Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the ordinary course of conducting our business, we become involved in litigation and other claims from private party actions, as well as judicial and administrative proceedings involving governmental authorities at the federal, state and local levels. While the outcome of litigation or other proceedings against us cannot be predicted with certainty, management does not consider it reasonably possible that a loss resulting from such litigation or other proceedings, in excess of any amounts accrued or covered by insurance, has been incurred that is expected to have a material adverse impact on our consolidated financial statements. Escrow Claims Related to the Sale of the Environmental Services Business Under the terms of the March 2014 sale of our previous Environmental Services business to Ecoserv, LLC (“Ecoserv”), $8.0 million of the sales price was withheld and placed in an escrow account to satisfy claims for possible breaches of representations and warranties contained in the purchase/sale agreement. In December 2014, we received a letter from Ecoserv asserting that we had breached certain representations and warranties contained in the purchase/sale agreement, including failing to disclose operational problems and service work performed on injection/disposal wells and increased barge rental costs. The letter indicated that Ecoserv expected the damages associated with these claims to exceed the escrow amount. In July 2015 we filed an action against Ecoserv in state district court in Harris County, Texas, seeking release of the escrow funds. Thereafter, Ecoserv filed a counterclaim seeking recovery in excess of the escrow funds based on the alleged breach of representations and covenants in the purchase/sale agreement. Ecoserv also alleged that we committed fraud in connection with the March 2014 transaction. Following commencement of the trial in December 2017, we reached a settlement agreement with Ecoserv in the first quarter of 2018, under which Ecoserv received $22.0 million in cash, effectively reducing the net sales price of the Environmental Services business by such amount in exchange for dismissal of the pending claims in the lawsuit, and release of any future claims related to the March 2014 transaction. As a result of the settlement, we recognized a charge to discontinued operations in the fourth quarter of 2017 for $22.0 million ($17.4 million net of tax) to reduce the previously recognized gain from the sale of the Environmental Services business. The reduction in sales price was funded in the first quarter of 2018 with a cash payment of $14.0 million and release of the $8.0 million that had been held in escrow since the March 2014 transaction. In March 2018, the lawsuit was dismissed with prejudice. Litigation expenses related to this matter are included in corporate office expenses in operating income. Kenedy, Texas Drilling Fluids Facility Fire – Subsequent Event In July 2018, a fire occurred at our Kenedy, Texas drilling fluids facility, destroying the distribution warehouse, including inventory and surrounding equipment. In addition, nearby residences and businesses were evacuated as part of the response to the fire. In order to avoid any customer service disruptions, we implemented contingency plans to supply products from alternate facilities in the area and region. While this event is covered by our property, business interruption, and general liability insurance programs, these programs contain self-insured retentions, which remain our financial obligations. Although the total costs associated with the event are not currently estimable, we expect to record approximately $1 million to $2 million of charges in the third quarter of 2018 related to this incident, primarily reflecting our self-insured retention obligations under the insurance programs.
