Description

  The Colombian Cusiana and Cupiagua developments, in the Llanos foothills of the Eastern cordillera of the Andes mountains, comprise a giant oilfield (Cusiana) and a giant retrograde gas-condensate field (Cupiaga). Discovered in 1992 & 1993, they were subsequently developed fast-track with over 15 drilling rigs running at the peak of the operations in 1997.

In both fields, initial well rates were disappointing, mostly due to a combination of difficult perforating conditions and significant drilling induced damage. However, more concerning than this was that as well production history was obtained, it became increasingly clear that the relative permeability effects were unusually severe in these quartz-arenite formations and that associated decline rates on the wells (due to GOR and condensate banking) were dramatic and severe. 

Typically wells would have been immediately fracture stimulated to address this. However, early experience had already demonstrated that the regional tectonic effects were quite considerable and as the completions had not been designed for high-pressure fracturing operations and with many wells already drilled, this presented a significant complication.

In response to this, 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, which were subsequently implemented. Issues that were addressed included coping with well deviation/azimuth, rigorous pre-frac well-bore preparation, novel frac-string deployment, fracturing (for condensate-banking) and an efficient remedial stacking of fracs.

Production rates increased dramatically and the decline(s) and condensate-banking issues were reduced, allowing the economic development of the two fields to continue.

BP EXPLORATION CO., LTD

  Martin Rylance is a Senior PE and Engineering Advisor with BP Exploration. He has been with BPX, their partners and JVs (SOHIO, Maxus, TNK-BP) for over 20 years.

 During his time with BP, his positions in the company have included: Head of Fracturing and Stimulation for BP Worldwide, Interventions Team-Leader with BPX in Colombia, Team-Leader with TNK-BP in Moscow and more recently Project Manager with VICO in Jakarta. 


Technically, he has been involved in all aspects of pumping operations, well-control, well interventions and pressure service, hydraulic fracturing, snubbing, stimulation, coiled-tubing, PWRI and cuttings re-injection. In recent years he has specialized in fracturing in tectonic regimes, HPHT environments and also mature field re-development. During his career with BP he has been responsible for the implementation of many campaigns and more than 5,000 frac & stimulation treatments around the world. 


He graduated with a BSc (Hons.) in Pure Mathematics. He has numerous papers and publications to his name with the SPE, AIME and various Numerical and Geological Societies, articles, reports and patents. He is an active Member of the SPE. He is also a Fellow of the Institute of Mathematics in London.
