Gas Storage Design and Evaluation

Platt, Sparks addresses problems specific to the gas storage industry from the initial identification of gas storage reservoir candidates to the verification of gas storage inventory volumes. These services also include the specification of storage facilities (wells, base gas, gathering systems and compression) required to meet the needs of gas distribution and pipeline companies. In addition to facility requirements, Platt, Sparks has the experience and tools necessary to design operational scenarios to meet the challenges of the ever-changing natural gas industry.



Platt, Sparks performs reservoir characterization studies using geostatistical analysis techniques. The results of these studies are used primarily in developing reservoir description data for use in reservoir simulation studies. Reservoir characterization analyses are also useful as stand-alone studies for assessing fluid-in-place distribution and displacement efficiencies.


Litigation - Expert Witness - Court's Expert

Platt, Sparks' professional engineers serve as expert witnesses for presentation of engineering studies and evaluations. Previous litigation experience has included representation before State Courts, Federal Courts, arbitration panels, State regulatory commissions, and Federal agencies. We also have the unique experience of serving as a Court's Expert, advising the court on the significance of technical evidence presented in oil and gas litigation.


Log Analysis

Regulatory Conformance

Platt, Sparks represents clients before oil, gas, and other regulatory agencies. We offer expertise in compiling supporting data and in evaluating and presenting technical studies for applications, filings, and regulation compliance. Our engineers regularly testify at contested hearings on rule exceptions, unitization, secondary recovery projects, pooling, special field rules, and gas production regulation. Other services include personal expediting of time-critical Railroad Commission filings and research of Railroad Commission documents.


Reservoir Simulation Studies

Platt, Sparks conducts reservoir simulation studies to examine primary, secondary and tertiary hydrocarbon recovery. Platt, Sparks' personnel have experience in the application of simulation models to reservoir engineering problems throughout the world. Access to state-of-the-art simulation technology allows Platt, Sparks to select the most appropriate modeling techniques for application to specific reservoir engineering problems.


Secondary and Enhanced Oil Recovery

Activities include the initiation and development of new projects for secondary and tertiary recovery. Platt, Sparks has experience in the "screening" of potential secondary and EOR candidates, feasibility assessment and the optimal design of production strategies using secondary and EOR methods. Existing secondary and tertiary recovery projects are analyzed for possible modification to boost production and ultimate recovery.



Services include representation of individual companies on technical committees or preparation of independent third-party unitization studies on behalf of all operators. These studies include the development of ownership participation formulas acceptable to participants and in compliance with regulatory requirements. Platt, Sparks will monitor and recalculate participation factors subsequent to unitization as interests and conditions change.
