Tank Battery Consolidation

Many oil and gas fields have multiple operators or working interest owners. In addition, most fields consist of a number of separate leases (common royalty ownership, etc.) that require individual oil and gas processing (separation, treating, storage and transfer, etc.) facilities to account for production to each owner. Technical Data used in the field explained in diploma in petroleum technology.

LACT initially was applied to these separate lease operations. The automatic transfer of produced oil and recycling of unacceptable quality oil [high basic sediment and water (BS&W) content] to treating facilities increased the effectiveness of treating and storage equipment.

In addition, tire incremental cost of larger meters, pumps, and related equipment of LACT’s was low compared to the increased oil volume transfer capability. Thus, a technical basis was available to process and transfer much higher produced-oil volumes than present on the average lease. Some more details of diploma in petroleum technology are as under.

Historically, individual lease oil-production volumes had been treated to pipeline quality (2 % BS&W or less) before custody transfer from the lease. In the 1960’s, regulatory agencies began to approve operator requests to commingle wet-oil (not pipeline quality) production from multiple leases into a common or central oil processing and custody transfer facility. Oil production from each lease was determined by measuring the wet-oil volume (separator positive-volume or positive displacement meters, etc.) and correcting for water content with automatic samplers and later with capacitance probes and related net-oil computers. Final sales volume to each separate lease was determined by allocating the custody transferred (sales) volume back to each lease on the basis of its proportion of total wet-oil lease measurements. In other cases, tank battery consolidation was implemented when a field was unitized under a single operator for initiation of secondary recovery activities.

Tank battery consolidation eliminated oil treating and storage facilities on the individual lease. In some fields, the pipeline trunk lines used to gather individual lease oil volumes were converted to wet-oil gathering lines for the consolidated tank battery operation. Tank battery consolidation converts a field’s operation from a number of stand-alone lease functions to a central process with multiple inputs. Oil treating and storage, water treating and disposal, vapor recovery facility, etc., became more efficient and controllable in the consolidated environment.
