The number of MLPs will increase, according to 88.5% of respondents informally polled at Ernst & Young's Energy Executive Insight session in Houston recently. The findings are based on responses from senior financial executives from various Houston-based energy companies, the majority of which are in E&P. In other findings, half the group believes private-equity investment would result in more development of unconventional reserves and 46% expect it to result in increased competition for a limited amount of traditional reserves. Meanwhile, 34% expect private equity to drive up finding and development costs, due to increased competition for equipment and personnel. Some 15% believe private investment could lead to higher oil prices.
