1. If a well initially at a pressure of 3000 psi is shut in, and after 1 hour the pressure increases to 3200 psi, calculate the pressure buildup rate. 2. During a drawdown test, a well with an initial reservoir pressure of 4000 psi drops to 3800 psi over 2 hours. Calculate the pressure drop rate. 3. Calculate the average flow rate if a well produces 500 barrels of oil over 10 hours. 4. If the absolute open flow (AOF) potential of a well is 8000 Mcf/day, calculate its daily production rate in cubic feet. 5. Given a reservoir with a porosity of 20% and a total compressibility of 0.00011/psi, calculate the compressibility factor. Formula Equations 1. Pressure Buildup Rate: Pressure Increase/Time 2. Pressure Drop Rate: Initial Pressure - Final Pressure/Time 3. Average Flow Rate: Total Production/Production Time 4. Daily Production Rate: AOF Potential 5. Compressibility Factor: Porosity \times Total Compressibility

Let $A = \begin{bmatrix} 1 & -3 & 0 \ -4 & 0 & 2 \ 2 & -2 & 2 \end{bmatrix}$ and $b = \begin{bmatrix} 7 \ 16 \ -6 \end{bmatrix}$. Define a transformation $T: \mathbb{R}^3 \rightarrow \mathbb{R}^3$ by $T(x) = Ax$. If possible, find a vector $x$ whose image under T is $b$. Otherwise, state that $b$ is not in the range of the transformation $T$. A.) $\begin{bmatrix} -5 \ -2 \ -4 \end{bmatrix}$ B.) $\begin{bmatrix} -5 \ -4 \ -2 \end{bmatrix}$ C.) $\begin{bmatrix} -5 \ -4 \ 0 \end{bmatrix}$ D) b is not in the range of the transformation T.
