... Abstract An operator in Mexico was seeking a solution for improving methods for acid stimulation treatment in open-hole wells. Previous bullheading acid treatment in the same field was less efficient compared with selective treatment according to production conditions. In the shallow waters...

... Abstract The execution of Open Hole Horizontal Gravel Packs (OHHGP) in ultra-deep waters (greater than 1500m) demands the use of the best technologies available. For the Atlanta Project, a detailed description of the first two wells successfully completed with OHHGP in the field, was provided...

... rig cost deepwater environments. The only solution to drill an open hole intersecting multiple reservoirs and being able to selectively produce and isolate the required zones in an OHGP with shunt-tube screen was to utilize the OHMP. The OHMP also provides the ability to perform a shutoff of the lower...

Length of the open hole in producers ranged from 150-1,960 ft. 5 ½ inch 12 gauge wire wrap screen with shunt tubes was installed in open hole and gravel packing performed using a water based viscous fluid, with packing through shunt tubes taking place at some stage in most...

... Abstract Open hole gravel packing of reservoir sections drilled with oil based fluid is traditionally performed with an aqueous carrier fluid. This typically involves displacing oil based fluid to aqueous fluid once the gravel pack screen is in place. In reservoirs with swelling or unstable...

... and even the screen size vs. open-hole diameter can also have a significant impact. Productivity impairment issues originally encountered on Rosa producer wells (Deep offshore Angola, Block 17) led to the development and testing of a unique micro-emulsion technology in 2006, for use with coiled tubing...
