Upward revisions were primarily related to a non-operated field covering multiple wells, which experienced difficulties during the remediation process coupled with scope change due to the size of its platform.  In addition, another non-operated field experienced difficulties with a sub-contractor that had gone bankrupt and a replacement sub-contractor is attempting to re-negotiate the contract.  We do not have control over the remediation projects for non-operated properties.  Along with these two non-operated fields, we had upward revisions at two fields that were operated by us which experienced sustained casing pressure issues during the remediation process.
