Lateral

Texas Eastern said it had finished valve repairs on its Venice Lateral in the East Louisiana Zone (see Daily GPI, July 26) and brought the line back into service Thursday morning, allowing affected production to resume at scheduled volumes. Shipper imbalances incurred during the brief outage may be made up through the end of the month, Texas Eastern said.

On Tuesday, the day that Transwestern was scheduled to end maintenance on the dehydration unit at Ivanhoe Station on the Lipcomb/Mocane Lateral (see Daily GPI, July 10), the pipeline announced that the work has been extended through July 18 due to unavailability of parts. The project is impacting 80,000 MMBtu/d.

Sea Robin reported completing an investigation of a leak in its “J” leg segment (see Daily GPI, May 16). The “J” leg is being returned to service after the leak was isolated on the lateral serving Eugene Island Block 305 (receipt location 94027), Sea Robin said. It resumed taking nominations for Thursday’s gas day at all affected points except for location 94027.

CIG plans smart pigging of the Uinta Basin Lateral in late May. On May 23 and again on May 27, flow from Natural Buttes Compressor Station must be cut to about 100 MMcf/d for about 10 hours each day. For 27 hours beginning on May 25 and again on May 29 for about 27 hours, flow from Greasewood Station to Wamsutter Station must be reduced to about 100 MMcf/d. Construction work related to the Pipeline Integrity Program (PIP) will require the shut-in of Table Rock Residue volumes for 16 hours on May 17. PIP construction will require sections of the Wyoming mainline between the Laramie and Cheyenne Compressor Stations to be removed from service for short periods (less than 24 hours) May 1 and 2 and again May 10-12. Impact to service is expected to be minimal. No service intereruption is anticipated during May 7-8 PIP construction between Cheyenne Compressor Station and the Cheyenne meter station.

Citing “lack of supply from CMS Energy” (Panhandle Eastern) at the Gas City (IN) Compressor Station interconnect on the Lebanon Lateral, Texas Eastern said it restricted scheduled volumes there for Wednesday’s gas day. Should conditions at the meter remain unchanged, the restrictions will remain in place today, Texas Eastern said. However, a Panhandle Eastern spokesman said the shortfall resulted from customers in the frigid Upper Midwest taking extra supplies from the pipeline and causing a pressure drop at Gas City. The pressure was back to normal by Wednesday afternoon and the shortfall resolved, he said.

The various owners of the Black Marlin Pipeline System, a75-mile long natural gas and condensate gathering system in theGulf of Mexico, have sold the line to Williams Field Services for$9.25 million. The line was purchased from Blue Dolphin Energy, a50% owner, MCNIC Pipeline & Processing Co., a 33.33% owner, andWBI Holdings, Inc., a 16.67% owner. The sale includes related shorefacilities servicing the High Island area. Ivar Siem, chairman ofprimary owner Blue Dolphin, said the company had purchased BlackMarlin in early 1999 “during a period when the system hadexperienced lower throughput volumes due to limited drillingactivity in the High Island area. Since then the activity level hasbeen very high and significant additional reserves have beendiscovered,” Siem added. “This is an opportunity for us to realizegood value for the asset. We can re-deploy a portion of the saleproceeds to other niche pipeline opportunities in the Gulf.”

Citing unanticipated delays, Tennessee said Tuesday thatrehabilitation work on its Donna Lateral in South Texas, scheduledfor Oct. 23-24, must be extended at least into today. Until furthernotice, nominations will continue to be refused at 18 meters.

Williams has been selected in a “landmark transaction” toinstall the infrastructure, including gathering lines and onshoreprocessing, to service new deep water development in the Nansen andBoombang Fields in the East Breaks area of the Gulf of Mexico.

NGPL said it is completing all work on the offshore Texas HighIsland Block 71 Lateral and the line will become available for serviceagain today. A leak was discovered Aug. 16 and about 50 MMcf/d ofproduction from three receipt points was scheduled to zero effectiveAug. 18 (see Daily GPI, Aug. 23). NGPLwill begin scheduling gas for the High Island 71 (Torch) and HighIsland 116 (Vasgas) wells today. However, the High Island 139 (Sonat)well has been disconnected and is under evaluation at this time, sountil further notice the pipeline will not schedule gas there.
