Stated investment criteria
What Post Oak Energy Capital says it buys
Read from Post Oak Energy Capital’s own website in August 2026. This is what the firm says it buys, not what anyone has recorded it buying, and figures are shown in the currency the firm itself used - nothing here is converted. Every line links to the page it was read from.
A stated mandate is a firm’s description of itself and was true of the page on the day it was read; firms widen and narrow what they will look at without updating the site. Nothing here is a commitment by Post Oak Energy Capital to consider any particular business, and nothing on this page is represented as being for sale.
Regulatory record
How Post Oak Energy Capital is registered
From this firm's Form ADV, the annual filing every registered and exempt investment adviser makes to the SEC.
| Adviser status | Exempt reporting adviser |
| Regulatory assets under management | Not reported by an ERA |
| Private funds advised | 12 · $1.8bn gross |
| SEC adviser number | CRD 162765 |
An exempt reporting adviser is not required to report regulatory assets under management, so the blank above means the question was not asked rather than that the answer is unknown. Where a figure exists it is the gross asset value of the private funds the firm advises, which is a different and usually larger measure.
