Mariner I-85 well finds gas
Canadian Superior Energy Inc. of Calgary, Alberta has encountered gas on the Canadian Superior El Paso Mariner I-85 well in multiple zones as targeted. The company found the high bottom hole pressures, experienced in offset discovery wells, at the depths anticipated.

New tool enables cost-effective multilateral re-entry
The decision to prepare multilateral wells for later re-entry traditionally had to be made during initial well design, before confirming that production data warr-anted the investment. The potential necessity for wellbore cleanouts, formation damage removal, acid stimulations, nitrogen lifts, or wellbore logs was just too great to avoid upfront installation of sophisticated completion hardware.

Active heave drilling drawworks system goes to work
Hitec's first Active Heave Drilling (AHD) drawworks is now in use on R&B Falcon's newbuild drillship Deep water Pathfinder. The Stavanger-based company has sold a further four units to the same contractor, two for drillships and two for semisubmersibles. The second unit is now installed on Deep water Frontier and due to come into operation in April. A further three units have been sold to Sedco Forex for installation on its three advanced new semisubmersible, and one to Navis for the

Intensive drilling sustains Lake Erie gas production
Drilling barge Mr. Chris. Relocating pipelines once fields exhaust Gasfield/processing activity in and around the Canadian side of Lake Erie. [128,501 bytes] When Talisman Energy bought Pembina Resources in 1997, it gained over 100 million boe of proven and probable reserves. The package also included some of Canada's most productive offshore acreage - in Lake Erie, Ontario.

Mobil hunting new outposts within and beyond Arthurian kingdom
Mobil North Sea reaps a significant portion of its income from its equity share of gas from 17 Southern Basin producing fields, on six of which it is operator. This year they will account for 44% of all Mobil's production revenue and 72% of after-tax income. On peak days the fields can supply 1 bcf/d of gas to UK customers via the gas terminals at Bacton and Theddlethorpe. The six operated fields can deliver around 300 mcf/d.

DRILLING TECHNOLOGY Reservoir damage problems multiply in horizontal drilling
Leonard LeBlanc Editor More extensive damage can be done to reservoir productivity in the drilling of horizontal wells than in vertical holes because of the greater exposure of the reservoir to borehole fluids. The remedies for that damage, if available, can be costly. Frustrated completion engineers make the point that the additional cost and effort in drilling horizontal sections to enhance productivity come to naught if the reservoir has been damaged by borehole fluids, the formation skin or
