Drilling dynamics models play an important role in drilling performance optimization. These models can be classified as engineering tools or research tools, depending on functionality. Case studies from disparate drilling applications around the world have demonstrated that performance can be improved by applying lessons learned from advanced dynamics models.

Alternative isolation techniques have been introduced for either complementing or even suppressing the need for well cementing. Tailored cements range from basic to highly technical ones to fit almost any well requirement. The versatility and adaptability of these cement based solutions to fit well “cementing” needs make it a key element in today’s well architecture, as wells can be designed differently taking into consideration the properties of these new cementing materials.

Hydraulic fracturing has been described as one of the three most significant technologies to be developed in the upstream oil and gas industry in the last 50 years. The successful application of hydraulic fracturing to mature oil and gas reservoirs is about recognizing that there is a wide range of appropriate solutions available. A number of case histories are used to illustrate the effectiveness of these techniques, when they are systematically applied.

In Colombia’s Cusiana and Cupiaga fields, initial well rates were disappointing, mostly because of a combination of difficult perforating conditions and significant drilling induced damage. A team was formed to determine if and how BP could fracture stimulate in the most effective manner possible. This team proposed a number of solutions for both the fields that were subsequently implemented. Issues that were addressed included coping with well deviation/azimuth, rigorous prefrac wellbore preparation, novel fracstring deployment, fracturing and an efficient remedial stacking of fracs.

Kutubu is Papua New Guinea’s largest oil field. It came on line in 1992 and
achieved peak rates in 1993 before decline began in 1994. A follow up
development campaign, along with other projects, has for 4 years completely halted the production decline. The field now appears to have a considerable remaining life of up to 2 decades. This lecture’s main conclusion is that we regularly need to go back to basics and establish whether or not our fundamental assumptions are supported by solid evidence.
Neil Williams is currently in charge of the reservoir engineering, geoscience, planning, and development of the Kutubu field for Oil Search. He earned a BS degree from Sydney University in applied mathematics, and a PhD degree in fluid mechanics from the University of New South Wales.
