basis. The inflow distribution analysis from a recent well, equipped with RESMAN RES-OIL intelligent tracers, shows that about half of the total inflow came from only two segments (7 and 8) of a 9-zone well, Fig. 1. RESMAN data also identified two low-producing zones (4 and 5), accounting for only 3% of total inflow. The operator was expecting a more even inflow distribution, and used this knowledge to reassess the reservoir drainage properties and adjust drilling and completion strategy for future wells in the field.

Harsh, complex formations, longer laterals drive innovation (October 2013)

Deepreach.png
Halliburton's DeepReach™ Coiled Tubing Servic uses multiple outer diameter coiled tubing sections in a single string with larger OD sections near the top of the string and smaller OD sections near the bottom.With this arrangement, the tension along the string length is reduced while sufficient flow capacity is retained for performing well intervention operations.

Tapered OD Makes the Difference

The vertical depth capability of conventional coiled tubing is limited because as the length of the tubing string increases in the well, the string’s total weight also increases; therefore, the capability of a conventional CT string to perform ultra-deep work depends primarily on the string’s total hanging weight and the yield strength of the parent metal. If the hanging weight exceeds the pipe’s yield strength, a string separation can occur. Since a tapered coiled tubing string is lighter in weight (compared to a single string of the largest diameter) and its design provides greater strength at the upper end of string, operators can realize up to a 30 percent increase in depth capability over conventional CT strings.

Key Enabling Technologies

Multiple technologies were developed to enable DeepReach coiled tubing to be used in deep well operations. These technologies

include 1) the CT transition joints, 2) Boots & Coots V-Block® gripper design, (more...)
