This paper reports that the use of multiple horizontal sections from a single vertical well bore has increased well potential and improved the economics of producing the Austin chalk. The vertically fractured Austin chalk formation in central Texas is difficult to drill from both technical and economic perspectives. Torch Energy Advisers Inc. recently completed a unique northwest-southeast dual opposing lateral horizontal well, the Basden No. 1-H, in the Austin chalk in Fayette County, Tex. The Basden No. 1-H well plan had to overcome some of the drilling challenges inherent in the vertically fractured Austin chalk in the Fayette County area of the Giddings field, including the following: High bottom hole pressures; Strong kicks that could deliver large volumes of oil and gas to the surface; Harsh drilling fluids (CaCl{sub 2}); High temperatures (270-280{degrees} bottom hole circulating temperature); Major faults with large geological throws; and Minimal distance between the base of the ash and top of the Eagleford shale.
