ABSTRAKSebagian wilayah Kabupaten Cilacap dan Banyumas memiliki tipologi akuifer sedimen terlipat yang tersusun atasbatuan berumur Tersier Formasi Halang, Kumbang, dan Tapak. Penelitian ini dilakukan untuk mengetahui karakteristikhidrolika dan potensi air tanah batuan tersebut berdasarkan analisis uji pemompaan sumur bor air tanah. Hasil analisismenunjukkan batuan tersebut memiliki karakter akuifer semitertekan hingga tertekan. Nilai konduktivitas hidrolikadan permebilitas intrinsik menunjukkan batuan tersebut relatif bersifat sebagai akuifer dengan karakter hidrolika samadengan lanau, lanau pasiran, dan pasir lempungan. Kuantitas air tanah berdasarkan transmisivitas akuifer menunjukkanpotensi jelek hingga sedang untuk kebutuhan domestik, dan potensi sangat jelek untuk kebutuhan irigasi. Nilaikapasitas jenis sumur bor menunjukkan pemompaan dengan debit 1 hingga 2 l/det. masih bisa diharapkan.Kata kunci: karakteristik hidrolika, air tanah, sedimen tersier, uji pemompaanABSTRACTParts of the Cilacap and Banyumas Regencies have folded sedimentary aquifer typology that consist of TertiarySediment of Halang, Kumbang, and Tapak Formations. This study was conducted to determine the hydrauliccharacteristics and groundwater potential of these rocks based on a pumping test analysis. The analysis shows therocks have confined and semiconfined aquifer characters. Based on rock hydraulic conductivity and permeabilityvalues, the aquifer has similar character to silt, sandy silt, and silty sand. Groundwater quantity, based on aquifertransmissivity, indicates poor to moderate for domestic need and insufficient for irrigation purpose. The specificcapacity value shows that pumping rate of 1 to 2 l/sec. can be expected.Keywords: hydraulic characteristics, groundwater, tertiary sediment, pumping test

A simple, approximate but practical graphical method is proposed for estimating the storage coefficient independently from the transmissivity value, provided that quasi-steady state flow data are available from a pumping test. In the past, quasi-steady state flow distance-drawdown data have been used for the determination of transmissivity only. The method is applicable to confined and leaky aquifers. The application of the method has been performed for various aquifer test data available in the groundwater literature. The results are within the practical limits of approximation compared with the unsteady state flow solutions.

Practical value of this work consists in increasing the efficiency of exploration for oil and gas fields in Eastern Baghdad by optimizing and reducing the complex of well logging, coring, sampling and well testing of the formation beds and computerizing the data of interpretation to ensure the required accuracy and reliability of the determination of petrophysical parameters that will clarify and increase proven reserves of hydrocarbon fields in Eastern Baghdad. In order to calculate the most accurate water saturation values for each interval of Zubair formation, a specific modified form of Archie equation corresponding to this formation was developed.
