Question

Q1 While drilling a well offshore, the following leak-off test results were obtained: Leak-off pressure 200 psi; true vertical depth to the casing shoe = 1,000 feet TVD. The test was conducted with 8.60 ppg seawater. Calculate the strength of the formation at the casing shoe to the appropriate two digits past the decimal. a) 12.45 ppge b) 12.44 ppge c) 12.43 ppge d) 12.46 ppge Directional Drilling Well Path Planning Q2 This is normally done where a vertical or close to vertical entry into the reservoir is preferred but the surface limitations require the surface location to be on the side of the reservoir entry point a) Type 1 - Build and Hold b) Type II - Build, Hold, and Drop c) Type III - Deep Kick-off Point d) Horizontal well Q3 In this kind of well profile, continuous build does generally have less horizontal displacement than the other well path profiles. a) Type 1 - Build and Hold b) Type II - Build, Hold, and Drop c) Type III - Deep Kick-off Point d) Horizontal well Q4 There are many drilling problems to be overcome in drilling this wellbore profile, such as hole cleaning, torque & drag, differential sticking, getting enough weight on bit, logging, and getting casing to bottom: a) Type - Build and Hold b) Type II - Build, Hold, and Drop c) Type III - Deep Kick-off Point d) Horizontal well Q5 For the following S-shaped well designed to avoid a salt dome, using the following data: Kick-off depth = 1,200 ft Build-up rate = 2.0 degrees/100 ft Drop-off rate = 3.5 degrees/100 ft TVD at end of drop-off section (V4) = 8157 ft Total horizontal displacement (D3) = 2136 ft Final inclination angle in reservoir = zero degrees
